Hi Shane,

In Pix FW, if you have 2 interfaces with same security levels, they won't communicate with each other. You need to define a different security level for the two interfaces. Thanks!

Best Regards,

Interfaces with equal security levels do not allow traffic between them. Yes, you will have to reduce the security level of one of the interfaces and add ACL to allow the communications between them.


I found this command on the internet while waiting for a reply on my post and entered it but i still do not get any traffic to Company A's interface or to my outside interface (security level 0)

Also as a side note i have ran the packet tracer on company b's interface and i have an acl that is stopping traffic, i have an implicit rule source and destination both are set to any, and the action is set to deny.
