Shorewall configured as basic 2 interface router/firewall. New Ubuntu 20.04.1 server installation with shorewall 5.2.3.2. Ubuntu server current with all security patches and updates. Ubuntu server network configuration managed by netplan. Ubuntu server also running dhcp (isc-dhcp-server) server. Shorewall firewall seems to work, but router does not appear to route packets correctly. I can connect to the firewall via ssh via net and loc interfaces. ssh connections through firewall/router seem to work. DHCP server on loc interface is working correctly. HTTP connections, DNS connections, NTP connections through router are rejected.
I am using shorewall on 2 other existing systems without issues. Existing shorewall systems running Ubuntu 18.04/ or 20.04 servers and ifconfig to manage network interfaces (systems built using ubuntu 14.04 and upgrade via in place upgrades). See log file attached
