If you don't have to use/setup PPPoE to use the dsl connection, then it's a
router (just dhcp needed). If you don't know what PPPoE is, and you used
your PC to the dsl modem fine before, and didn't install any software (on
your PC), then it's a dsl/router combo. This is quite common for dsl
providers because then you don't have to setup PPPoE at all
(authentication).
Since you have a dsl modem/router, it almost certainly uses NAT. Since it
uses that, you have to forward port 22 to the IP of the Gentoo box. Check
out the make/model and go to the manufacturer's website to find instructions
on how to change the settings; however, most of the time you can type in
your gateway IP in your web browser to get to the settings. Sometimes the
page is passworded, sometimes it isn't. Judging from the IP you mentioned (
192.168.1.47), it sounds like you have a Linksys dsl/router (although I'm
not aware they made dsl/router combo boxes, only cable modem/router combo
boxes).
I've set up ssh port forwarding from my Westell modem/router to my
Gentoo router via port 22 and TCP, but when I try to ssh in from my
laptop using the modem's global IP address I get "Connection refused".
I've disabled the Westell's firewall. The Gentoo router's firewall
was configured according to:
http://www.gentoo.org/doc/en/home-router-howto.xml
which includes:
(Optional) Allow access to our ssh server from the WAN
# iptables -A INPUT -p TCP --dport ssh -i ${WAN} -j ACCEPT
What could be the problem?
Also, this thing was supposed to be just a modem and I'd like it to
behave that way as much as possible so my Gentoo router can handle as
many of the router duties as possible. I've disabled the Westell's
firewall. What other types of things should I look for in the
Westell's configuration screen to disable? Is there anything that
might prevent this modem/router from behaving like a modem for all
intents and purposes so my Gentoo router can behave like a router
connected to a modem?
