+         This option adds a `TCPMSS' target, which allows you 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 40).
+
+         This is used to overcome criminally braindead ISPs or servers which
+         block ICMP Fragmentation Needed packets.  The symptoms of this
+         problem are that everything works fine from your Linux
+         firewall/router, but machines behind it can never exchange large
+         packets:
+               1) Web browsers connect, then hang with no data received.
+               2) Small mail works fine, but large emails hang.
+               3) ssh works fine, but scp hangs after initial handshaking.
+
+         Workaround: activate this option and add a rule to your firewall
+         configuration like:
+
+         iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
+                        -j TCPMSS --clamp-mss-to-pmtu
