The only information I've found regarding firewalls use with an Allstarlink.org server is with respect to a router and port forwarding. In the ACID build, the firewall seems to only address TCP for SSH, and not the UDP. Is the assumption here that all Allsterlink.org servers will be behind a firewall such as with a router? What about protection when the server is on a public IP address, statically set, without a router? What protection is afforded here? Is it then necessary to setup the ACID firewall with "Other ports" using "222:TCP 4569:UDP"? I only see "SSH" in the Allow incoming: section, and should eth0 be unchecked? Thanks, r/Bob kk6ecm
