Exchange 2010 OWA Setup

[support@coffsccs.nsw.edu.]

Hi there all,

I was just wondering if anyone knew how I set up untangle so that staff can use Exchange 2010 owa externally?

I port forwarded 443 to the exchange server but that didn't work. I am very very green in this area and last time I did it was with ISA server back in 2003. So any advice or pointing me to any sites you may know of that can help with this would be much appreciated.

We only have 1 Exchange server and 1 untangle box.

thanks
Darren

all you need to do is open 443 and it should work, did you properly set up the rule?

do you only have 1 external IP address?

your rule should be something like (not using advance mode)

Protocol: TCP
Port 443
LocalIP - IP of your server



can you access the OWA internally on your network?

https://mail.localhost/owa

or what ever your internal IP is for the mail server?

Did you set up the properl URL for external access?

how are you accessing the OWA externally?

https://mail.mydomainname.com/owa

?

Most likely the issue is you need to go into UT admin interface and change it from using port 443 to another port (8443, or any random port is fine, just remember what it is, as you will have to use that to access externally in the future), then your port forward should work. I assume currently when someone tries to access externally they get directed to the UT login screen (if you have external admin enabled)?

Make sure you have defined your internal and external addresses in Exchange

Chances are its because you have not moved the admin port for untangle of 443. An if its not enabled external, it could still be causing issues, as it over rides port forwards by default.

Yeah your right. Every time i meant o https it was going to untangle admin.

I tried port forwarding port 443 to an internal IP address which exchange is on but then whenever any1 went to a https site it would come up with file or directory not found error.

Realised that in the port forwarding I hadn't put in a source interface, so you can imagine the problems it caused at work... *sigh*

I will try it again and see how I go.

thanks for the responses.

I can access owa internally using mail.xxxxx.xxx.xxx/owa but when I try the same externally it comes up that explorer could not find the web page.

I have put in a port forwarding rule

Protocol: TCP
Source Interface: External
Port: 443

New IP: 192.168.0.2
Port: 443

but still not able to get there. Basically I want users to click on a link on our website that then takes them straight to the OWA log on page. so if they type in say mail.mydomain it will then go to OWA site and then they can log on.

did you change the administrative port for UT to something other than 443, do that.

Port Forward in Advanced mode

Destination Address: WAN IP to publish on here
Protocol: TCP
Destination Port: 443

New Destination: IP of Exchange
New Port (just clear this, why it defaults to 80 is beyond me it should be EMPTY all of the time)

This forward will only work if you have moved remote admin as has been suggested multiple times. You can only use a given port once, 443 is burned on all IPs on Untangle for remote admin. You either move it or get crazy in the packet filter.
