Shorewall also sets network system parameters such as arp filtering,
ip routing, etc.
So this could be a "Shorewall issue" because Shorewall changes some of
these network parameters. It also handles routing tables and routing
rules.

In any case, you describe a general situation, but I'm giving details
on a very specific issue.
I appreciate your time, but I need to figure out why I'm seeing this
odd behavior.

Since you do not seem to be using Shorewall but iptables and system
tools, I was wondering if you could share the name of a could "general
purpose" Linux networking forum or mailing list. I once subscribed to
the netfilter ML, but it was overwhelming.
If you have any suggestions as to where I might explain the issue I'm
seeing in this topic, I'd appreciate it.

Thanks,
