QUESTION How do I allow registrations from separate subnet?

[Sean Hunter]

It's all in the title, folks!

I've a server install on network 192.168.1.0/24 and clients on 192.168.2.0/24 and I want to make them talk to each other.

I might be missing something here but could you change the broadcast mask to 255.255.254.0?

A mask of 254 would give you
11111111.11111111.11111110.00000000
But allows 192.168.2.0 won't allow 192.168.3.0

A mask of 255.255.252.0
equates to 11111111.11111111.11111100.00000000
The third octet allows the use of 0, 01, 02, and 03 for your lan network, instead of them being in separate subnets. Its easier if they are not separate subnets and removing that part of the mask achieves this by t using a mask such as
255.255.0.0 which saves you calculating which bits you need for your requirement and allows you to use anything in the 3rd and 4th octets from 1 to 254.

Thought I should post an update: I had set those settings via the GUI. Turns out my issue was mostly unrelated to PBXinaFlash; my RPi had decided independently to associate with a nearby open WiFi network. I managed to disable the network, but I'm still not sure why Raspbian is going around promiscuously associating with any nearby WiFi network that it can find. On top of that, even once the network was offline, the default route remained in the routing table, royally screwing my attempts to register outside of that broadcast domain.

Many thanks to the above posters for taking the time to help me. Maybe NV should consider offering a 'disable wireless' option in the setup menu?
