icmp redirect

[Jan Humme <jan.humme@xs4all.nl>]

I am developing an application that will eventually run on a PC with two 
ethernet cards; unfortunately the development PC that I use has only one 
ethernet card (eth0) and no available slots (except for one that I need for 
another purpose).

Doesn't matter, during the development I can have both applications use eth0 
instead, if I can only stop the icmp redirect messages that the kernel sends 
back to the source, whenever it finds out that it is forwarding a packet via 
the same eth0 interface on which it came in.

Of course, I can choke the icmp redirect message using iptables, but is there 
a better (proper) way, to prevent the message from being generated?
