Wireless file/print sharing behind server

diagram on current config:
IP 66.184.84.xxx --> LINKSYS Wireless router WRT54G (LAN SIDE 192.168.2.1) -->(192.168.2.101) Dell Poweredge2900 Windows SBServer2003 (192.168.1.101) --> 24 Port Switch --> 24 Port Switch

My problem is that users who connect via the wireless router have internet access but cannot access files/printers behind the server ie on the switches. The end objective is to be able to VPN from outside the office and have file/print access, however, the current mission is to ensure access for in office wireless users. Any help including suggestions as to inexpensive VPN solution would be appreciated. Thanks

 

assuming the net mask of 255.255.255.0. The file server is on another network. Windows SBServer2003 (192.168.1.101
Put it in the 192.168.2. network and see what happens

nnn.nnn.nnn.hhh
255.255.255.0
n= network
h= hosts

Also there is an open vpn - google it
