A follow-up to this request: It is much easier to accomplish when settings routes with a source address that is a public IP like this: ip route add default via 10.10.10.1 src 192.0.2.24 ICMP errors will then use 192.0.2.24 as the source address. No need for a kernel patch. Thanks for all the input.
