Firewall (IPFW) FreeBSD

[protocoles]

Hello Everyone,

Is it possible to block a port using ipfw in freebsd lets say I have a server with multiple IP's and I want to block one of my customer IP's port 25.

Any help would be appreciated,

ipfw add XXX deny ip from any to me ZZ

Change XXX to an ipfw rule number.
Change ZZ to the port number.

That rule would block access to every IP on the server, but you said you want to block only one IP at port 25. So...


ipfw -q add <RULE#> deny all from any to <IP> 25
