Hello Miguel,
Alas, I have no idea on directly solving your problem, and
hope that the list's experienced veterans can help you better.
But I have an idea to this: "But I just want to do some local
L4 load balancing. Any idea on how that can be done? ".
Sorry if my suggestion is too far-fetched - but in case
it doesn't work out with IPF, did you consider daemon-based
load-balancing?
I'm sure it is not too difficult (although inefficient for
heavy/frequent loads) to make an inetd service which would
spawn tunnels (netcat's?) to one or another destination. This
can be dome perhaps via some one-liner script (load-balancing
to two targets i.e. by oddity of the current second of time).
Some more efficient approach would be to find a tunneling
software which spawns LWP threads within one OS process.
If this is some specific protocol (like SMTP, LDAP, HTTP)
there are many load-balancing proxies, good and bad. Protocol-
specific proxies are also beneficial in that they can usually
detect dead back-end servers and transparently direct the
clients to live servers.
If anything else, some such proxies are available in source
(scripted or C/C++) and can become a basis for your protocol's
new load-balancer ;)
Hope this helps,
Jim

Hi guys
I would like to create a local L4 load balancing so that the following
is true (the host has IP address 10.226.32.111):
TCP connection to 127.0.0.1/port 1500 on the host gets redirected to
10.226.33.150/1500 the first time.
What OS? As far as I know, you can't do anything on the loopback interface in
Solaris since it's not a real interface.
