Exclamation VPN frustrations... connection not working

I'm trying to establish a VPN connection for the first time, to the server at work. I have all the details for Windows users and I've been trying to make them work with pptpconfig and KVpnc but to no avail. Background info - I've opened a hole through my firewall for all ports, just to eliminate that potential issue.

KVpnc seems to get nowhere. Aside from the UI being completely confusing, I just get these messages:

Quote:

pptpconfig seems to get a little further, but it never completes the connection. It gets this far but then no further, so I'm unable to use the ping button:

local IP address 192.168.0.31
That's with the routing set to "all to tunnel". If I set it to "client to LAN" then it doesn't reach the final line (quoting a local IP address).

I'm stuck and frustrated. Can anyone explain to me what I'm doing wrong?

Re: VPN frustrations... connection not working

Part of the problem is that I can't see any useful feedback from the programs. Does anyone know of a trick to get more debugging back to help trace the problem?
