Hi everyone.
I've been using OpenVPN for home personal use for a while now (Server=Linux, Clients=Windows & Android) and it's been working great, except for one use case that I can't seem to nail down. My alarm system (Honeywell) has a piece of Android software that allows me to arm/disarm/etc when I'm on the same network. I'd love to be able to use this software remotely as well, when connected via OpenVPN. It seems the Android software uses a broadcast packet to discover the alarm panel. More specifically, when I decompiled the apk, I found that it does a UDP broadcast to 239.255.255.250 to do discovery. That being said, I imagine that if I was using OpenVPN in tap mode, there's a chance this might work. However, the official Android client doesn't allow tap, only tun.
Is there any way I can route the broadcast packets between the two networks? Any other ideas?
Thanks!
