I followed the workaround and am now able to access my company web from where ever I am at.
Make sure the following ports are mapped to the sbs server
tcp4125
tcp444
and check the web site security and make sure you are not blocking all ip addresses…
WORKAROUND
To work around this issue, edit the HTML code for the default Web site to make the My Company’s Internal Web Site link work over the Internet. To do this, you must replace the internal http://companyweb link with the following external link:
https://FQDN_of_SBS_Server:444
This external link works correctly both over the local network and over the Internet.
Note The Windows SBS 2003 Setup program cannot configure the My Company’s Internal Web Site link in advance for external use, because neither the server’s fully qualified domain name (FQDN) nor its external Internet Protocol (IP) address is known when you run the Setup program.
To edit the HTML code, follow these steps:
1. Click Start, point to All Programs, point to Accessories, and then click Windows Explorer.
2. Expand My Computer, expand Local Disk (C:), expand Inetpub, and then click wwwroot.
3. In the right pane, right-click the Default.htm file, point to Open With, and then click Notepad.
4. On the Edit menu, click Replace.
5. In the Find what box, type http://companyweb.
6. In the Replace with box, type https://FQDN_of_SBS_Server:444.
7. Click Replace All, and then close the Replace dialog box.
8. On the File menu, click Exit.
9. Click Yes to save your changes.
When you access the Welcome page on the default Web site over the Internet, and you then click the My Company’s Internal Web Site link, you are now redirected to your company’s internal Web site.
