one routing question

[ESGLinux]

Hello All,

finally I have found the solution to my problem in this page:
http://linux-ip.net/html/adv-multi-internet.html

<http://linux-ip.net/html/adv-multi-internet.html>Basically the solution is
to add a new ip to the server an make the routing based on this ip.

Greetings and thanks for your help
