Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3.2

I am trying to set up a second Dynamic DNS entry on my ER605 using custom DNS, but the interface dropdown is completely greyed out and I am unable to select my WAN interface:

 

 

Is this a bug? I don't understand why I can't have two Dynamic DNS entries on the same WAN.

 

I found an older (locked) thread from a few years ago here where someone had the same issue: https://community.tp-link.com/en/business/forum/topic/513332

 

Thanks in advance for any help!

you are right, you can only have one on each wan interface, why it is limited to only one I don't know

Thank you very much for confirming!

 

Seems strange to me that this isn't allowed, I wonder if this is a bug or a design oversight?

 

I don't see why it shouldn't be possible to set up multiple DDNS for a single interface - as far as I understand it all the DDNS setup does is basically make CURL requests, so I can't see a technical reason why multiple for the same interface shouldn't be allowed?

 

Perhaps the developers thought nobody would want multiple domains pointing to the same IP? I am trying to run two services with two subdomains pointed at my router, so this functionality would be very useful for me... I can't imagine this is too much of an obscure usecase? Especially if you were doing something like virtual hosting for a bunch of websites.

Hi  @shorthouse06 

Thanks for posting in our business forum.

May I know if the second DDNS entry is from the same provider or different one?
