Cisco ASA – Allow traffic between two same security level interfaces

This is just a quick one,

A customer of mine has two companies running in the same building, using the same ISP connection, as such the Firewall is essentially the core of the network. I put in this network and although its not exactly best practise, its a case of making do with what they had and could afford.

The fix for this was inputting the command; Continue reading Cisco ASA – Allow traffic between two same security level interfaces
