Our remote site has office LAN 192.168.2.x with gateway 192.168.2.1. We have added an extra connection to that remote site in order to have a dedicated link to a database server (IP 192.168.2.16). Installed was Cisco router 17xx series using BGP and Frame Relay. We connected a router to remote site's LAN via FastEthernet port and gave it an IP address 192.168.2.4. How do I make that database server (running Win2000) recognise 192.168.2.4 as an additional gateway, so we can connect to it without disturbing its current 192.168.2.1 gateway connectivity? It works if we specify a new gateway address in server's TCP/IP config, but this involves downtime and we cannot afford that.
I tried adding a route to server with "route add 192.168.2.4 255.255.255.0", but it didn't work. Any hints?
