Install asuscomm on new Asus RT-AX86U Pro

[xlarge]

Last time install asuscomm was 15 years ago and I remember not what I did.
The router is prepared and setup everything incl. OpenVPN server connected to my home net and setup via laptop. New from shop with 192.168.50.1 and laptop used 192.168.50.xx during the setup.
I have two options:
1. Install a new asuscomm via the laptop on the same connection.
2. Replace my home router with the new one and install the asuscomm. (With direct access to the ISP)

Can both be used and work when the router is moved to the remote place (300 km away)?
Can I import my old cert-file from the old remote router (AC68U). If not, how do I get a new one?

For general Asus router DDNS setup, see the following Asus support document if you haven't seen it already.
[Wireless Router] DDNS introduction and set up

Note that there have been several recent discussions by others who express dissatisfaction with Asus's free DDNS service. They indicate frequent service outages. One can use the forum search feature to find those recent discussions.

I knew this, but my question is if I can use the temporary local connection or must use Host ISP when install asuscomm.

When you set up a DDNS you need a connection to the internet. DDNS will then create the records that will point your hostname to your WAN IP address. When that WAN address changes, it'll update the IP that the hostname points to. Provided you have access to the internet with a unique WAN IP it'll work. So you could set it up with the router connecting to the internet using your Mobile phone (subject to that unique WAN IP), and then switch to a wired WAN connection, and it'll just work!

Reading between the lines I believe you have an old router which uses the free Asus DDNS service (what you call asuscomm). And you have a new router that you want to set up DDNS. You can use your old DDNS name on the new router but you first have to de-register the Asus DDNS on the old router. This can be done on the old router from the GUI. If there is no option to deregister the DDNS you may have to upgrade the router firmware which should have the tool to deregister the Asus DDNS name. Then you can use the "old" Asuscomm DDNS name on the new router.

Thank you very much. That is much easier for me.
The second question, what with the certificate (cert-file) which I exported from the old AC68U, can I use (import) it to the new router thereafter?

From experience both can use a separate DDNS. In that case you do not want to "transfer" old to new, but simply create a new one on the new router.

Thanks, I have decided to do so because I am looking for the most easy / simple way to change fysically from old to new router remote - by one of my children. Because I am not able to do it my self remote.
And, if anything go wrong we have the option of replace the old router with the old not "deregistered asuscomm".

Certificate?

 

[jzchen]

The certificate will not transfer. You can use the one on the new router. Depending on remote or local access the DDNS one expires in 90 days, the local one expires in 20 years from manufacture. (Don't even need to renew any local certificates, for example the default one my AXE16000 created after hard reset expires 2044 +/- one year)...

The following Asus support document may or may not be relevant to the discussion on moving the DDNS from one Asus router to another.

[ASUS DDNS] How to transfer ASUS DDNS to new device ?

 

[xlarge]

Done. Success! Got the certificate automatic.
Just one more detail, "Forced update interval". I have earlier used "1", but the router came with default "21". What is preferred?

I actually haven't seen that setting before, to be completely honest. (Is that in DDNS? From Google search it is).

If so then under Advanced Settings -> Network Map

click on the Globe symbol/image towards the top center.

On the right column there's a "Lease time" which I believe is set by your ISP. I would set it based on/to match that.

Sorry I should be more at the point. Here is a pic of it at the DDNS page and must have to do with asuscomm.

It appears to be a forced check even if the IP hasn't changed. It is typically not necessary to change it unless you are having problems with remote access I suspect.
