VPN Client problems after accessing the Lab.

Hi,

I have problems with connectivity after the VPN client connected to lab:

C:\Users\user>ping 192.168.254.11

Pinging 192.168.254.11 with 32 bytes of data:
General failure.
General failure.

Ping statistics for 192.168.254.11:

C:\Users\user>ping 192.168.254.1

C:\Users\user>

(I cant ping .1 address witch is next hop-hop to access devices in my lab. Also, I cannot ping my own address)

Client version 4.7.04056

Tested on Windows 7 and Windows 10.

I haven't had any problems in the past with accessing different labs.

Thanks,

Which sandbox are you seeing this issue?

Thanks!

As i see the sandbox, once you are connected on the VPN you connect to the Ubuntu host running on the C480ML on IP address: 10.10.20.40. You can follow this learning lab for more of a guide HERE - hope this helps!

Hi,

That is not the case. I cannot access any of the networks via VPN.

As you can see (attachment), I've received and installed the networks that are accessible via 192.168.254.1.

I'm happy to provide the logs/debugs from VPN client.

Failure to ping the next hop (192.168.254.1) or even my own address means something is wrong with the VPN or configuration.

I tried to use different machine with different operating system - same problems.

Thanks,

Antek

When your VPN is connect you can ping or access the devbox?

Host: 10.10.20.40
Username: developer
Password: nvidia1234

From the command line this can be entered as:

ssh developer@10.10.20.40

Thanks!

Hi,

The 10.10.20.0/24 network is behind 192.168.254.1.

I cannot ping or access (ssh) anything related to this lab/sandbox.

As I stated before - I cant ping 192.168.254.1 nor 192.168.254.11 (my IP address assigned by VPN client).

Thanks,

Antek

I test this sandbox just now and it set up with no error, sorry this has happened. Please reserve another instance and give that a go, if the issues persist I will ask ENG to look at this. If you have an error please provide your lab id.

Thanks!

Hi @bigevilbeard

I tried to reinstall the VPN client - no luck.

I have the same problems - cannot ping or access anything in the Lab.

I have also deployed the latest Debian (10) and installed Anyconnect on it - same story: unable to ping or connect to any device in Lab.

Are you able to check this with engineer?

Sandbox ID:
b4e4adbc-461c-4f40-94f0-8402f35c0f48

If you check the logs on the VPN termination device (either ASA or something else) you should see couple of my attempts.
However, no luck with routing/accessing the Lab devices.

Thanks,

Antek

I provided you ID to ENG and ask for this to be checked.

Thanks!
