Ok, done that. I'm still getting this 500 target principle name is incorrect. Server can ping the site name and get the internal IP. Listener is listening on right IP Certificate name and host header name match. Same certificate is in ISA and IIS. The first packet fails on the publishing rule. It is going to the internal IP:443 Second packet is initialization on the public IP Third packet is close on the public IP. Where I am going wrong? thanks, Amy Babinchak Harbor Computer Services |(248) 850-8616 Tech Blog http://securesmb.harborcomputerservices.net Client Blog http://smalltechnotes.blogspot.com Website http://www.harborcomputerservices.net -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Moffat Sent: Wednesday, April 02, 2008 3:42 PM To: ISAPros Mailing List Subject: [isapros] Re: 2 IP's on External NIC You haven't defined it in ISA Network have you? All you need to do is add it to the nics IP properties and that's it. Select the ip from the listener tab.

I created SecondIP because I need to use a second listener too. Listener 1 is on port 443 on the first IP and listener 2 is on the port 443 on the second IP. thanks, Amy Babinchak Harbor Computer Services |(248) 850-8616 Tech Blog http://securesmb.harborcomputerservices.net Client Blog http://smalltechnotes.blogspot.com Website http://www.harborcomputerservices.net -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Moffat Sent: Tuesday, April 01, 2008 8:21 PM To: ISAPros Mailing List Subject: [isapros] Re: 2 IP's on External NIC That's the way to do it.

I need to publish 2 SSL websites with different listeners. 1 to each IP. I added the second IP to the external and setup the rule and it worked perfectly for 3 days and then the server was rebooted for patches. Now I have the Firewall service complaining about the second IP on the external NIC and the rule no longer works. thanks, Amy Babinchak Harbor Computer Services |(248) 850-8616 Tech Blog http://securesmb.harborcomputerservices.net Client Blog http://smalltechnotes.blogspot.com Website http://www.harborcomputerservices.net
