Tom Roche a écrit : > > SUMMARY: I seek to tunnel an F5 SSL VPN (hard requirement) through an OpenVPN server (apparently required) in order to shell into a compute cluster behind a firewall. I can access the required F5 remote-access website (RAW) through the OpenVPN tunnel, but lose DNS once I activate the F5VPN using the RAW's web GUI. I suspect this is due to a problem with my OpenVPN configuration, since direct access using the F5VPN (unfortunately now disallowed) worked for me in the past; specifically I suspect my OpenVPN server is not enabling my F5VPN client to see/use the DNS server(s) inside the firewall. One thing I don't understand. In you web page, you wrote : > good news: I can still ping IP#s, e.g., > > $ ping -c 4 www.whatismyip.com > PING www.whatismyip.com (141.101.120.15) 56(84) bytes of data. > 64 bytes from 141.101.120.15: icmp_seq=1 ttl=56 time=95.1 ms (...) > bad news: DNS fails, e.g., > > $ nslookup www.whatismyip.com > ;; connection timed out; no servers could be reached But your ping command requires name resolution to retrieve the IP address to send the packets to. Does it send a DNS request or did you add www.whatismyip.com to your /etc/hosts file ? If the former, can you capture and compare the DNS traffic of the two commands ?
