    Default Unable to logon

    Not sure why this is happenning. Currently doing a trial run ZCS, on RH 5, ZCS 6.10. From within our network I can access ZCS and Admin Console, outside our network I get the logon screen but when I logon in I get cannot display page. I have opened the firewall for HTTP services for my test server. So how can I get the logon screen but it fail when I click Logon In, like it cannot find the page ? Also I can internet email but ZImbra will not receive internet email. I'm sure its some DNS issue. Network Solutions is where the DNS is parked (mailpca.us). I set up DNS the same way I have my current email solutions domain setup.

    Thanks

    Go to the Split DNS article and read-up on what's necessary if you're behind a firewall and.or a NAT router, your hosts file also need to be correct and details for that are also in that article.

    Default Dnsmasq Appears To Be Correct

    I read the article on split DNS and all the files appear to be correct. However my DIG answer TTL value is zero, is this correct ?

    They may well be but just for confirmation let's see the output of all the commands from the 'Verify...' section of that article.

    You're correct, of course, those DNS results are OK. Do you have SElinux enabled on this server?

    I missed your question on TTL earlier, I don't believe that zero will be causing you any problems related to the issue you're experiencing but you may like to set the defaults to these: DynDNS.com - Support -- Knowledge Base -- DNS Caching
