IP Routing Question

[Goran Gajic]

Hi,


You can try using ipf filter to impose source-policy routing:

cat > ipf.example
pass in quick on em1 to em1:192.168.1.2 from 10.1.0.0/16 to  a.b.c.d/32
^d
ipf -f ipf.example

This way you will re-route all packets coming from source 10.1/16 to 
destination a.b.c.d to go to address 192.168.1.2 not to a.b.c.d
Note that you have to rebuild your kernel in order to have options 
IPFILTER enabled.

gg.
