The syntax *is* the same, in this case.  The only ipf syntax
feature that ipf users are likely to miss from pf syntax is the
use of rule `groups', but this is not used here.

Sorry, I see the syntax is the same.

Unless the syntax is the same, that looks more like pf than ipf.

Subject: Simple firewall question: Blocking a handful of IPs


I'm not extremely comfortable with doing firewall testing remotely
on
production systems, but I need to set up some incoming IP blocks.
I've got a FreeBSD RELENG_5_4 system with public interface rl0.

I want all traffic allowed unfettered, except traffic from
particular
IPs to be completely blocked coming in.

Can someone show me which ipf rules to use to get that result?

Thanks,
Wade
