browsing thru two local area network

hi,

here is the scenario, for example i have a local area network connected to the internet via dsl modem and it has a router/firewall. and then i have another network but unlike the first one it is not connected to the internet in any way. it isjust a file/printer sharing network. is there anyway that a workstation on the first network(the one that has internet) also view the second network’s shared files and devices?

thanks in advance…
