When DLSW+ peers begin communication, they open a connection for each
direction. After exchange they decide to drop one of the TCP connections.
PeerA contacts PeerB on TCP 2065 and then Peer B returns contact by
initiating another TCP session on TCP 2066. I can't remember the ports but
you get the concept. Initially there are two TCP sessions open between
peers.
The peers then decide to drop one of the two connections and use the single
bi-directional connection based on who has the higher IP address. This is
why DLSW+ behind NAT can be a problem.
I think the statement is saying the return connection from the far end peer
will use the same encapsulation as it was contacted with for the second,
return, connection.
I'm starting to confuse myself.

I am reading basics of dlsw. And I read(CAN SOME EXPLAIN IT TO ME ) :
If FST or direct encapsulation is configured, the initial peer connection
request will use either FST or direct encapsulation. The receiving(passive)
peer will assume the encapsulation method implied by the initial peer
connection request.
