[Sshguard-users] blocking ports different from 22

[michele <mi...@ma...>]

On a FreeBSD machine, I've an ssh daemon listening on a port different
from the default 22.
After some failures, the following IPFILTER rule is added to my
ipf.rules:

block in quick proto tcp from x.x.x.x to any port = 22

How can I tell to sshguard (1.3) to block my ssh port and not the
default 22?

Thanks
