Linux Wireless Printer NAT Problem

By normhaga ·
Currently my business network uses wireless only for printers and scanners. I have one machine that has Ubuntu 7.1 on it. I have one printer, a Brother HL-4070CDW that I can not access via the network unless I disconnect from the lan and connect to the wlan.

The addressing to the wireless router from the computer is something like this: 110.10.200.25 (local computer) -> 110.10.200.0,255 (lan router) -> 192.168.0.0 (wireless router) -> 192.168.0.65 (printer). The addresses have been changed but are representatively correct. The printer works with other Linux and XP installs in this configuration and the printer is only connected to the network via wireless. The wireless is encrypted using WPA and tkip.

I am using the Cups Printer driver and had to force architectures with the Brother drivers. This machine has VMWare installed which virtualizes XP and Mac OS X and uses DHCP for the virtual machines. The virtual machines mostly seem to be assigned to the 192.xxx.xxx.xxx/16 range

Does anyone have an idea as to why I can not connect to this printer from the lan routing to the wireless, and have to actually connect to the wlan to use the printer from this machine? Other Linux installs using OpenSuSE, Debian and SlackWare do not exhibit this translation problem, nor does the sole Windows box.
