DNS across a VPN tunnel
Dear Experts,
My company has a production environment (domain name = corp.company.com) and an office environment (domain name = office.company.com). In the production environment, we have a set of Cisco ASA 5515 firewalls (managed by our datacenter) and at the office we have a set of Sonic Wall’s (managed by me). I worked with the data center engineers to setup a site to site IKE tunnel between the sonic walls and I can now remote desktop and communicate with servers in the corp domain from the office domain and vice versa with no problems.
The problem is I can only access my servers on both sides by IP Address. I realize there needs to be some form of DNS setup between the domains that I don’t fully understand. I was able to setup a secondary zone on one of my office DNS servers that pulled down a copy of Corp. I can now use a remote desktop session across the tunnel by using – computername.corp.company. com. This works from the office to corp but not vice versa. Do I need to do the same thing on the Corp side or is there just a better way to set all this up.
Currently, all my servers are Microsoft Server 2012.
Would appreciate any and all help.
Thanks
John
