Using iptables 1.4.0rc1(svn7083), iptables seems to have problems
autoloading TCPMSS:
18:53 ichi:/ws/iptables # strace -e open ./iptables -t mangle -A OUTPUT
-d 1.3.3.7 -p tcp --syn -j TCPMSS --clamp-mss-to-pmtu
open("/ws/iptables/extensions/libxt_tcp.so", O_RDONLY) = 3
open("/ws/iptables/extensions/libxt_TCPMSS.so", O_RDONLY) = 3
iptables: No chain/target/match by that name
18:53 ichi:/ws/iptables # modinfo xt_TCPMSS
filename:
/lib/modules/2.6.23.1-900.ccj58-regular/kernel/net/netfilter/xt_TCPMSS.ko
alias: ip6t_TCPMSS
alias: ipt_TCPMSS
description: x_tables TCP MSS modification module
author: Marc Boucher <marc@mbsi.ca>
license: GPL
srcversion: F9280CB30B14724A70F943F
depends: x_tables
vermagic: 2.6.23.1-900.ccj58-regular SMP mod_unload 586
The aliases are there (a common source of errors is lacking these
aliases). If I manually `modprobe xt_TCPMSS`, iptables succeeds. Any
idea?

Works fine for me. Does "modprobe ipt_TCPMSS" work?

No, it does not, that is odd.
13:33 ichi:../misc/suser-jengelh # modprobe ipt_TCPMSS
WARNING: module 'xt_TCPMSS' is unsupported
FATAL: Module ipt_TCPMSS not found.
