[somewhat OT] connecting to a box behind a NAT router

[Rainer Mager]

Hi all,

	I'm about to get ADSL installed for my home Internet connection and have
chosen to do this via an ADSL router (as opposed to a modem). The router
will have a static/global IP address but everything behind it will be
connecting through the router via NAT. So, my question is, is there any way
to get into (telnet or ssh) my box behind the router from outside?
	Is there some sort of tunneling protocol/tool to do this? If so, what
happens if I want to connect two boxes is the same situation (behind NAT
routers)? Is is still possible? Is is interoperable with Windows and Linux?

	Any ideas would be greatly appreciated.


Thanks in advance,

--Rainer

Yes, it's possible :)
See the iptables man-page for that, and look for SNAT & DNAT. If you need
any help with your setup, I'd be happy to help.

Yes, if you use ssh+pppd you can such a thing. Standard routing, no, the
NAT make it unusable. What I would have done (as I do for my home
network, is make a linux router and use a standard *DSL modem. Much
better all around.

It depends on the router. I use a Linux router and port forwarding to accomplish
that.
