MásMóvil, their ZTE F680 and a Synology [now works, see update]

Hi there,

so today I got a nice neat new internet connection for my place. As I am currently living in Spain, I signed up for a fiber connection from MásMóvil, a big ISP here. They offer symetric GPON connections of up to 300MBit/s for as little as 40 EUR a month. I was super excited as I signed up for that. The technician came two days after signing the contract and pulled a fiber cable from my apartment to the distribution panel in the building. That all worked well. Internet is fast, as advertised.

As CPE they hand out a ZTE F680 unit with Gigabit LAN ports, a PON socket, some USB and phone stuff. Pretty standard. Wifi is to AC specs with advertised 1750 cpacity. Anyway, as soon as I removed my trusted LEDE router and put that white box in it's spot, I connected my ethernet devices, changed the wifi password, IP ranges, .... the usual stuff

Now comes the strange part. My XPenology seems to be able to get an IP from the DHCP but I am not able to ping it or connect to it. I tried multiple machines, different LAN ports, wifi network. I also gave it a manual IP address. No chance. As soon as I connect it back to the LEDE router I can access and use the NAS as usual. It seems like the ZTE doesn't like the XPenology N54L HP Microserver. I have found some other people complaining about this as well on a Spanish forum and it seems as there is a firmware bug in the ZTE which prevents the Synology to properly connect to the network. All packets seem to be dropped.

My temporary solution for now is that I am using my secondary LEDE router now as a common access point outting it on the same subnet as the ZTE router. The LEDE is the DHCP server handing out the IPs with the ZTE's IP as default gateway. That works and I can connect to my NAS from my other devices. If I hardwire myself (or connect to the ZTE wifi) I am not able to access the Synology device.

The firmware of the ZTE F680 is V4.0.10 P1T3 ( Hardware version 4.0 )and the XPenology is DM 5.0-4458 Update 2. I am not upgrading this as it stays in my home network only and is not connected to the outside world. Never change a running system ;-) So if you experience the same issue with the ZTE gateway, let me know. Maybe you have found a solution?

As my Spanish is not very good I will not bother with the support as they would probably have no idea anyway.

UPDATE:
My TP-Link Archer C7 died the last week and I was forced to use the ZTE CPE as Router again. Everything is working, the Synology works fine on the LAN ports. There has been some updates to the firmware of the ZTE, the current one now is:

Software VersionZTEGF6804P1T6
Boot Loader VersionV4.0.10
So they have fixed something since I tried it last time. Good enough!
