Hi, I read the howto of iproute, I have the same case with HOWTO, the difference is that the whole incoming traffic goes through interface 0, the other difference is that I do not want to balance the out going traffic, because I have specific networks to take it throughout another interface. Mi Case IF1 --> Input and Output IF2 --> Only aoutput for three Network I need Help, How can I execute my case with the case of HowTo? Thanks In Advanced, Regards, 4.2.
