pf load balancing, macros, tables...

Hi all, I'm in the process of setting up a group of load balanced servers, and I've come across something (I think) is a bit unusal with macros and tables and load balancing. I use tables fairly extensively in our two 3.6-stable OBSD pf/CARP firewalls, and I'd like to use them in configuring our

Maybe I'm missing something about your requirements, but why not just us MRTG? It will measure input/output on as many interfaces as you want. Since all it *really* does is graph data, it can also be used to measure virtually anything. It is relatively easy to create scripts that gather data

What exactly does PF think 'lowdelay' is though? I need to specificly make sure IP precedence 5 packets are given priority over other traffic (except maybe IP precedence 6 and 7). I found buried in the pf.conf man page that I should be able to specify a TOS value using something like: pass

It's probably some simple mistake in manipulating the ruleset. Make sure you have both filter and translation rules loaded successfully, i.e. run # pfctl -sn No errors... and check whether rdr rule is correctly loaded like you intend. Check. One somewhat obscure mistake is to run pfctl -R -f
