Open Firewall Ports

List of required ports to be opened

In order to have all things working properly following ports should be opened on firewall:

1) 11228/udp 2) 11229/udp

If you are using ufw, there is snippet for this:

sudo ufw allow 11228,11229/udp

If you are using relayer separately on another host you should also open 11226/tcp on server with relayer

sudo ufw allow 11226/tcp

For a co-hosted setup, which is usual for most cases when validator and relayer are located on one server no 11226 should be opened. You must open only 11228/udp, 11229/udp for this.
