VPN & Web Server

I left the default gateway blank in the LAN TCP/IP
properties, but now the web server is not visible on the
Internet nor can Exchange Web Access be used now. The LAN
adapter connects to a router with a public IP address and
ports 80 and 25 are open for HTTP and SMTP. The VPN
server is working now since I made the second network
adapter have a public IP and default gateway. The second
network adapter doesn't connect to the router, it's out on
its own. My question is, how can I make all of these work
together? If I try to put the VPN connections back on the
first adapter, which connects through the router, then the
VPN will not work again. Any ideas on this would be
greatly appreciated. Thank you.

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. 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. To allow pinging to and from the external network adapter, add Inbound
and Outbound filters to the adapter to allow ICMP packets to be processed on
the adapter. To do this, go to Routing and Remote Access>Server Name>IP
Routing>General, In the right pane, right-click the adapter that has been
configured as the external adapter, and then click Properties>Input
Filters>Add, In the Protocol box, click ICMP. Do the same on Output
Filters.
