CUPS question with two subnets

[Dave Reed]

On my wired network 192.168.1.x, CUPS seems to work fine and all
computers can find the printers hooked up 192.168.1.5.

I have a wireless router that has an "external address" of
192.168.1.128 and an internal address of 192.168.2.1. My wireless
laptop at 192.168.2.2 cannot find the printers on 192.168.1.5.

On the laptop, I put: BrowsePoll 192.168.1.5:631 in
/etc/cups/cupsd.conf 

but it complains in /var/log/cups/error_log

E [14/Apr/2004:16:54:07 -0400] [cups-polld 192.168.1.5:631]
get-printers failed: server-error-service-unavailable
E [14/Apr/2004:16:54:07 -0400] [cups-polld 192.168.1.5:631]
get-classes failed: server-error-service-unavailable

Any ideas?

Thanks,
Dave
