IP routing with 2 NICs
Posted on 1998-10-12
I have a WindowsNT server that I am trying to set up as an internet router. It has two NICs, one is connected to an internet router, address 192.168.4.128 mask 255.255.255.0 and the router's address (gateway) is 192.168.4.254. From the server, I can browse the web successfully and ping whatever I like.
The second NIC is set up with IP address 10.0.4.1 and connects to 30 clients with addresses in the range 10.0.4.2-250, supplied via DHCP from the server. The DHCP config supplies router address 10.0.4.1 as a gateway. I have also manually configured a client with IP address 10.0.4.2 and gateway address 10.0.4.1 mask 255.255.255.0.
RIP for Internet protocol is installed on the server, and SP3 is installed.
When I do a "route print" from the server, there is a line:
Network address netmask gateway interface metric
10.0.4.0 255.255.255.0 10.0.4.1 10.0.4.1 1
which from what I have read should allow the clients to access the rest of the world.
The problem I have is: I cannot ping the internet router (192.168.4.254) from any client on the 10.0.4.0 subnet, but I can ping the other NIC, ie:192.168.4.128, so none of the clients can access he web.
Each client and the server has NetBEUI and TCP/IP installed, and all the clients can see the server in network neighborhood
Please read this question carefully before giving any one-line stupid answers
