I have set up my router on my local network to use dynamic dns (no-ip) to get a "static" hostname. I have forwarded port 22 to my local pc and I can remotely log into it using ssh. I also need the machine to connect to a vpn network to reach servers that I have to work with. Unfortunately, as soon as I start vpn, I get disconnected and can no longer re-connect using the static hostname. I can still ping the hostname, since the router will answer, but I can not ssh to the machine I need to reach anymore.
ssh: connect to host myhostname.no-ip.biz port 22: Connection timed out
I am using vpnc to connect to the vpn, however, it is a custom build provided by my university. They state that the usual vpnc client is not compatible. They also provide a configuration file which looks like this
IPSec gateway vpn.uni-mannheim.de IPSec ID doniluma IPSec secret wlan IKE Authmode hybrid CA-File uni-ma.pem Xauth username myusername
And a certificate file. Is there a possibility to adjust routing or similar, so I can (re)connect after initialising the vpn with vpnc-connect ?
