Routing table tweaking

[James Stark]

Running default 2.6 install on a 486 with 8Mb of RAM
(thx Theo & Cyber...yes it was the memory) -

tl0 and ne3 are my NICs, and I currently have a default route as

Destination Gateway Flags Refs Use Mtu Interface
default 10.10.10.254 UGS 0 0 - tl0

yet I would like this route to be linked to my ne3 interface, not tl0.
I found the appropriate code in /etc/netstart that adds this default
route, and it looked like it used the route command.

So based upon Route(8):
the -ifp or -ifa modifiers may be used to de-
termine the interface or interface address.

I should be able to do change the command in /etc/netstart/ from
route -n add -host default 'cat /etc/mygate'
to
route -n add -host default 'cat /etc/mygate' -ipf ne3

I tried testing this manually, and I couldn't get route to acccpt the
-ipf ne3 command. Any ideas here? I think I am on the right track, but
if this is the completely convoluted way to change the interface the default
route uses, the please let me know

Thanks in advance
James

The kernel will select the correct interface based on your ip addresses
and netmasks.

The output you have described indicates that the kernel feels that the
best (only?) route to 10.10.10.254 is via tl0.

You probably want to check your configuration on tl0 and ne3:
ifconfig tl0
ifconfig ne3
will show you which card is configured to which subnet.

My best guess is that you've got the bindings roundabout.

Sorry for the typo below - using the flag -ifp (not IPF)
