Test PPTPD

[Venneman]

QUESTION: How can I test my PPTPD connection?

SITUATION:
SERVER: Installed pptpd_1.1.2 (Debian kernel), works fine
I think, no errors.

CLIENT: Windows 2000 prof., VPN setup to server, works fine, can make a connection.

client and server connected peer to peer (only for the test)

Client ip 192.168.1.3
Server ip 192.168.1.2

ifconfig ppp0 (Server side)
10.0.1.1 (=ip from range defined in config)

ipconfig ppp0 (VPN connection, Client side)
192.168.1.2

Is it normal that I see the ip addresses or is something wrong. Is my connection setup right, and how can I test it.

I'm new to VPN and I intend to use it for VoIP to avoid NAT problems.

Thanks,

Wim
