Why not have asymmetrical connection definitions? Use "left=%defaultroute" on
the sux.suxer.net machine, and "right=%defaultroute" on tux...

... but I see that you've got both nexthops on the same network. In that case,
if relevant, you could use left/rightnexthop=%direct, to use the peer's IP
address directly. Then again, I'm pretty certain you could use the opposite
FQDN in place of your nexthop values as well.
