[tor-relays] Outbound Address differing from exit address

Greetings all, I'm in the process of setting up a few Exits on a Cloud provider here in Iceland (one that I used to work at actually). Since they use Cloudstack it means each address per account gets multiple inbound address per instance and share the same address for outbound traffic. I'm worried that abuse notices will be coming in for this outbound address even though I've got 80 on the exit node's IP showing the standard Tor Exit disclaimer. I've tried to set OutboundBindAddress to the outbound IP using arm but this just causes arm to complain about: "[WARN] Error binding network socket: Cannot assign requested address" Any advice would be appreciated. -J
