hmm… still not getting what I needed… I want to setup and only allow any machine within the same subnet to access but it’s wired that I can only add 1 hard IP address… or I missed anything?
If you want a single subnet, the format is ip-address-of-net/maskbits, so for a typical home-router subnet with 255 addresses, an example would be 192.168.1.0/24. 24 mask bits is equivalent to a subnet mask of 255.255.255.0 if that’s more familiar? Your original question with xxx.xxx.xxx.* would be correctly specified as xxx.xxx.xxx.0/24
Thanks for your reply, though I tried the same format and returned “Enter a valid IPv4 address.” and cannot be saved… Somehow I couldn’t find any documents for this functions and no clue how to setup correctly …
No luck… whenever I add “/” it prompts “Enter a valid IPv4 address.” and the save button will be dimmed. And my last try that can save is without the “/xx”. But then it seems not recognized as a subnet but as an individual IP address and no PC can connect to it.
