Routing using a virtual with SNAT none may select a source port of zero

MRF allows routing to a peer without a transport-config selected. If a peer does not have a transport-config, the transport of the message originating connection will be used to create the outgoing connection. If originating connection used a virtual server as its transport, the serverside of the virtual server will be used to create the outgoing connection.
If the virtual server had a SNAT setting of none and the 'source-port' attribute set to 'preserve' or 'preserve-strict', the outgoing connection will be created with a source port of zero instead of the remote port of the originating connection.
