I had to power cycle my Comcast modem, I didn't set a Mac though on the
monowall.  I just unplugged the modem for about 2-3minutes and then
booted it back up.  For some reason just unplugging and re-plugging
doesn't work, you have to let it sit unpowered for a few minutes for it
to flush its old Mac Records...  you tried doing a traceroute out to an
IP to see where its stalling out?  Is monowall even getting too the
modem or is it stalling from the modem to its gateway?

Wow Jim, I'm aware of all that. The "big-I-Internet" huh?
MAC address has been cloned (stated earlier)
m0n0wall WAN:
m0n0wall LAN:
Cable modem: not sure - does it even get an address? SB5100 has a status
page at, but I'm not able to browse that when it is on the
outside edge of the m0n0wall.
Browsing the cable modem (without m0n0wall) never indicates it has an
IP. Just signal strength & MAC addresses are listed. Strange that I can
browse it when it is on the outside edge of the DLink. Thought I may
need to setup a static route to it, but then the IP assigned to the WAN
interface is DHCP, so I can't create a route to it.
I use the LAN IP of the m0n0wall for default gateway (on the PC). It is
after all the router to get off the LAN. Default gateway the m0n0wall
receives from Comcast:

Until m0n0 can ping hosts on the big-I-Internet, you'll have no luck 
getting out from 'behind' the NAT
in m0n0wall.

What IP address/netmask does m0n0wall get via DHCP?

What is the IP address/mask of your LAN (or OPTn) interface?

What is the IP address/mask of your cable modem? (Does this match 
your default route?)

You might need to clone the MAC address of your notebook on the WAN
