Ok, I’m working on this right now. I will go through your receipe and comment/edit the article as I find stuff.

My setup is WRT54G-TM
Dynamic WAN ip address (fake) 200.128.3.123
locked to the MAC address of whatever is on the
end of the wire.
WAN is a /24 with x.1 gateway
routed (fake) 70.100.6.144/28

email me and I’ll send you an edited word doc of your article
so it’s a little closer to publications in the WIKI

BTW, port 520 is RIP, it is blocked so that internal
routing info is not available to snoopers.

Best regards,
Michael
