Research direction

Start with the reported /opt/bin/sshuttle --method auto --firewall entry point and reproduce the failure on the environment using iptables v1.3.7. Trace the firewall setup that invokes the addrtype match and compare the available iptables capabilities. Done means the tunnel can start and cleanup completes without the reported fatal error.
