OWA 2007 External Access

Hi,

I am having a few issues setting up OWA.

I have it working internally ok with no problems at all.

I am unable to access it however from outside the LAN?

For now I just want to access it so have disabled SSL - can anybody tell me what DNS changes etc need to be made (if any) in order to access the page?

Thanks,
Toby

I said "So from outside your network navigate to http://a_record_you_setup/owa obviously if your using SSL it would be https"

You have closed the question stating you used HTTPS which is what I had said in this comment.

Right from the beginnng you had said that you had disabled SSL which is HTTPS so I did not continue to mention it.

You need to forward port 80 if your not using SSL and port 443 if you are from your firewall/router to the internal IP address of your exchange server.

You then need to setup an A record in your external DNS for something like owa.domainname.com and forward it to the external IP of your exchange server.  Find out what this us by going to http://whatsmyip.org

I have setup the port fowarding already.

I have setup an external A record which point to the external IP of our router - then the ports forward?

should this be all I need to do?

Thanks,
Toby

When I try that I get "HTTP Error 503: The requested service in unavailable"

All the necessary services are running.

On my router I have to select the ports to and from the forward? E.G from  the incoming ports to the router (1111) then forwarding to internal address and port e.g 192.1.X.X and port 80 for OWA?

I have this working in other areas of the system and it works well.

Does that make sense?

If you just goto http://A_record_you_setup/ what do you get?

Also goo http://whatsmyip.ord and get your external IP address then goto http://ipaddress/ what do you get?

When I do either of these it takes me to my internal router?

I have a sub domain setup which links to the external IP of my router.

So should I use:-           http://office.semplice.co.uk/owa

you need to do it from outside your network?

If you get the router from outside your network then port forwarding is not configure properly.

When I try that I just get the 'HTTP Error 504: Gateway Timeout'?

Port forwarding is working ok because we have a number of users that are accessing apps remotely.

Thanks for your help so far!

Make sure port 80 and 443 are both forwarded from your router/firewall to the internal IP address of your exchange server.

If it's already configured remove it and recreate the rule.

I have set that up but still doesnt connect to the site?

It seems to find the page, gets stuck on waiting for the page then crashes with the HTTP 504 Error?

I am also running TMG on the network but cant see any issues with that.

I have resolved the problem.

I tried https and it worked, as well as restarting the IIS services?

Thanks for your help.
