SSL problem with Cingular using Exchange ActiveSync
Posted on 2007-03-19
We have Cingular wireless devises that connect through our Custom APN. In this setup, we have phones and Sierra wireless modems that connect to Cingular's wireless data network. Each device is assigned a static IP address. We also have a Frame relay through Cingular that all wireless devices connect to our network via. I have 5 IP addresses that I can use. I am using one, 166.212.xxx.26 and then NATing it to my internal IP of 192.168.200.100. This is an internal Citrix server. That is working fine.
I am now setting up mobile device sync on my Blackjack. I setup another NAT on my switch connected to Cingulars frame link that Nat's the external IP of 166.212.xxx.30 to internal 192.168.200.110. My syning is working great without ssl.
I am now trying to setup syncing with ssl. I am getting an error that says "your certificate does not match the name blah blah..." The reasson for this is because on my device, I am telling it that my mail server name is 166.212.xxx.30. My server certificate is saying it's name is companymailserver.com.
I am guessing that Cingular needs to put a host record on their DNS server that says 166.212.xxx.30 is companymailserver.com. I can then plug that value vs the external IP address into my device and everything will be happy. Am I correct???
