Hi William. Thanks a lot for your help.

Im having some trouble recompiling my kernel after a = installed the
patch.

Im running RH 7.3 with kernel 2.4.18-3.

The patch I installed is routes-2.4.16-6.diff. I got = no errors
installing it.

I added the multipath support, and recompiled = it.

The make dep and the make bzImage went fine.

I got error during the make modules.

These are the errors:

Output.c: in function 'cipe_xmit'
Output.c:175 too few arguments to function = 'ip_route_output'
Make[3]: *** [output.o] error 1
Make[3]: leaving directory = '/usr/src/linux-2.4.18-3/drivers/addon/cipe'
Make[2]: *** [_modsubdir_cipe] error 2
Make[2]: leaving directory = '/usr/src/linux-2.4.18-3/drivers/addon'
Make[1]: *** [_modsubdir_addon] error 2
Make[1]: leaving directory = '/usr/src/linux-2.4.18-3/drivers
Make: *** [_mod_drivers] error 2

After I got that error, a formatted and reinstalled = redhat 7.3. Then I
used the newer patch (routes-2.4.19-8.diff), and I = got error installing,
and of course I couldn't recompile it.

I formatted again to see if I were doing something = wrong recompiling.
But this time I didn't patch and recompile it. I got = no errors...

Any ideas? Am I using the wrong patch?

Thanks a lot,

Ron

You will need to recompile your kernel with multpath = support. Also
before you compile apply Julian's patches to the = kernel.

http://www.linuxvirtualserver.org/~julian/#routes<= /FONT>

Once that is done check out the Nano-HOWTO

That should get you on your way. The linux router = will also have to
perform NAT, more than likely DNAT, for things to = work properly.
