-----BEGIN PGP SIGNED MESSAGE-----

The subject is the problem.
I am using OS/2 connect with a TIA connection with IP forwarding turned on.

Access at the linux side is fine, but I get a these messages in the log. Lots of them!

The message starts with> kernel: icmp : ICMP redirect from (OS/2 IP_addr) on eth0 (linux box) ignored.

I know I missed something in the setup somewhere. Anyone Know?  Is icmpred suppose to
be on or off? Where? The messages only start when the os2 box makes the internet connection.
Then they continue even if I disconnect. I've been pretty clueless on this one.

I'm running linux 1.3.32 and its great!

The os/2 side had -icmpred option on ifconfig. I took it out didn't change anything.

        All hints will be accepted.

TIA ..............

This is caused by using static routes instead of dynamic routing.
Try to avoid static routes wherever possible, in most cases you don't
need any at all. Run a routing daemon like "routed" or "gated". routed
is very easy to set up (on host which don't need to supply routing info
start it in quiet mode with the option "-q")

1. These "ICMP redirect from xxx.xxx.xxx.xxx" errors

I've seen a few people ask - but haven't seen a response.

Can anyone tell us what these are caused by? I though they looked like
source-routed packets, but our local cisco disables source-routes and our
Linux boxes are compiled to ignore source-routes - so I can't figure out
what they are caused by.

We get tonnes of them on a mail server here - the addresses are all mail
servers - a lot of them from rather large outfits...
