Cisco vpn connected but cannot ping

The Cisco VPN client would connect successfully. However, I could not access any resources on the LAN behind the firewall. This line was singlehandedly preventing me from accessing internal LAN resources. To fix this, I entered the following commands:. What this line does is allow VPN users, who are connecting from behind their own firewall, to traverse multiple levels of NAT and reach the remote inside subnet. The numeral of 30 is the keep-alive value and is specified in seconds. So, I thought I would list some other common causes for this problem.

If not check the attributes on your remote-access tunnel-group. You should see a line that says something like this.

Cisco VPN connects but cannot access inside resources

Your configuration should have a line that reads something like this:. These are networks that will receive network address translation. From here, check the access-list that the NAT statement referenced. You should have one that reads something similar to this:. As long as you have an access-list, are applying that with a NAT statement, NAT traversal is turned on, and you are receiving an IP address, you should be able to browse resources behind the inside interfaces.

As always, would love to hear from you. So, if there is anything else that could be a common cause for Client VPN traffic not flowing be sure to leave a comment! Thanks heaps and keep up the good work. Could you take a look a it? Hey i have the exact same issue where i cannot ping the inside interface from the VPN pool Ip…i tried the above but didnt work.

Can you please assist. I can foward the configs for you to have a look. I can take a quick look.Hello everyone - I have inherited a SonicWALL firewall that was installed at a client's site by a previous service provider. I typically use Cisco hardware, but so far no complaints with the Dell hardware. There is a VPN configured in the firewall, and everything looks pretty standard as far as Phase 1 and Phase 2 settings go. Like I mentioned, connection is easy, and I can ping the gateway So, with sonicwalls I've only done client vpn using sonicwall netextender, their client vpn app.

It's possible that when you have the client connection initiated, you don't have a route to the network your servers are on. You could try adding a route manually in windows to test this, just point the route to lan as your dgw when connected to vpn. Or, what I recommend if this is not in production - remove the old vpn config and start from scratch using the official documentation.

You'll see how it's setup start to finish, and probably have a better grasp. Try setting up a new client vpn and use netextender assuming you're licensed for it.

How To Fix VPN \

Not sure if you already saw my post and skipped over it, but I had originally posted the wrong article. I would check the new link and make sure you've followed the steps. I think 'Allow connections to' needs to be changed from 'split tunnels' to 'this gateway only' and then you will need a NAT policy for returning traffic I believe. So if this is L2TP, you need to define the destination network s for clients to access. Mike - it isn't connecting over L2TP. I can confirm this by looking at the L2TP Server tab and verifying that there are no active L2TP sessions while I am connected even refreshed a couple of times for good measure.

The problem is getting to any network resource on the LAN. You will please forgive me because I am new to SonicWall. I prioritized this rule to the top of the list. I then disconnected my VPN connection, and then reconnected.

Behavior is the same LAN, X0 subnets, etc Then when you are configuring the connection you can select the SonicWall network adapter.

B4dyce75 - the user has been given access to "LAN Subnets". Groups is set to "Everyone" and "Trusted Users". Everyone, thanks for your patience. I feel I am really close. When I click to save the rule, I get the following message:. I'm a little fuzzy on this particular message - I haven't encountered it before.

Netextender is actually really good. Both of you were really helpful, and I'm sorry for any frustration that my newness to SonicWall hardware may have caused. To continue this discussion, please ask a new question.

You should also check these settings on your local site's Dashboard network to ensure that the subnet you're connecting from is also advertised. For example, if Are any firewalls blocking this traffic on the network?

Are there any problems reaching out to non-VPN peers? Try sending pings or traceroutes to public IPs such as 8. Try pinging the public IP of the other MX from your local network.

Are there routes configured on both sides that point to the remote subnets? If the MX is not the only gateway in the network e. Make sure any other routing devices on the network have a route that allows them to access the remote VPN subnets via the MX's local IP address. Are these devices on non-overlapping subnets? If the device on each end is on a subnet that overlaps with the other side, the MX will be unable to route traffic to the other side as it will believe the traffic is destined for the local network.

It is recommended to have unique subnets with no overlap on each network connected to the VPN. If identical networks are required on each side of a tunnel, you may need to enable VPN Subnet Translation. Please note that this feature does not allow for partial overlap between subnets, and is not supported with non-Meraki VPN peers.

I've been down the nat road, double checked ACLs but I'm not seeing the issue. ASA Version 8. Is this the actual address that you get? Make sure you are getting a valid IP because that does not seem right.

Other than that, I'm not seeing anything out of place. Yes that is what is showing up when I do ipconfig on the client machine. I tried multi pools and they all give the same subnet and gtw.?? I will recreate the pool and see what happens. I do not have access to a updated Anyconnect client, I inherited this network last year and they didn't want to pay for the Cisco smartnet contract.

Under the Cisco virtual adapter, what does it show for your gateway? I believe the problem may be with your inside route statements on the ASA. Traffic can make a one way trip, but not a return trip if it's beyond that first hop. Your nat statements look backwards according to every configuration I have saved.

From my home computer physical line directly connected to the modemI can connect to the company Cisco router successfully and gets assigned the IP I can ping the Cisco router and the network printer without any problem. However, I cannot ping the two access points and cannot access their web admin interface. I try to ping them from the Cisco router and find that they can respond the ping request. So I can confirm that the Cisco router can actually reach them.

Also, other computer hosts in the company can access the internet through these two access points without any problem. And they can ping and access the web admin interface of these two access points. I also tried to turn off the firewall in the Cisco router to make sure it's not the cause but it still does not solve the problem. So why can't my home computer ping and access the web admin interface of the access points when it's connected by VPN? To circumvent this you should:. Also, the question is, are you going to access those APs on regular basis, or is it just a once-in-a-while configuration?

What you mean is, when my home computer accesses the APs, they see the source IP as my home computer public IP rather than the I access these APs on regular basis.

No, they see it as So the APs should not know these packets in fact do not originate from the local network.Having a bit of an issue with Windows 10 and VPN connections at multiple locations we look after.

Problem started after the creators update, users couldn't access their mapped drives once connected to the VPN - we shortly found that the client device could nslookup the location fine, but couldn't ping or access it without a host entry pointing it in the right direction. I've tried various things, including turning on split tunnelling but yet the issue still occurs. The real weird bit is some people are affected and not others, and then say a week or two later, it will then be other people that are having the issues.

Very hit and miss. The value is 1 to disable, 0 to enable smart resolution. Maybe there's something in my settings wrong and just creating a whole new setup might straighten it out. I actually solved it by taking the client's network to a different IP range because both server and client were It's now working flawlessly.

Are the networks they are connected to the same as the office network IP? If so, that will be the problem. Are you querying an internal server by name or ip address with nslookup? Have you configured the local client Nic to append a DNS suffix?

If you are using the windows VPN client then what you are reporting sounds a little like an issue with windows updates. Yep, If the network they are connecting from is say They're different subnets.

I was querying the netbios name, domain name, and server FQDN via nslookup and all gave successful addresses. When using ping, it doesn't even resolve the address as it "cannot be found". When you say "host entry pointing it in the right direction" I assume that means you are adding local entries to their HOSTS table in windows to resolve the IP of the servers they need to reach? Seems to me regardless of how they resolve the IP Via DNS or a local hosts file the capability to ping should not change as long as both methods get the same IP.

I would not try to disable IPv6 yet, that should not be necessary and disabling it may come back to haunt you later. LOCAL Think I'm confusing things, nslookup returns the correct information. Understood, maybe a clean install of the creators update workstation can be used to test.

Does that work? I would change your metric on either the local connection or your vpn. The default is setting for the local adapter will force it to use its dns first, not the dns server assigned by the vpn. It happens at multiple businesses we look after so figure it's either a configuration issue or a general W10CU issue. Is there any way I can deploy that?

If setting the metric works for you then you can also set it via the command line. I dont believe you can set metric via GPO but a logon script may work. Often, after Windows 10 updates itself, it will shut off network discovery. Essentially, this changes the device's default network from Private where we like our systems to dwell and we leave our permissions open to Public wherein usually permissions are closed off.

I've had this happen on a few PCs in our company; it disrupts things like scan-to-folder capabilities with our copier, Ping, and simple identification from other network nodes.

I didn't see this mentioned above--sorry if I overlooked it--but perhaps take a look? To adjust the metric value on an interface, do something like:.He is unable to ping any device on our network by IP or name.

No other users are having any issues with the VPN, only this one. Does it have something to do with his home ISP? He is getting a public IP address and it doesn't appear to have any network overlap with our internal subnet except subnet mask. I'm hoping someone will see something I am missing. ASA config and User Route print attached. Thank you in advance for any suggestions!

I've had the issue you describe where everything is working for other users, but it randomly doesn't work for someone The problem can be confirmed by connecting to the VPN then right-click on the gold lock and choose "Statistics The problem can be fixed simply be re-installing the Cisco VPN client on their machine thereby recreating the virtual network adapter which is somehow related to this issue, but I haven't been able to figure out another solution.

Also, if they open the VPN client, they should see a list of your internal networks and it should list it as allowing access.

They connect to your Firewall by IP. I did try flushing DNS, but no change while connected from his home network. Is the network he is having issues from have the same addressing as the network he is connecting to? I have found that some end users set their home routers up to pass the same addresses as work. They have just enough network savvy to cause issues.

Not sure if this could be the issue or not but I had a similar issue before due to double Natting by the ISP. I had the end user explain this to their ISP and it resolved the problem. Another potential reason for the problem could be just plain routing.

This may give you a least a clue as to what's up. You may even discover that you have overlapping private address space with their home network. There is no router in the mix, the user connects directly to a cable modem. I did verify that there is no network overlap.
