Re: [Sheflug] Remote Access

Hi Darrell

I refer you to my first post on this.

<><><><><>
I have port 22 forwarded to an internal machine which I can then use to
ssh locally to any machine on my LAN.  Is this a possibility for you? 
Else you'll have to do something more sophisticated passively I guess.
<><><><><>

So, what you need to do is 'port-forward' the port you want to use to
your local machine.

If your Blueyonder IP is 22.33.44.55 and the machine you run ssh on (for
eg) is on 192.168.1.8 (as is my server - ooo security leak!!! :D) then
you will have to port forward 22.33.44.55:22 > 192.168.1.8:22 

You can in fact map ports onto a different port for added security.  But
anyhoo, I used to use a linux box as my gateway/router and configured IP
tables to do this for me.  Here is a handy snippet.

iptables -t nat -A PREROUTING -i ppp0 -p -tcp --dport xx -j DNAT --to
aa.bb.cc.dd:xx

Where xx is the port your mapping and aa.bb.cc.dd:xx is the local
(internal) IP + port you're mapping to.

Now, I've gone down the James Mears' route (ahem) and I use the SMC
Barricade hardware modem/router/teasmade and there I configure it to do
something similar although it calls it virtual servers or something.

Anyhoo, without anymore detailed info I'm afraid I can't help
anymore.... and perhaps I couldn't anyways :)
