My isp gives me a bunch of dynamic external ip addresses via dhcp one per nic. They don't share common default gateway route all together, so I'm forced to put each next in its own rdomain.
As so, http://www.openbsd.org/faq/pf/pools.html#nat or http://www.openbsd.org/faq/pf/pools.html#outgoing examples are not applicable. I'm just interested in random redistribution. Here's an ugly solution I currently use: match out on em0 inet from lan:network nat-to (em0:0) match out on em1 inet from lan:network nat-to (em1:0) match out on em2 inet from lan:network nat-to (em2:0) pass in on lan inet from lan:network to !lan:0 # fallback pass in on lan inet from lan:network to !lan:0 rtable 1 probability 34% pass in on lan inet from lan:network to !lan:0 rtable 2 probability 34% What would be the correct way of doing this? Is it possible to achieve this using vether(4) without big performance penalty (which occurs when real nic and virtual interface which relies on it are not in the same rdomain)? Thanks!
