[sdnog] configure outgoing configuration based on incoming ports

[Samir S. Omer]

Hi all 

I'm configuring a Linux CentOS machine with multiple virtual IPs to run a squid service listening on different ports. 
how can I bind requests coming for each port to go through specific IP ? 

for example requests coming to port 8081 to go out with the IP 192.168.1.1 and requests coming through port 8082 goes out with IP 192.168.1.2

incoming -> Squid -> Outgoing
*:8081   -> Squid -> 192.168.1.1:80
*:8082   -> Squid -> 192.168.1.2:80

Regards
