Can not access web site by using External IP

[ckevin]

Dear All,

I have a little problem of access my website. My setup as follows:

I have one IIS server (192.168.0.100) connected to LAN, and I have a record to map "ABC" to 192.168.0.100 at the internal DNS Server already, so every machines on LAN can access the site by typing "

http://ABC"

or "

http://192.168.0.100"

internally. Totally no problem.

This web site is open to public too. I mapped a global static IP (let's say 123.123.123.123) to 192.168.0.100 at the router, and all the clients from Internet can access the web page by typing "

http://123.123.123.123".

Totally fine.

My problem is why all the internal machines connected with LAN can not connect to this web site by typing "

http://123.123.123.123"

at IE.

More information here:
1) I tried to ping 123.123.123.123 at a internal machine, there is reply.
2) All internal machines have internet access.

Thank you very much.

Your router doesn't support local loopback. Replace it with one that does if this functionality is important to you.
