I have owa working securely internally, but I cannot get it working externally, if you have the time to help I would appreciate it very much

Here is the Mozilla error

The connection has timed out
    
    
    
    
    
      
      
        
The server at mail.noahwebster.org is taking too long to respond.
      

      
      

   *   The site could be temporarily unavailable or too busy. Try again in a few
         moments.
   *   If you are unable to load any pages, check your computer's network
         connection.
   *   If your computer or network is protected by a firewall or proxy, make sure
         that Firefox is permitted to access the Web.

Here is IE error






Internet Explorer cannot display the webpage






Most likely causes:
    You are not connected to the Internet.
    The website is encountering problems.
    There might be a typing error in the address.




What you can try:
Thanks

Terry

So are you using any reverse proxy (ISA/TMG)?

No, I am not using any proxies.

My condfiguration consists of a

Cisco PIX 501 routing email to
Barracude 300 email filter routing email to exchange server with port forwarding for port 443
Exchange 2003 providing owa

I dont want to post my pix configuration, incase it reveals vulnerabilities, but if you could tel me what it should have inside the configuration that would be greatly appreciated.

I am a beginner at cisco configuration, so be kind

Regards

Terry

I also checked the IIS management logs, and it appears that no external traffic is reaching the IIS server.

Thie makes me think it has to be something with the firewall

I think you should recreate the port forwarding from your Barracude to TCP/25 towards Exchange and then create a port forward on your Cisco for OWA to Exchange on TCP/443

The baracuda is only port forwarding port 443, if I port forward port 25 wont that stop the baracuda from filtering email?

I dont totally understand why I would port forward port 25
Could you elaborate for me

Thanks

Terry

Mail Flow normally travel by SMTP Port TCP/25

OWA is using HTTPS on TCP/443

What Im thinking is that your configuration might be confusing the systems somewhat.

Just a guess though.

I appreciate the help. I did check with the ISP. no port blocking in place. I have two mx records on file pointing to the external ip address.
The cisco pix is configured as such for port 25 and port 443

fixup protocol smtp 25
access-list 101 permit tcp any host 70.97.155.50 eq smtp
access-list 101 permit tcp any host 70.97.155.50 eq https
pdm location 10.1.1.10 255.255.255.255 inside

10.1.1.10 was the exchange server address before we went with baracuda, but now it is the barracuda ip, and the exchange server is 10.1.1.7. I did this so I didnt have to reconfigure the pix, because as I said before. I am new to cisco routers

I hope this information helps, and that i didnt leave anything critical out

Regards


Terry

When I try to telnet into the server I get a connection failed

As I stated previously, Im not familiar with Cisco PIX but it looks like you with you config is telling the Cisco PIX to forward 443 to the Barracude which of course is wrong and would be consistant with the problems you are experiencing.

Please try to figure out how to configure your PIX to add a new forward of 443 to your Exchange IP and remove the forward pointing 443 to Barracude.

Port 80?! I really hope you dont allow external access to OWA through port 80, are you?

I think it is due to your proxy using. Pls try anther proxy IP address.
