| Which sums it up pretty accurately, I suspect.  If the firewall has an 
| external IP x.y.z.49, then it will handle traffic to that IP.  If the MX 
| (or your telnet test) points to x.y.z.34, then the upstream router will 
| be looking for something that responds to _that_ IP.  If it cannot find 
| anything using that IP, then there is no route.

Hm... A logical error, in other words. *must* *get* *sleep* *now*...
Somehow I thought that the firewall would notice the connection attempt
from the router, and would be able to redirect the query from there.

| Presuming that x.y.z 
| are the same in both cases, you may get the results you want with:
| 
| ifconfig eth0:1 add x.y.z.34

I have it working now, thanks to you :)
