I just realized that the config I sent through to the list didn't come
through as I typed it. Probably because the filter is set to take out
certain characters. Rizzo, hopefully you got the correct config in the
message I sent you directly.
Using the static command should work, provided that it's coupled with the
appropriate NAT command (to tell the router where to NAT and in what
direction) and the correct access-list command (needed to tell the router
to pass traffic from the particular public IP identified in the static
config).
In your particular case, you'll need to setup a static command and
access-list for each IP address in your modem pool.
Refer again to the URL I sent in the previous message. It has specific
configuration commands to do exactly what you're trying to do.
Thanks,
Craig
