setfib+pf

[Dimitar Vasilev]

Hi, I originally posted my message to questions, however no response for
about a week. Therefore I'm reposting here. Original question available at
http://lists.freebsd.org/pipermail/freebsd-questions/2009-January/190056.html
For those who prefer reading human text, here are my questions:

I'd like to ask on the best options for using setfib and pf in a non-BGP
environment. I will run 2 uplinks, with VLANs for internal networks and want
to fail over external links if one of them fails.(Extended note as of 13.01:
Uplink routers will be a WRT54GL with OpenWRT and an Alix box hopefully.
Vlan tagging also possible there. Alix will be the controlling router
station for failover).

Currently pf supports to the best of my knowledge:

a) rtable - this means i can create the routing tables with setfib and then
use pass from  .... rtable N( N >1 <16) or give out directly network ranges
b) route-to - pass in/out on X from ... route-to
c) packet tagging - i can tag networks and use standalone or through routing
tags. Anyone aware if is it ok to use /etc/gateways without running routed
or how can i label routes alternatively? If I apply the same for
/etc/networks or both /etc/gateways and networks will it be ok?

pass in from any to $big_salad via $fridge keep state for example?

d) pass in from route N(192.168.1.1 for example) to... - saw this on
http://www.mail-archive.com/pf@benzedrine.cx/msg07220.html and requires BGP
to make tags speak anything but network numbers.
e) use the vlan id's

I'd much appreciate if someone thinks with me for the best options of using
the setfib features along with pf.

Thanks and regards,
