Wouldn't it be possible to REDIRect the traffic onto your firewall

machine to some other port just in order to record its contents? So you

don't really open up the port to the other machine again.





Not sure how to REDIRECT. If I have a second IP on my interface with IP
192.168.11.1 would I:

REDIRECT $FW 192.168.11.1 tcp * - 97.107.134.150



... and then listen on 192.168.11.1 with Wireshark? Would it actually
see any traffic?

I would try the following



in your shorewall/rules



-----8<---------



DNAT    net     loc:192.168.11.1:3333   tcp     3333

DNAT    net     loc:192.168.11.1:3333   udp     3333



------8<---------

And then try



tcpdump port 3333 -i <your_dsl_if> -vv -A
