Hi All,
I am using Iptables with Ip Masquearde, with a simple rc.firewall script to share my internet connection for the last so many months, today I configured a new server with the same settings but after the script executes I am not able to ping computers in my local network and the moment I restart the Iptables I am able too?I just dont understand where I am going wrong?Any pointers will be apprecaited.
I have enabled Ipforward!
Regards
Harish

It sounds like your netfilter rules are not being loaded on startup.
Check your startup scripts (what, and where, they might be, depends entirely
on your Linux distribution) to make sure that your ruleset is being loaded
when the new system boots up.

Antony.

The other thing to check is the ipv4_forward value.
In some linux distros, the ipforward option needs to be set up in the
/etc/sysconfig/network script, and isn't set automatically with iptables
restore.

We don't know what your script looks like so it's going to be hard.
If you can not ping from the firewall to the PC's then you should be
allowing INPUT traffic from your lan and OUTPUT traffic from the firewall.
Reading the above it seems to me that forwarding doesn't have anything to do
with this.
Not much more one can say without the rules.
Gr,
Rob

Maybe you could actually show us the rules.
