NO-NAT-CONTROL

Hi,

I have pix firewall 535 with IOS 7.x version. I have enable it with no-nat-control, to my understanding with this no-nat-control traffic from higher secuirty level to lower secuirty level allowed if there is no access-list. But from low to high still need of static and access-list. But in my case traffic from low to high is permitted without static. My outside network users are able to reach inside network without static.

Please tell me why it is so, why low to high permitted without static or is it the normal behaviour.

Re: NO-NAT-CONTROL

You dont need static you need only ACL in order to passing traffic from lower to higher sec level
