I have3 UBNT Lite 3’s at 3 locations with VPNs setup between them to allow me to link up their phone systems. I logged onto all of the routers and everything looks like it’s up and everything is matching. The only difference I can find between any of the programming is the Firmware versions, Site 1 has a V1.9.1 and Site 2 and 3 have V2.0.1. Site 1 works going out to sites 2 and 3. But I am unable to even ping either sites from 2 or 3. Site 2 said invalid ping data when I tried to ping the other VPN connected subnets, and site 3 wouldn’t give any feedback when trying to ping to site 1 or 2.
I’m sorry if this is confusing, I’m just starting to get more into VPN configuration and can give any more additional information if needed.
TIA!!
Edit: apparently the V2 has some bugs in it and reverting it back to a verified working firmware fixed the problem, didn’t even have to change any programming.
