Original GitHub issue: https://github.com/debauchee/barrier/issues/348

Operating Systems

I'm using Ubuntu 18.10 and ferenOS (bionic beaver)

Barrier Version

2.2.0

Steps to reproduce bug

I activated the UFW firewall and allowed port 22 for ssh. Barrier now fails to communicate across my four laptops. When UFW is disabled, Barrier is back in business. How do I keep firewall and Barrier operating at the same time?

Cheers

Snerken

Did you open the port barrier/synergy use? (Port 24800)

That did the trick.

Merci bien
