I want to setup a host at home.
I connect to the ISP by router and a cable moderm. There are totally 2 PCs connect to the router.
Now by using IIS, I can visit the DNS registered at DynDNS by from the same PC. But I cannot linkup to the DNS in office.
Attached is the port forwarding that I made so far.
Any suggestion?

adding to SteveJ, check the logs on your router.
if you tried connecting to the site it will have some kind of a record - either blocked or forwarded. that will tell you if the problem is
a. public DNS is incorrect
b. your router block the connection
c. your router accept the connection and forward it
if option c is the correct one then you should go to SteveJ's question and chekc the firewall on the 0.101 IIS machine
If I understand correctly, you are able to access your website from home using https://yoururl.dyndns.org
If I'm misunderstanding your question and it is a problem with port-forwarding, have you tested the port-forwarding by trying to access your website using your modem's external IP address?
I've used DynDNS in the past, and I found it took a several days for the DNS records to populate to the other DNS servers on the Internet. If your work computer uses a different DNS server, it could be that it doesn't have a proper record yet.
Hi SteveJ,
You are correct, but after I turn off the firewall, it still not work.
There are 2 PCs connected to the router, from the other PC, I can linkup the host page.
After I clear the log and try to linkup from outside, there is no new message in the log.
I have opened all the optionals for log as below.

So . . . your router has a public IP address and your web/host has a private address (is that the 192.168.0.101 address shown above?) So someone wanting to visit your web page would send a request to the router public IP address (or the DNS name you've registered to that IP address) on port 80 which you would then forward to port 80 on the 192.168.0.101 web host. So you have a DNS name registered to the public IP address of the router and when you try to reach your host from a location other than your home you can't reach it?
Do you have a firewall turned on that might be blocking inbound requests to port 80?
Good luck,
SteveJ
