I have a Juniper Netscreen 5GT - Firmware Version 5.0.0r8.1 (Firewall + VPN)
Using the GUI I have no option to enable "Incoming NAT" under Network -> Interfaces -> Trust interface -> Edit -> DIP (which is what I think is the option I need to enable to solve my original issue). Now I have 2 other Juniper Netscreen 5GT's with firmware version 5.3.0r6.0 and they DO have the option to enable "Incoming NAT". My first thought was that I need to upgrade the firmware on the 1 oddball firewall to match the other 2 newer firewalls, but thinking more about it I was wondering if there was a command that I can use within the CLI to enable this "Incoming NAT" option for the DIP. This way I can avoid spending extra money buying a service contract to get the firmware upgrade and avoid running into the possibility of messing up the current configuration when applying the upgraded firmware.
Any help would be appreciated. Thank You!
