hi hope someone can help me out here as i am stuck with this one basically i want to use windows 2003 as a software router i have 2 nic on the server they have been given these ip addresses the first one has a ip address of 192.168.2.100 255.255.255.0 192.168.2.1 this is the default gateway connected to te internet the second is 192.168.1.100 with the same subnet mask and no default gateway so i then configed the dchp server on te 192.168.2.0 network with 2 scopes and set up a dchp relay on the other card to cut a long story short pcs on the 192.168.2 network can connect to te intermet fine but not on the 192.168.1 network i have a scope on the 192.168.1 network as follows 192.168.1.20 to 192.168.1.40 subnet mask of 255.255.255.0 default gateway is 192.168.1.100 what am i missing to get these acess to the internet

The problem is most likely due to the fact that you have not created a route to 192.168.1.x network on your Internet connected router. What happens is that the packets are leaving the 192.168.1.x network, the 2003 router will pass it on to the Internet Router (192.168.2.1), NATs it, then the Internet router sends it off. However, when the packet returns, it un-NATs, but doesnt know how to send the packet back to the 192.168.1.x network. On your Internet router, you have to create a route to the 192.168.1.x network. The interface where you have to send those packets to will be 192.168.2.100. That will fix your issue. IF you are unable to create the route, you will have to set up the 2003 server to do NAT'ing as well so that every packet that leaves from the 192.168.1.x network will be stampted as 192.168.2.100 as a source packet. Double NAT'ing works but the design is not as nice and it will break the communication flow between your 192.168.2.x and 192.168.1.x nodes. Visit: anITKB.com, an IT Knowledge Base.

Hi kkoolkev, Thanks for post here. According you description I understand that you want Hosts where located in 192.168.1.0/24 segment also could access internet through router 192.168.2.1. If I misunderstand please let me know. Hosts(192.168.1.0/24)--------------windows server 2003------------Hosts(192.168.2.0/24)----------------Router(192.168.2.1)-----------Internet Seems there is no problem that the hosts where in 192.168.2.0/24 segment access internet with point 192.168.2.1 as default gateway ,and is there any problem that hosts in 192.168.1.0/24 access hosts where in 192.168.2.0/24? What I think that you should enable route feature and add a default gateway on this windows server 2003 host ,please install RRAS on server and add the route below on it : Network Destination Netmask Gateway Interface 0.0.0.0 0.0.0.0 192.168.2.1 192.168.2.100 How to Use Static Routes with Routing and Remote Access Service http://support.microsoft.com/kb/178993 Hope that’s helps.

As I posted above, keep in mind that the Internet Router has to also know about the 192.168.1.x network. If it doesnt have a route (as I posted above), the packets will not be able to make it back to the 2003 RRAS server. This user needs a route on the router pointing back to 192.168.1.x network by sending the packets to the 192.168.2.100 interface (from the perspective of the internet router).
