[SOLVED] OpenBSD pf round-robin weight

kzl · 07-26-2017, 03:43 AM

Hi!

Using this guide I've successfully done configuring pf load balancing multiwan.
( https://www.openbsd.org/faq/pf/pools.html )
However, my two connections should be weighted 1:15.
In the pf.conf manual ( http://man.openbsd.org/pf.conf ) I've read (for me) some obscure
reference to it at the round-robin section, but no example.

Can you provide me some instructions or reference how to do it?

Thanks in advance

There is an example of round-robin weights in pf.conf(5):

Code:

     In this example, a NAT gateway is set up to translate internal addresses
     using a pool of public addresses (192.0.2.16/28).  A given source address
     is always translated to the same pool address by using the source-hash
     keyword.  The gateway also translates incoming web server connections to
     a group of web servers on the internal network.

         match out on $ext_if inet from any to any nat-to 192.0.2.16/28 \
             source-hash
         match in  on $ext_if proto tcp from any to any port 80 \
             rdr-to { 10.1.2.155 weight 2, 10.1.2.160 weight 1, \
                      10.1.2.161 weight 8 } round-robin

The GRAMMAR section shows weight defined as a component of a host.

Indeed, thank you! I should read more carefully...
Now the config looks like this and I'm getting the full speed of my connections:

Code:

pass in on $lan_if from $lan_net \
route-to { ($wan_if $wan_gw) weight 1, ($wan2_if $wan2_gw) weight 15 } \
round-robin
