server cant connect to internet with RRAS on

When I turn on Routing and remote access and try to configure it the server can no longer connect to the internet. Is this normal? do I have some setting that is wrong?
thanks

Can't Ping External Network Adapter After Configuring RRAS as a VPN Server

SYMPTOMS: After you configure the RRAS as a virtual private network (VPN) server in Windows 2000 Server with two or more network adapters, pinging the external network adapter does not work. Or you get destination not reachable if you ping other computers from the VPN server. This behavior occurs only while RRAS is running. Pinging the external network adapter succeeds when RRAS is stopped.
RESOLUTION: When you use the Routing and Remote Access Server Setup Wizard to configure RRAS as a VPN server, Input and Output filters are automatically configured on the external network adapter to process only VPN traffic and disable all ports and protocols except protocol 47 (GRE), TCP port 1723 for PPTP Outbound/Inbound, UDP 500 for ISAKMP and UDP 1701 for L2TP. Refer to case RL060204

Thanks Robert,
Can you tell me how to configure the filters so that all traffic is not blocked. I am behind a hardware firewall and would like to be able to access the internet with the server and all of its clients.
thanks again
Adam

Hello,
Sorry I wrote this before researching your website and i found the answer to the question I just asked. However I do have a new question. What should I filter? I basically used 'any' for the input an output filter which is basically leaving it wide open. But thats what I had to to so i could get online to write this.
I would like my server and all clients to be able to brows the internet, play online games use email and the server might even host a website soon.
thanks
