So this is multicast reply, telling modem to connect?
Why not TCP connect from router to modem? Makes more sense to me, the modem is the peer offering a service.
Maybe add a TcpPort TLV in the Peer Discovery, this allows other than IANA assigned ports.

Please don't.

Yes, here the full set TLV exchange takes place. This should not be in the Peer Discovery. That's why I suggested to put this in the Peer Offer.

I'm fine with three way handshake, not with this two way. Or use TCP disconnect when modem modem is not willing to accept first message from router.
