Thanks both – so if I do
sudo ufw allow from 192.168.0.99 to any port 22
then am I doing anything other than saying 192.168.0.99 can ssh in to this machine? This is what I’m trying to achieve but the “any” is confusing me somewhat – though the rule itself does seem to be doing what I want.
Cheers
Rob

man ufw doesn't seem to have much to say on the matter, but
https://help.ubuntu.com/community/UFW
suggests "any" in this context means any destination IP address (given that there may be many associated with a host):
Allow by specific port, IP address and protocol
sudo ufw allow from <target> to <destination> port <port number> proto <protocol name>
example: allow IP address 192.168.0.4 access to port 22 using TCP
sudo ufw allow from 192.168.0.4 to any port 22 proto tcp

From any port on y Maybe?

Hi all
Simple question (I hope). If I’m opening port x from ip address y on my network with the following command
sudo ufw allow from y to any port x
…then where does the “any” come from? Anyone know? Seems strange to say “any port” then list the port number – unless I’ve misunderstood the rule.
Cheers
