WAN interface /28 ip range
I have a single /32 static ip address currently assigned to the WAN interface. I need to change this to a /28 as I need to expose devices the internet. On the WAN interface settings it will not take the ip values x.x.x.x/28. Is this possible on a TZ500? Am I missing something or doing something wrong?
Welcome to SonicWall community.
Yes, it should certainly allow you to assign a /28 subnet mask on the WAN interface.
I hope you are entering one of the IP addresses from the pool on the interface with subnet mask as 255.255.255.240.
Also, when you say that it is not allowing it, what error message are you seeing on the bottom right hand side of the screen during the change?

In this case, you should use one of the usable IP address in the range and you can't use both network IP or broadcast IP in any interface.
Example : 184.108.40.206/28
Network ID: 11111111 11111111 11111111 11110000
Total 32 bit - 28 = 4
Last Incremental is 16
Usable IP: 16-2 = 14 usable IP in range
Network IP : 220.127.116.11
First usable IP: 18.104.22.168
Last usable IP: 22.214.171.124
Broadcast IP: 126.96.36.199
You can use from 188.8.131.52 - 184.108.40.206 but make sure use gateway in the range.
No problem at all. Glad that it is all working fine now. Have a good day!
