The problem is that just because the Diameter node has bound to an address, does not imply that it's possible for a specific peer to try and connect to. E.g., node A, node B are both behind different firewalls, node A binds to 192.168.1.1, on node B's network, 192.168.1.1 is assigned to a completely different machine. Do you have a specific suggestion for the algorithm a node should use in selecting which of the nodes addresses are put in the Host-IP-Address field? > > > Best just to treat the field as informational. > > Don't fully agree. In case of TCP I could. In case of SCTP I don't. For SCTP Host-IP-Address is utterly redundant. SCTP already supports multi-homing and telling peers of additional addresses (although in practice, I've seen that go hilariously wrong).
