Re: Outbound port blocking

[Jim Oberholtzer <midrangel@xxxxxxxxxx>]

You can use the packet filter on the IBM i instance to stop outbound 
packets based on specific port numbers and/or IP addresses  Just the 
same as a firewall can block outbound transactions.

The only reason the packet filter is not called a firewall is there are 
some limitations on the statefulness of the packet filters.  IBM chose 
not to put any further effort into it realizing that most folks would 
use an external firewall.

If you don't like the packet filter idea, a small Cisco 5505 is about 
$500 and could easily solve the problem as well.

Packet filter :  Already paid for.
