how to add rule by UFW that will allow connect to let's say SSH from ip range 10.0.0.10-10.0.0.20 ?
does UFW supports --src-range function like iptables?

Referring to this question:
https://askubuntu.com/questions/646424/ufw-allow-range-of-ip-addresees
One way to do it is to split it into several rules (not exhaustively listing out all IP addresses though):
Considering that 10.0.0.10-20: (I only list out
- 10 -> 0000 1010
- 11 -> 0000 1011
- 12 -> 0000 1100
...
- 15 -> 0000 1111
- 16 -> 0001 0000
...
- 19 -> 0001 0011
- 20 -> 0001 0100
You would need 4 rules:
ufw allow from 10.0.0.10/31
ufw allow from 10.0.0.12/30
ufw allow from 10.0.0.16/30
ufw allow from 10.0.0.20

this is no good becouse i need to allow 120 ip to access a mysql database..... i think I'll stick strictly to iptables; beside i was thinking that ufw is capable of this. thanks. – integratorIT Dec 10 '19 at 13:05
