i have a problem with iptables in sisela-0.3 - i cannot set the option
we are using sisela in routers in a small wireless-dsl-sharing setup, and
currently have a problem with network-congestion that may be related to
wrong settings of MTU. this page (http://www.hgfelger.de/mss/mss.html)
suggested iptables to correct it, but when i try to execute:
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
iptables v1.2.8: Unknown arg `--clamp-mss-to-pmtu'
is there an easy way to fix this or do i have to re-compile a kernel and
build sisela by hand?
