can't resolve hostname when on VPN; what's up with the DNS?

I've got VPN service running on Tiger Server. When I'm logged into the machine directly (terminal), I can ping my other machines by name (it resolves the IP addresses fine). However, when I'm logged in through the VPN from home, these same machines cannot be reached by name. What DNS settings am I missing? Clearly the server knows how to resolve these. Why isn't it letting the VPN do it? I'm using DigiTunnel as my client. Thanks,

I don't know specifically about DigiTunnel... but with my VPN I have to use the internal IP's to connect to everything, in other words, if I had server.company.com setup as a public IP I couldn't go to server.company.com in file sharing since it can't resolve the public IP over the VPN.

I think that's the problem I'm having also - I need to use the internal IPs. But isn't that a bug that can be overcome? We have internal DNS servers that know my machines by name; why can't the VPN use that info to resolve the name?

are you having the VPN hand out your local DNS servers IP address to put in for your computer? Or are you manually putting in your local DNS server IP? If not... you need to make sure to put that in somewhere so it knows to use it. I'm attempting to set this up myself actually, running into a bit of an issue since I'm hosting both my internal and external DNS on the same machine. But I'm learning alot about views 🙂

Have you told it to?

Normally, opening the VPN tunnel would override the client's DNS server settings so that you can resolve internal hostnames, but it has to be setup in the VPN server in order to do that.
