Yes, I have examined the tcpdump of both gateways. I know that the
packets are able to leave the gateway machine that is doing the
"smbclient -L IP_ADDRESS" request, because I setup a samba server on
another linux box with an external IP (209.123.xxx.xxx), and from the
machine behind the gateway (192.168.20.20), I was able to issue the
command "smbclient -L 209.123.xxx.xxx", and I got results. It listed all
the shares available instead of just failing. That external linux box,
has only a minimal firewall which allows the appropriate traffic. I
"think" this works because my firewall on the gateway allows any
connection that originated from inside it's private subnet.
I am able to repeat the above test on the other gateway as well. They
both have the exact same firewall configs.

So, I "think" that I am missing a forwarding rule, or I added a wrong
rule somewheres. I'm lost.
