B818-263 - How to configure Dynamic DNS Services other than the preset DynDNS.org, No-IP.com and oray ?

Hi Huawei,

I have aquired a "Huawei B818-263" aka "Huawei 4G LTE Router 3 Prime". 

While dynamic DNS works well with No-IP, I want to use another service of my choice. The ones preset by Huawei are paid services and / or Chinese, which is not what I want ( my Chinese is a bit wanting ;-) )

Likewise, when adressing the WAN IP I can _only_ reach the Web-UI of the router, but no device in my local network.

I have tried both, "Virtual Server", as well as "DMZ Settings".

Asking for Email-Support achieved two Emails from Huawei Support with useless information ("tell us what you try to achieve" and "Ask Vodafone, the software is provided by them".

Answering these nonsensical messages resulted in bounces, telling me "<mobile.de@mail01.huawei.com>: host mailmx05.huawei.com[103.218.216.217] said: 550 5.7.1 Sender IP in realtime blacklist client [194.25.134.22] blocked using rbl.skyguard.cn (in reply to RCPT TO command)

How can a recipient you just sent email to be blocked from answering ?

So, the main issue seems to remain: Is Huawei able and willing to provide support for it's products ?

N.B. I bought the item from Huawei through Amazon, no mobile phone provider has anything to do with it.

In case you want to track the device: The serial number is VNN7S20518002678 and Huwaei grants warranty for it.
