I have a few clients with this particular setup. The SMC router can quite
finicky and certain things can vary greatly with firmware. In most cases,
Comcast usually gives you a DHCP reservation, not a real static IP, so the
only way to get around the NAT that the SMC router forces on you is to put
m0n0 in the "DMZ".

I did run across 2 instances where they actually did give a static IP and I
was able to avoid the NAT nonsense, but I wouldn't expect it.

Other issues I encountered were PPTP issues (because some firmware versions
don't allow you to disable the SMC's built in PPTP server), and one
particular older firmware ( 2.11.14) that had a nasty habit of disabling its
own DMZ for no reason whatsoever, bringing down your VPN or whatever else
you might be serving. Save the settings (no changes necessary) and the
problem is fixed. I haven't seen that older firmware in a while so I
wouldn't worry too much about that.

In case you didn't know, the default IP LAN IP address for the SMC is, the default Username is "cusadmin" and that password is
"highspeed". If you want/need your firmware upgraded, you have to beg
Comcast to do it, because the SMC's UI doesn't allow you to.

I hope this helps,
