Exchange admin, config, connections, pick IMS, go to connections, accept connections, specify by host. Put your gateway in as accept and 0.0.0.0 in as reject (second entry:-) Should do it Harriet -----Original Message----- From: Weathersby, Bryce [mailto:[EMAIL PROTECTED] Sent: 23 November 2004 15:20 To: Exchange Discussions Subject: RE: Simple question about IMS That is because I have to with how the network is setup and I cannot change that. The University that we get our network services from allows all machines to have a real IP.. Nothing I can do about that... As we are getting ready to move over to our own network we will have the box inside our firewall and this will not be an issue, but until that happens.. I have to find a way to block Exchange from accepting traffic from anything but my gateway box... -----Original Message----- From: Randal, Phil [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 23, 2004 9:13 AM To: Exchange Discussions Subject: RE: Simple question about IMS Simple answer...
