Hi Simon,

Thanx for the help


The ADSL connected server currently runs on 196.210.176.x, and the
internet connected server runs on 196.34.136.109

So, there's not on the same subnets, by a mile. In fact, the 2 servers
are seperated by about 30Km's, but I can get into both via the
interner.

Would ipforwarding still work, since I want to reroute all packets on
eth0 of 196.34.136.109 in, and back out?

Open vpn is a nice solution in my opinion

Mark,

We, in South Africa sit with a huge problem in that our clients can't
connect to the rest of the world cause SEACOM is down. i.e. our client
can, for the past 3 days, only surf local (i.e. local in South Africa)
websites, email, etc. We have a lot of client's servers hosted in the
USA, so they can't reach their websites or email and business is
standing still for them.


So, I want to reroute all their traffic via one of our other servers
which right now has got full internet access, as such:


<ADSL client> - <Limited internet> - <server> - <full internet>


I already setup squid for this and it works great, but doesn't proxy
SMTP / POP3 / Skype / IM / RDP / etc etc. And I don't want to setup a
proxy service for evey service imaginible.

I don't know, since I've never setup one

The trickey part, which I don't understand, is how will this work.


i.e. I SSH into ADSL client's machine, and setup the VPN. The VPN then
connects to our linux server which now acts as gateway. How do I tell
the client's linux server to rout all traffic (apart from my SSH
connection, otherwise I get cut-off) via the VPN, and not via the same
ADSL line on top of which the VPN runs?
