Re: Anyone familiar with the IP packet filtering rules on IBM i ?

Boy, that is pretty sparse, Richard!

I worked with PF extensively on OpenBSD but the syntax here looks different.

I'd try 1.1.* just as a SWAG.

Using LODIPFTR I have the IP address packet rules working just fine and
can filter a full ip address like this:

Ex: SRCADDR = 1.1.1.1 or DSTADDR = 1.1.1.1

Is there a way to use some wildcarding to just filter mask on the first
part of the IP address. In this example just the first two digits. This way
I can filter to a particular network rather than down to the specific IP if
the IP address changes:

Desired Filter Ex: SRCADDR = 1.1.0.0 or DSTADDR = 1.1.0.0

I tried this: 1.1.0.0/16 and it doesn't work. Also tried just: 1.1.0.0
and that doesn't work either. Only thing that seems to work is a specific
IP address.
