I have a problem with RRAS using a Linksys Wag 300N router

Current Set-up

As required by windows server 2003 when setting up NAT I have two NIC cards on my Dell 2600 server with different subnets. My server’s current set-up is as follows:


1st NIC Card – Connected to Router (Internet Connection)

IP address: 192.168.1.10 (server)
Gateway: 192.168.1.1 (Routers IP Address)
DNS: 192.168.1.10 (server)

2nd NIC Card – Connected to LAN

IP Address 192.168.16.1
Gateway 0.0.0.0
DNS 192.168.16.1

The issue is with DHCP, when I attempt to allocate IP addresses dynamically it does not work. I attempted to set up a DHCP Relay within RRAS and although the DHCP server was receiving the requests and it allocated the client computers with IP addresses, the client computers did not actually receive them.

NOTE: the DHCP was issuing the IP of the LAN (192.168.168.xx) as stated above.

I am assuming that this is because the linksysy router is not sending the DHCP packets to the client computers and I am not sure how o resolve this issue.

However, if I provide a static IP address to client computers for example:

Static IP: 192.168.16.201
Gateway: 192.168.16.1
DNS: 192.168.16.1
Then all works well and the computers can connect to the Internet and the shared devices on the network.

Can anyone help on this matter.

The linksys isn't going to hand out DHCP addresses to 2 different subnets. Do you really need the second NIC and subnet? It would be a lot easier if you disable the second NIC. If you don't want to do that, then use static IP addresses. I like them better, myself.

I think the confusion here is the idea of using rras dhcp for the lan segment. This is incorrect since this is for remote client access which your lan segment is not. You want to use the regular dhcp server in 2003 to assign ips to your workstations on the x.x.16.x subnet

'tis the season to be of good cheer. Wishing one and all happy times with family and friends.
