-This target allows to alter the MSS value of TCP SYN packets, to control
-the maximum size for that connection (usually limiting it to your
-outgoing interface's MTU minus 60). Of course, it can only be used
-in conjunction with
-.BR "-p tcp" .
-It is only valid in the
-.BR mangle
-This target is used to overcome criminally braindead ISPs or servers
-which block ICMPv6 Packet Too Big packets or are unable to send them.
-The symptoms of this problem are that everything works fine from your
-Linux firewall/router, but machines behind it can never exchange large
-.PD 0
-.RS 0.1i
-.TP 0.3i
-Web browsers connect, then hang with no data received.
-Small mail works fine, but large emails hang.
-ssh works fine, but scp hangs after initial handshaking.
-Workaround: activate this option and add a rule to your firewall
-configuration like:
- ip6tables -t mangle -A FORWARD -p tcp --tcp-flags SYN,RST SYN \\
- -j TCPMSS --clamp-mss-to-pmtu
-.BI "--set-mss " "value"
-Explicitly set MSS option to specified value.
-.B "--clamp-mss-to-pmtu"
-Automatically clamp MSS value to (path_MTU - 60).
-These options are mutually exclusive.
