[wellylug] Routing problem

Hi all,

I have a wee routing problem.  At least I think it is a routing problem, 
it could be a 'stoopid Ian' problem, but I am going with the routing 
problem for now.

I have a network.  In that network is a machine (let's call it 'ubuntu')
with an IP address of 10.129.128.13 (ah yes the lucky one), a subnetmask 
of 255.255.252.0 and a default gateway of 10.129.128.1.  That default 
gateway takes me to the other subnets of the network without any problems.

I'm playing with NoMachine at the moment, trying to find better ways for 
staff with broadband connections at home to use them to connect to our 
terminal servers.  So what I'm trying to do is get an external ssh 
session to come through the ipcop firewall (10.129.128.3) to 'ubuntu'.

It doesn't seem to work when the default gateway of 'ubuntu' is 
10.129.128.1.

If I change the default gateway on 'ubuntu' to 10.129.128.3 it works 
well, but I can't see the rest of my network subnets.  Which for external 
connections is fine, but if we start using it more regularly it'll be a 
problem.

For consistancy's sake, I would like to the default gateway to be the 
10.129.128.1, but how do I also get a 'second default gateway' or at 
least an intelligent route to the outside world?

Cheers muchly in advance,

Ian
