No. If mhomed is off (default), ser will send a message on the same
socket it received it (so if you receive the message on .81, it will get
sent on .81 too).

If mhomed is on ser will try to guess the outgoing interface and it will
use it to send the message: if the outgoing interface for the message
would be .81, then ser will send on .81, if it would be .82 => the
message will be sent on .82. Notice that turning mhomed will introduce a
performance penalty.

The order of the listen statement is important for forwarding from tcp
to udp, ipv6 to ipv4, locally generated requests (e.g. as a result of a
fifo command). In all this cases the first non-loopback interface will
be used.
