Question for SharePoint

I have a SharePoint server that we access internally via a URL.  We have established an external IP address for it and opened port 80 through the firewall with a NAT rule to translate from the external IP to the Internal IP of the server.  When I type the server URL in my browser, substituting the server name with the external IP it prompts me for a log on as it should, then I get error 404 page cannot be found.  If I use the same URL internally, using the server name it logs on normally.  Any Ideas?

Hi,
are you sure you get a 404?
Can you try to run a proxy tool like Fiddler or Firefox with Firebug to track the requests and response codes?
Which element causes the 404?

Thanks and HTH
Rainer

Can i suggest that publishing this via port 80 without a firewall such as forefront is not a good idea. A sniffer will be able to pick out your username and passwords from the traffic flow.

If i were you I would be looking at using SSL at a minimum.

If you do decide to continue on with this you will need to understand AAM's as by default Sharepoint will listen the address http://servername. Clearly this will not work when coming in from the outside - you need to setup an AAM for http://servername.company.com.

Have a quick look at this page to understand how they affect a sharepoint implementation

Thanks for the info on SSL, I will change that for sure.  I cannot access the link you posted.  It gives an error  "the page cannot be displayed.

I am having our ISP change the port on the firewall  then I will setup AAM.  Thanks, I will let you know.

I had the port changed to 443 for SSL and now I can't get to the server, is there something in IIS and SharePoint I need to change?

Yup,

You will need to create an alternative access mapping. This will be the external address you have published.

Regarding ssl. Are you planning on setting up a reverse proxy or directly hit the sharepoint server? If you decide to use a reverse proxy like Microsoft Forefront or Microsoft ISA then you can use a port redirect from 443 to port 80. Very easy :-)

If you are hitting the server directly then setup a certificate. http://technet.microsoft.com/en-us/library/bb964105(v=office.12).aspx

Without a proxy/firewall I would keep an eye on the traffic. Some naughty ppl could hit your server with a DDoS.

Hope that helps
