My mistake. As Pascal stated, you have to specify a "-p tcp --tcp-flags SYN,RST SYN" as well, as TCPMSS clamping only works on TCP packets with SYN flag set: iptables -t mangle -A FORWARD -o ppp0 -p tcp \ --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu It should work better. -- http://sid.rstack.org/ PGP KeyID: 157E98EE FingerPrint: FA62226DA9E72FA8AECAA240008B480E157E98EE >> Hi!
