specify multiple addresses / only listen on private addresses

[muja]

currently dora listens on all addresses unless a single v4/v6 address is specified. My setup includes multiple private interfaces and there is currently no way to specify all private IPs or excluding the public IP.

Thanks! That should be a pretty small change

Looking at this again. dora is usually run on inaddr_any, then we use the interfaces in the config if necessary to filter out messages using info from recvmsg

I wonder if we couldn't allow the config to accept something like

interfaces:
   - [email protected]

then bind to inaddr_any, and then only process messages with the interface & ip specified there. would that work for you do you think?
