All packets are routed according to the routing table of the host at each step of the way. This issue commonly comes up when people install a Shorewall firewall parallel to an existing gateway and try to use DNAT through Shorewall without changing the default gateway of the system receiving the forwarded requests. Shorewall reads those configuration files and with the help of the iptables utility, Shorewall configures Netfilter to match your requirements.

Security-Enhanced Linux secures the shorewall processes via flexible mandatory access control. The shorewall processes execute with the shorewall_t SELinux type.
