Using FreeBSD as a BGP router has network issues caused by suboptimal
default IPv4 source address selection when connected to Internet
Exchanges (which are required to use IPs that aren't routable on the
Internet). I was hoping to find more elegant workarounds or encourage
FreeBSD to add source IPv4 selection akin to the existing IPv6 source
address selection (no_prefer_iface and prefer_source).
I assume that there is a group of BGP enthusiasts using FreeBSD lurking
on freebsd-net. What have you done to solve this problem?

<p>For DNS in such situations I start unbound locally and bind it to
an internal interface or an IP on lo0 and then tell unbound to
just use that IP only (outgoing-interface IIRC) that is
advertised out as a work around. Its not a proper solution, but
will get your resolver working at least. I run into this problem
in layered networks where the next hop is often RFC 1918 addrs. I
bind applications to internal NICs that have addresses that have
routing to/from.<br>
