Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.2.5

I just bought an ER605. I have it set up as a double WAN failover. The first line is FIOS, and if it goes down, I have a cable backup provider.

 

Both networks have a public - non-static - IP. 

 

I found the DDNS settings for both lines separated, but I can not find a combined one. 

 

I want to be able to address my network via the same DDNS no matter what network is active. I completely understand that this only makes sense in failover mode, not in load-balancing mode. 

 

Using a DDNS software on a PC is not a solution, as it is too slow compared to a router.

 

The routers I used before all had such a fallback DDNS option.

 

Did I not find it or is there no solution?

Hi @StephanK 

Thanks for posting in our business forum.

This is more of a config for your network, not a router issue.

We do not support the same DDNS for both lines set for your router. Natively. 

If you need to alias for the domain(DDNS you use), you should contact the vendor for more details on such a service.

Thank your for your response and the info that you do not support DDNS for the failover group. 

 

I disagree this is a network issue. Others, such as Asus and Pfsense, support it, so I will return the TP-Link and use Pfsense.

Asus' native firmware support this? I use Asus back home, but I don't recall it supports DDNS failover.

 

That'll be great. Pfsense offers way more flexibility for your network if this is a must-have.
