I have configured server 2003 as router using RIP by RRAS.It work fine & i can can route the packets from one network segment to another. Well i want to do static routing in my test lab .For that purpose i enable RRAS & choose Router.New Static Route. The following information will be necessary to add a static route: Interface Destination (Network) Network Mask Gateway (address) Metric In interface i have two Lan cards LAN1 is 192.168.1.201 LAN2 is 15.15.15.15 I choose LAN1 ,please just guide me that what IP should i give to Destination, Network Mask, Gateway. These things are confusing me.

LAN1 has a standard network mask for class c networks (255.255.255.0). LAN2 The IP of LAN2 should be one of the destination network, otherwise, you need to add another standard gateway to the destination network. The network mask for LAN2 depends on how many clients should be used in LAN2. You simply can use network mask 255.255.255.0 to have 253 clients in the destination network. Please send a reply, if you solved the problem !!!

255.255.255.0=0-255=1-254=254 hosts Don't you hate typos :-)

Oh yes, right ! I do hate typos :-) Please send a reply, if you solved the problem !!!

well i am using 255.255.255.0 subnet mask.A very simple network.The windows 2003 is inbetwen these two places.Just like u make a test lab for testing ststic routing. I am unable to understand that in the gateway which IP address should i write? suppouse i gave Interface LAN1 Destination (Network) 15.15.15.1 Network Mask 255.255.255.0 Gateway (address) ? Metric 1 please guide me .

It doesn't need a gateway address, if you only want to communicate with 15.15.15.0/24 network, because the server is part of that network and is aware of the direction. You only need a gateway, if the address, you want to connect to is not known in the current network. E.g.: If you simply want to surf the internet for www.google.com, the address isn't reachable from your private network and did not know, where to find google.com. In this case, your local computer is configured to forward the request to your router. The Router is connected to you ISP. The router itself has no idea, where to find google.com and uses it's standard gateway (your ISP) and forwards the request to your ISP. Your ISP sends the answer on where to find google.com back to your router. Your router forwards the reply of the ISP to your local computer and you can surf to google.com. Again: If your computer has the IP address 192.168.1.100 and you will want to connect to another computer in that network, e.g. 192.168.1.101, you'll never need a gateway for that. But you will need a gateway to access a computer in the network 15.15.15.0. The gateway address for a computer of the 192.168.1.100 is 192.168.1.201, to access a computer in network 15.15.15.0. If a computer of the network 15.15.15.0/24 needs to access a computer in 192.168.1.0/24, the gateway for that computer must be 15.15.15.15. Please send a reply, if you solved the problem !!!

well thanks "paulsep" for your detail reply. I have tried according to your direction & iam successfull to use windows 2003 as a static router but these is one thing confusing me . I am again writing the configration so it may belp you for guide me in much batter way. Server LAN1 IP:192.168.1.201 Subnet Maske :255.255.255.0 Server LAN2 IP:15.15.15.15 Subnet Maske :255.0.0.0 Client1 IP: 192.168.1.200 subnet mask : 255.255.255.0 Default Gateway:192.168.1.201 Client2 IP: 15.15.15.200 subnet mask : 255.0.0.0 Default Gateway:15.15.15.15 well these were my client & server settings now in my server Static routing settings are Interface LAN1 (This is 192.168.1.201 Lan card) Destination :15.15.15.200 Network Mask 255.25.255.255 Default Gateway: 15.15.15.15 Interface LAN2 (This is 15.15.15.15 Lan card) Destination :192.168.1.0 Network Mask 255.255.255.0 Default Gateway: 192.168.1.201 My problem is in LAN 1 after writing destination which is 15.15.15.200 in the Networkmask it does't accept 255.0.0.0 and give a message i.e "The Network Mask entered is not valid.The destination address can not be more specific than the network mask". and if i write as 255.255.255.0 it accept it & i can ping my both sides network. The purpose to write all my configration is to view & guide me that why it is not accpting the valid subnetmask in server static ip configration? thanks in advance for your help.
