Hello,
My server is on Mandriva 10.1
eth0 is WAN with static IP connected to 512K DSL
eth1 is LAN - 192.168.0.0/24 and 192.168.21.0/24
My rules are as follows :

Now one problem got solved after chaging
but another has started because of that.
-A INPUT -p tcp -m tcp -i eth1 --dport 3128 --sport 1024:65535 -j ACCEPT
-A INPUT -p udp -m udp -i eth1 --dport 3128 --sport 1024:65535 -j ACCEPT
Originally sport was set to : --sport 80
I changed to : --sport 1024:65535
after corrections from Jason.
Now I think my mail are not going through
which I think is because " 1024 ".
Please correct me if I am wrong.
The squid part makes me happy but not the
mail part.
What corrections need to be made.
Thanks in advance
Varun
