VPN

Hello,

I have an odd problem; When I connect with my vpn with pptp, I can ping to all my windows server (only at IP, can't get my dns names working but that's not the problem.) The problem is that I can't ping to my Ubuntu webserver (also on IP).
When I connect locally, I can ping every machine in my network.

This the config:
- monowall as pptp server.
- local lan range 192.168.2.0-200
- pptp server 192.168.2.215
- remote range 192.168.3.0/28
- windows servers: 192.168.2.1 - 2 - 6
- ubuntu server: 192.168.2.3 - 4
- firewall rules, all open

Am I missing something? Or can anyone shed a little light what I'm doing wrong?

ps: it's not only ping, i want to use my vpn for a ssh connection to my webserver.

Thanks for all the reply's
