4 nic advanced routing question

Linux Advanced Routing and Traffic Control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have scoured the net, gotten a few pointers from several people and looked at several books and still have not come up with a satisfactory solution. 

 

I know someone has done it! 

 

Can some one point me to a reference for how to route two wan nics and two internal nics on the same box. 

 

I have tried using ip add to setup two separate lookup tables and route tables but to know avail. Any help greatly appreciated!

 

This is what I have

 

66.92.114.46                              66.92.114.46                              209.141.2.194
