Our network, security, firewall, guy feels that if the vulnerability is there, firewall will not make a difference.
Networking/firewall is not my area, so I really need to gather additional info to confirm.

Not specifically aware of this BUT it would require that you allow direct access to your server from outside your protected network to be vulnerable. Not many of my customers (I can think of exactly 1) have their IBM i servers directly connected to the Internet without a firewall of some sort.

The OSPF implementation in IBM i 6.1 and 7.1, and in z/OS on zSeries servers, does not properly validate Link State Advertisement (LSA) type 1 packets before performing operations on the LSA database, which allows remote attackers to cause a denial of service (routing disruption) or obtain sensitive packet information via a crafted LSA packet, a related issue to CVE-2013-0149.
