Hello,
      My server is Mandrake 10.1
eth0 is WAN with static IP connected to 512k DSL
eth1 is LAN

I am trying to write iptables rules and I am 
stuck with some error.

My iptable file is as follows :

# Generated by iptables-save v1.2.9 on Thu Oct 21 05:32:36 2004
*nat
:OUTPUT ACCEPT [0:0]
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
-A POSTROUTING -o eth0 -j MASQUERADE
COMMIT

-A INPUT -j ACCEPT
-A INPUT -s 127.0.0.1 -j ACCEPT
-A INPUT -p tcp -m tcp -i eth1 -o eth0 --dport 3128 --sport 80 -j ACCEPT
-A INPUT -p udp -m udp -i eth1 -o eth0 --dport 3128 --sport 80 -j ACCEPT
COMMIT
# Completed on Thu Oct 21 05:32:36 2004

When I am trying to save I get the following error :

iptables-restore v1.2.9: Can't use -o with INPUT

Error occurred at line: 25
Try `iptables-restore -h' or 'iptables-restore --help' for more information.

Can anybody guide me ?

Thanks in advance
