Consider a TCP connection that is long-lived enough (> 24 days, with
timestamp clock frequency of 1ms) for timestamp wraparound to occur at
one end. Assume that the connection has *not* been idle for more than 24
days. According to RFC1323, the PAWS check would drop all incoming
segments from the host that wrapped, since TSVal would be less than
TSRecent and TSRecent will not get updated.

Am I missing something here?

thanks
