Avoiding Fragmentation
-
-Fragmentation of encapsulated return packets to the LAC may be avoided
-for TCP sessions by adding a firewall rule to clamps the MSS on
-outgoing SYN packets.
-
-The following is appropriate for interfaces with a typical MTU of
-1500:
-
-
-iptables -A FORWARD -i tun+ -o eth0 \
- -p tcp --tcp-flags SYN,RST SYN \
- -m tcpmss --mss 1413:1600 \
- -j TCPMSS --set-mss 1412

Performance is great.
