For a site to site VPN you need to have RRAS servers at both ends of the
link. Each RRAS server has a demand-dial interface configured and there is a subnet route for the "other" site associated with each demand-dial interface. The "calling" router must use the name of the demand-dial interface on the "answering" router as its username when connecting. This binds the connection to the dd interface and activates the subnet route. When the VPN connects correctly, each RRAS router has a subnet route to the "other" site through the VPN. If each RRAS router is the default gateway for its local LAN, the site to site link now works. If the default gateway is the Linksys, you still have work to do. You need to get the private traffic to the RRAS router before it tries to cross the Internet. If you don't it has not been encrypted and encapsulated. It still has a private IP and is discarded. The way to fix that is to add a static route to the Linksys to bounce the private subnet of the "other" site to the RRAS router. The RRAS router will then encrypt and encapsulate the traffic before sending it back to the gateway router. It now has a public IP header and can be sent across the Internet to the other site.

Thank you very much for your response. I still am not able to get it to
work. I even made a couple changes to see if it will work. I added a second NIC to the server. Then I configured NAT and VPN on the server. I still am using the Linksys router as it is connected to the public side of the NAT. Right now I don't care if the remote end can communicate to my end. I created the demand dial interface on my server. Here is the following diagram; 192.168.0.x dg 192.168.0.7 | RRAS 192.168.0.7 Private Interface dg 192.168.0.7 Has a static route added by default by the New Demand Dial wizard 10.10.0.0 mask 255.255.255.0 using the Demand Dial Interface | 10.100.0.2 Public Interface dg 10.100.0.1 | 10.100.0.1 Linksys Firewall | Internet | 10.10.0.1 Firewall Linksys | RRAS 10.10.0.2 dg 10.10.0.1 | 10.10.0.x dg 10.10.0.1 The VPN connects successfully and only the server can ping all IP's on remote end. The only IP the client can ping is the address that is assigned to the server by the remote VPN server. Any ideas would be greatly appreciated. Thank you very much.

Why would you add a second NIC or install NAT? That makes things worse,
not better. Your Linksys is already doing all of that. Get rid of both of those then read my post again.

It was a Microsoft MVP suggestion. I finally got it working. Needless to
say the Microsoft MVP didn't know what he was talking about. Thanks for all your help. Is there a way to force a VPN connection to use a specific NIC, or am I stuck with the NIC that is the VPN server? Have a great weekend.

Glad to hear you got it working. What exactly do you mean by "use a
specific NIC?" A VPN connection does not really connect to any NIC. The VPN connection terminates at the internal interface for a client-server or "dialup" type connection and at the demand-dial interface for a router to router connection.

Thnak you again for replying. What I would like to do is have multiple
NIC's on the VPN deman dial server. Then have each NIC dedicated to different networks. Right now when I dial out with the VPN server, it always goes out the NIC that the server is using to surf the internet. The server right now has 3 NIC's each NIC with a static IP connected to the Linksys firewall. Is it possible with my current setup? Thanks.

No. The VPN traffic must go out through the default gateway. While it is
crossing the Internet, the VPN traffic is encrypted and encapsulated inside a packet with a registered public IP. There is no point in having multiple NICs in the server if they all connect to the Linksys. The system will only use one of them. You can only have one default gateway, even if the NICs were connected to different routers. <(E-Mail Removed)> wrote in message news:%(E-Mail Removed)... > Thnak you again for replying.

What other networks do you need to connect to? Do you want to reach them
by VPN? You can configure more than one site to site VPN connection on the server. You set up a new demand-dial interface and configure a new site to site connection using a different subnet route. The traffic still all goes out through the default gateway. But the encapsulated packets now have the public IP of the VPN server at the second site on the front.

Thank for all the information. It answers all my questions. I sort of
wanted to keep it clean, and have different VPN's using different NIC's. But I guess I can't as it is going to use different gateways. Thank you very much and have a great week.
