Hi,

I get a "Referer check failed"  error when trying to access my router's login page via the DNS name (A record)  from the outside world. It works alright when I'm accessing it via IP.  

Details:

I allowed remote management for 0.0.0.0/0 and connected from another location.

I setup A record to point to our external IP. 
I used Safari and Chrome. 
I don't use DDNS. 

 

Best,
Yevhenii

Hi @YKurtov 

Thanks for posting in our business forum.

Thanks for the reply and clarifications  @Clive_A . I'll keep an eye on the firmware updates. However rebooting the router requries half a day of prepearing services for even a second of downtime :\

I'll pass on that. Accessing the device by IP is not a big issue for now. 

 

However I can't connect to the web admin panel anymore. I guess that's a completely separate topic and I'll open one now

No. I mean some users reported that they can use DDNS to get rid of it.

Just to see if you can refer to this discussion.

 

For the referer check, this is a feature added some time ago to address the security concerns from our contract users.

We later received reports on this, but we will fix this in the future firmware with an option to enable/disable it.

Hi @YKurtov 

Thanks for posting in our business forum.

If you set up the DDNS, will this disappear?

This has been reported. You gotta wait for the firmware to fix this.
