Subject: RE: IBM IP Addresses / Ports
I show these two addresses for ECS:
129.42.160.16
207.25.252.196
I set them up years ago at the direction of IBM support due to ECS issues
when I configured our load-balance/fail-over NIC setup.

Subject: IBM IP Addresses / Ports
A couple of my customers have put requirements it to lock down
inbound/outbound communications in their firewalls to only known addresses.
I've been asked for a list of IBM IPs and ports that need to be open. I've
compiled the following list. Does anyone know of any others that I need to
add? I can't find any specific information on ESS but I suspect that's
because IBM only uses Download Director for that function. Here's the list
so far: ( I tried to format it so all the mail clients won't mess it up )
