I am trying to configure an SRX550 to function as a layer 2 firewall. I am doing it via J-Web as I haven't had success via the CLI either, so I was hoping J-Web would overcome whatever silliness I am missing in the CLI.
I go to Ports > Interfaces and then choose 'Switch to L2 Mode' and am prompted to enter a management IP with subnet mask. What is the format for this field? No matter what I enter or how I enter it I am told it's an invalid management address. For example I enter 192.168.1.1/24 and I receive an error stating that it's an invalid management address. If I enter just 192.168.1.1 I receive an error telling me to put in a subnet mask. I've tried using subnet masks and CIDR notation separated by several common separation markers (space, comma, colon, etc.), but get no joy.
I am relatively new to JunOS and certainly J-Web, so if this goes in the stupid question column I apologize, but Google didn't yield any helpful results.
