I have a firewall in transparent mode.
Its performing no NAT no routing.
we are only using it as IDS/IPS
Port 20-> Port 22 any any IDS Rules set to monitor
Port 22-> Port 20 any any IDS Rules set to monitor
Do I need to have any of the session helpers enabled.
I believe the SIP Helper was causing issues with our phones.
I don’t want any of the FTP or TFTP or DNS to have issues either.
Go to Solution.
Session helpers are required to open dynamic port(dynmaic policy) and create nat pinhole.
Now in transparent mode you don't have any nat, nor opening port is required as you have policy allowing traffic in both directions.
You can safely disable all the session helpers.
