Re: load balance (rdr) with tables

[Gustavo A. Baratto]

I posted the wrong rule in my last mesg:
the rdr rule that DOES NOT work is this:
---
table <smtp> persist {10.10.10.10, 10.10.10.11}
rdr pass on $ext_if proto tcp from any to any port {25 110 143} ->
<smtp> round-robin sticky-address
---
This works fine:
---
$mail_pool = {10.10.10.10, 10.10.10.11}
rdr pass on $ext_if proto tcp from any to any port {25 110 143} ->
$mail_pool round-robin sticky-address

Subject: load balance (rdr) with tables


Greetings all,
I'm quite new in pf, and I'm having some problem with a load balance rule 
to a pool defined in a table. This is roughly what I have:
------
table <smtp> persist {10.10.10.10, 10.10.10.11}
rdr pass on $ext_if proto tcp from any to any port {25 110 143} -> 
$mail_pool round-robin sticky-address
------

# pfctl -s nat
rdr pass on xl0 proto tcp from any to any port = smtp -> <smtp> 
round-robin sticky-address
rdr pass on xl0 proto tcp from any to any port = http -> <smtp> 
round-robin sticky-address
rdr pass on xl0 proto tcp from any to any port = pop3 -> <smtp> 
round-robin sticky-address
rdr pass on xl0 proto tcp from any to any port = imap -> <smtp> 
round-robin sticky-address
rdr pass on xl0 proto tcp from any to any port = https -> <smtp> 
round-robin sticky-address

The strange thing is that exactly the same rdr rule works fine with I use 
a macro instead of a table, eventhough the pf FAQ says:
-------
round-robin - loops through the address pool in sequence. This is the 
default method and also the only method allowed when the address pool is 
specified using a table.
-------

Using freebsd port of pf, which is the equivalent to version in openbsd 
3.5

thanks for any suggestion ;)
