[geeks] setting up modem/router for sshd

[William S.]

I am currently connected to the internet via an
ISDN/ADSL Alcatel modem. It is currently acting as
a router (gateway '10.0.0.138') for my single pc
(10.0.0.150). I also have a static ip address
which is (213.84.66.123).

I would like to set up sshd on my pc so that I can
log into it from the outside. The only problem I seem
to have is that any attempts to log into 213.84.66.123
with ssh goes to my router/modem, not the pc with sshd
running. I kinda verified this using telnet 213... :
was directed to the modem/router.

I guess what I need to do is make the proper entry(s)
in my ip address/route table so that packets sent to
213.84.66.123 port 22 go to my pc, not the modem.

Below is a copy of my tables that are programmed into the
modem. I can change the entries via a web interface.
Can anyone tell me what I need to change to make it
work?
