Hi,
I wonder why I canīt put an IP Range in the Firewall Rules without it saying that the IP I put there is not right. I mean, there is this extra field behind the / so I suppose its ment to use it like this for example:
11.11.11.0/255
Right ? I need to ban a few IP ranges from my Server. Any Idea how to succeed in this ? Please, i am far away from beeing an expert in these things. Please, if you do know how it works, try to explain it simple if possible.
Thx.

You want to use the bitmask at the end, heres a quick cheat sheet:
11.11.11.11/32 <- just the host 11.11.11.11
11.11.11.0/24 <- the whole 11.11.11.0 network (254 ips)
11.11.0.0/16 <- the 11.11.0.0 network (64k ips)
11.0.0.0/8 <- the 11.0.0.0 network (16million ips)
