When TCP traffic, such as the three-way handshake, passes across the tunnel, the router will see the MSS is set to 1460 in the TCP header. Knowing that the MSS of the tunnel is lower than this, it will rewrite this to 1436. Now, the host at the other end will see the MSS for the path, and adjust the maximum payload for this connection accordingly.
