[pptp-server] pptpd 1.1.2 no Inter-client connection?

[Andreas Henschel]

Hi everyone...

i'm new to this, so maybe this oproblem has been solved alerady:
I set up pptpd 1.1.2 on a Suse 7.1 Linux machine according to the HOWTO. I'm
able to connect multiple clients (in the local LAN) to the VPN-server, each
client can ping the server but none of the clients can ping another client.
What's wrong?

Thanks
