I've setup a Cisco 2514 running 2 Ether networks. I can ping from both to both, connect to one domain and share all data and peripherals.
My problem is that as soon as I connect to the internet, I loose all comms between networks although computers on the same network can still communicate. Seems that the router just stops routing.
My internet connection is an ADSL running on a WinXP(SP2) PC. Whether I share the connection or not OR turn off the XP firewall or not, the symptoms are the same.
Any help appreciated.
