Quand il y a un PB, il y a *peut être* une solution :
man iptables :
TCPMSS
This target allows to alter the MSS value of TCP SYN packets, to con-
trol the maximum size for that connection (usually limiting it to your
outgoing interface's MTU minus 40). Of course, it can only be used in
conjunction with -p tcp.
_This target 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 con-
figuration like:
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
-j TCPMSS --clamp-mss-to-pmtu
Hé Hé !
