Linksys BEFW11S4 Loopback?

    Does a Linksys BEFW11S4 router have loopback capability?
    If not, I must be out of my mind.

    I am unable to view my websites from the LAN side when I try to go outside first, such as http://www.mysite.com. However, I was able to do this at one time and now I cannot. I do not know what might have changed. The websites are accessible to outside users from the WAN.

    To compensate for the change, I have modified the hosts file on my development machine in order to test. This is another indicator that something has changed as I did not need to do this before. Any ideas?

    I have a Comcast cable connection through their cable modem to my Linksys router. The Linksys forwards port 80 requests to the web server.

    Comcast provides a dynamic IP which is monitored by a client program on the web server that notifies No-IP.com when it changes. No-IP then redirects my website address to the new IP. In effect, keeping my website address static. I have been using this for two years.

    The web server computer is cable connected to the router and it has a static internal IP. The operating system is Windows 2000 Server with IIS 5.0. web server. I do not run a software firewall, but I do run a McAffee Virus Scan.

    Your help is greatly appreciated.

    Check the "Filter Internet NAT Redirection" option in the router.

    Thanks to 4Access for the response. However, I have tried this setting both ways. Actually, there is not a checkbox for this option. Rather, they are Option Buttons labeled "Enable" and "Disable". Seems like a moot point question, but which option allows loopback?

    I asked the question above before reading the "More Info" links provided by 4Access. The answer is Disable the filter to allow loopback. As I said, I have tried this both ways.

    Loopback did work at one time. I upgraded the firmware to the latest version 1.45.10, but still no loopback. Unless someone knows of some other reason, I fear the router hardware is faulty.

    Thanks in advance for any ideas or suggestions.
