Hello list,
I have a problem with my masquerading.
Can someone supply me a basic configuration. I want to have
the private network
open for everything.
The current rules are below. Works for pop ,http etc. But ftp
is not proper and connecting to an outside
smtp server is a problem too. I can send very small emails but
if some larger email or attachment it stops after transferring some kbs.
What am I missing here ? The server is redhat 9 pppoe to the dsl
modem.
#!/bin/sh
modprobe ip_conntrack_ftp
modprobe iptable_nat iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT echo 1 >/proc/sys/net/ipv4/ip_forward echo 1 >/proc/sys/net/ipv4/ip_dynaddr iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu Thank you in advance,
Peter
