[DeleGate-En] Re: Use the same outgoing IP address as the incoming IP address
30 Jul 2008 21:23:16 GMT Sorin Esanu <>

Those 3 ips have different routes to world wide internet. So the 
application program does not have to select anything in respect to 
routes to destination servers. This is done by the hardware that route 
those ip addresses.
Anyway, I am aware that I can start 3 different DeleGate with different 
SRCIF, but that is waist of resources. What if I have 100 ips and I want 
to do that...
All I need is a simple way of telling DeleGate to automatically use to 
connect to final destination the ip that the original request came on. I 
need to keep things apart, but with the minimum effort...
