DynDNS

Athena

Hello,

I configured a DynDNS on an USG40.

The IP of the WAN port is correctly forwarded, but... it is the local WAN port addresse (192.168.1.x).

Is it possible to send (to the DynDNS provider) the public IP of the router beyond the WAN port ?

Thanks in advance for your help.

No the DDNS uses the interface IP as the IP it sends the USG40 must have the WAN IP to send the WAN IP.

Athena

OK, thanks for the answer.

But it won't help...

 Hi @Athena

When the USG is behind a NAT router, you can set the IP Address to AUTO, instead of Interface.The DDNS server checks the source IP address of the packets from the Zyxel Device for the IP address to use for the domain name. You can set to auto in this scenario, but the options available in this field vary by DDNS provider.

Create a DDNS profile at “CONFIGUATION > Network > DDNS”, and set to “AUTO” at IP address.

Its too bad No-IP don't have that Auto option.

Yes, some DDNS provider does not support Auto option.

Their is a No-IP software client that detects the WAN IP so may be its possible? That or this still would work so that I can link it to OPT but go out VLAN443.

Hi @PeterUK ,

We just found that NO-IP does support IP address = Auto. I will put this thread in idea section.
