Don't we all love sharepoint, there are always questions. I have a couple about setting up for External Access to all employees so this can be used outside the local network.
But first I was doing this on local dns to check and make sure the external names would work when selecting links on different pages.
Then my second question would be do I need one certificate for each site name or one certificate with both site names?
Things that have been Done
IIS manager the sites are set for windows Authenication.
I have alternate mapping setup in sharepoint
In IIS manager
The each local site has a binding for mysite.domain.org
In Local DNS Forward Zone
Both local Sites have A records for local.org attached to Server IP (which work)
PTR records created for mysite.domain.org pointing to ip.local.org
CNAME record created for mysite.domain.org connecting to mysite.local.org
CNAME record created for sharepoint.domain.org connecting to intranet.local.org
When I use nslookup mysite.local.org shows Server IP and the website works
nslookup on mysite.domain.org resolves mysite.local.org, ip, and aliases same results with intranet site
but when entering mysite.domain.org in the browser it doesn't show the site same with sharepoint.domain.org
It's pointing to the correct local DNS , I've done dnsflush & register, IISreset on Sharepoint, deleted temp content/cookies from internet, added to trusted sites.
Any help is appreciated. What steps am I missing.
