I'm using an older version of ASG Essential Firewall (7.500) as a backup to our regular firewall. I'm doing some testing currently, and I connected to the ASG box and ran iptables --list -n to look at the iptables chains from the shell. I noticed that the very first rule in the INPUT chain is the following.
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
Doesn't this rule's existence mean that anything will be allowed? Looking through my rules in the web interface for ASG Essential, I do not see this rule.
Thanks for any input!
