Hello, Sandbox VPN gateway will not reply to ICMP/ping by design. Check to see if the ports are blocked from your SRC. The port range will be anywhere from TCP 20100 through TCP 20354. Give that a try and you should be good to go. If that's not working, keep in mind VPNs also use TLS (TCP 443) and DTLS (UDP 443). Though typically these are open in most organizations.

Hope this helps.

Hi,

 

I have confirmed that outbound traffic is allowed, but still can't connect to devnetsandbox-emea-gwy.cisco.com using anyconnect, I think the issue is with VPN termination point

 

 

% telnet devnetsandbox-emea-gwy.cisco.com 20209
Trying 173.38.221.89...
Connected to devnetsandbox-emea-gwy.cisco.com.

Thank you,

Try tethering of your cell or via another provider

 

(venv) $ telnet devnetsandbox-emea-gwy.cisco.com 20209
Trying 173.38.221.89...
