Routing VNC Traffic

I need to set up a vnc connection on a network. There is a central DSL modem which provides DHCP where applicable to the computer which I want to use to view the server- this machine has IP static address 192.168.1.7. The actual machine which I want to view is on  a different subnet and if set to DHCP gets it IP from a Linksys  Wireless/ethernet router - preferred IP scheme is 192.168.10.55.

I can ping 192.168.1.7 from 192.168.10.55 only using the IP addresses. I cannot see the other machine using VNC.

Before the Linksys was put in the VNC worked fine.

Any idea how I can get this to work?

dhcp disable in linksys, and don't use wan port.  That's all..

just a guess here because you didn't provide enough information about the topology or the new linksys device but have you tried setting up port forwarding?
in most older linksys residential gateways you would get to this by clicking on the advanced tab and then you would see a port forwarding tab
in many of the newer routers there is an applications & gaming tab
you will want to forward the vnc ports (depending on vnc version there may be more than one but the default is 5800) to the ip address of the machine behind the router
now when i say behind the router i mean you have plugged your internet port into the preexisting network and anything connected to the ports labeled 1-4 on the back of the router or if it has wireless and wireless client
in most cases you will also want to make sure that the machine you are forwarding the port too has a manually configured address and is not using dhcp so the port forwarding will not need to be updated every time the target gets a new ip address

The Linksys had to be set to router mode and static routes assigned on both routers
