Re: Masquerading problems (fix)

[=?unknown-8bit?q?J=F6rgen?= Danielsson <jorgen_d@yahoo.com>]

This is how i have it

### Allow masquerading for internal boxes ###
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

### Make sure mtu is never changed 
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j
TCPMSS --clamp-mss-to-pmtu


Had the same problem as you earlier, that fixed the
prob.
