Have you already verified your router is being assigned a public IPv4 address?

If the WAN IP address happens to be a private or otherwise reserved IP address, then you can't just simply connect to your router from the Internet.

 

Private/reserved IPv4 addresses are those within the following address ranges:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
100.64.0.0 - 100.127.255.255

 

Aint domain name and public ip the same thing in this case? If not, how can I assigned a public IPv4 address? Now I have a domain name of the form ******.hopto.org and an address of the form 93.73.99.***

@n00b-2005 

 

No, they are not the same.

 

Anyway, go to the Status webpage of your A5 and check the WAN IP address shown there.

If it is 93.73.99.***, then you should be good to go and your problem is caused by something else.

However, if it's not, then it can't work this way and you will have to do more to make it work.

Yes, WAN IP has the form 93.73.99.***

@n00b-2005 

 

Good.

 

Have you already tried to access the A5 router from the Internet by typing http://93.73.99.***:80 ? (make sure the IP address is indeed the one of your A5's WAN and the port is the one you configured in the router)

 

By the way, what does your Internet browser say when it fails to connect? Most modern Internet browsers will give you a ton of warnings before they actually let you visit a non-secure website over the Internet.

Yep, I really tried, but to no avail. The browser says that the page is not available, i.e. ERR_ADDRESS_UNREACHABLE

One more thing you could try is to change the "Web Management Port:" in the A5's Remote Management configuration page to some other number, in case that your ISP is somehow blocking port 80.

For example change it to 8080 and then try to access you router via http://[your WAN IP]:8080

 

Else I have no more ideas.

 

Changing the port number, alas, did not give the expected result :(

Perhaps it's very unlikely, but can you check if you may have activated the DMZ host feature (in the menu "Forwarding") at some point and later forgot about it? 

 

DMZ host feature (in the menu "Forwarding") is turned off.
