Setting up a site to be accessed both locally and externally

Current Situation:
We have an A Record setup for clients.abc.com to point to our external IP address of 273.1.2.3. If you are NOT on our network, you may go to clients.abc.com and it pulls from our Linux server located locally on our network at 192.168.1.7. If you ARE on our network and you visit clients.abc.com, the user will receive an page load error.

Desire:
We would like to access clients.abc.com both locally and externally without any issue.

Necessary Specs:
RedHat Enterprise Linux v5.7

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Create an internal DNS zone that points to the internal IP address?

Can't you set a local DNS record in your network to redirect clients.abc.com to 192.168.1.7?

A few options are available:
1.) You need an internal DNS server with an A record pointing to the internal private IP.
2.) Add a host file entry on your internal machines for the internal IP. (easiest option)
3.) Add a conversion rule in your firewall for LAN machines looping back in to the private IP.

Hope this helps,

Correction: Host file is easiest only if you do not have an internal DNS option.  Sorry about that.

Thanks a lot. We have several Windows Server 2003 in place so we went ahead and had DNS settings setup to redirect them locally. Thanks again.
