It is the ISA if the clients are set to forward HTTP requests to the ISA. But that's just the http part of Messenger. In this case you'd have to hope that the upstream firewall supports the messenger protocols to use the full feature set of messenger. ----- Shawn R.

This probably should be attacked from a different angle (i.e. your upstream firewall causing the issue) Or am I way off the mark? On call this week and not a lot of sleep last night...... I might be in my own little world today..... -----Original Message----- From: Quillman Shawn (RBNA/CSA1) * [mailto:Shawn.Quillman@xxxxxxxxxxxx] Sent: Tuesday, August 31, 2004 11:23 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA 2000 Cache Mode http://www.ISAserver.org You're assuming that there is not an upstream firewall that the ISA is passing traffic to. Messenger does its thing mainly over http so the ISA would need to be configured to allow things through (which may or may not happen depending on what features of Messenger are desired - see Greg's msg below). Unless the ISA is bypassed, obviously, but I would assume that's not the desire here. My guess is that Greg is correct. Ixnay on the ideovay. -Shawn ----- Shawn R.

Sounds like you have another issue.... Think of ISA in this case as a network bridge with a hard drive.... -----Original Message----- From: Ramdhari, Ravesh [mailto:ravesh@xxxxxxxxxxxxxxxxx] Sent: Tuesday, August 31, 2004 8:52 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA 2000 Cache Mode http://www.ISAserver.org Hi Greg, I will test this and let you know. However I don't need voice and video, so here's a plus for now. Thanks -----Original Message----- From: Greg Mulholland [mailto:greg@xxxxxxxxxxxxxx] Sent: Tuesday, August 31, 2004 2:09 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA 2000 Cache Mode http://www.ISAserver.org <rant>Obviously we need to make it easier for people to find the right information, short of running "search the web classes" because this topic comes up as much as anything else and the answer is always the same. </rant> Get Jim's msnim.zip file and run the extracted script on your ISA. This will create the necessary protocols for MSN. However, since you didn't say, I'll assume you want to use voice and video, well here's the thing, you cant. Messenger voice and video uses SIP which ISA as yet, doesn't support. Until then your toast, unless of course the person initiating the call is not behind a NAT service, like ISA or some kind of NAT firewall. If you want voice and video try net meeting, works well with ISA.
