2nd subnet 192.168.1.0 has ADSL router [LAN IP 192.168.1.1]and is D. Gateway to web server. I want to administer the 2nd subnet from 1st subnet 172.18.250.0 through [LAN IP 172.18.250.3] Linksys RVS4000 Firewall/Router [WAN IP 192.168.1.254]. X-over cable from FW/Rtr WAN port to LAN port on ADSL. I can ping to FW/Rtr from 1st subnet & can ping 192.168.1.254 from 2nd subnet, but no ping from 1st subnet to 2nd subnet. What am I missing?
