Hello Everyone,

My issue is that al of my NTP request through my NX200 are failing.

I'm actually from the Netherlands and on vacation in Spain right now.

I bought my Archer in the Netherlands and bought a prepaid SIM here in Spain.

So far the internet connection is working but when i try to sync any device with NTP it fails, even the NX200 itself.

I have no wired WAN available so i cannot test if this would help.

So far i have tested the following:

- Tested devices through WIFI sharing on other mobile devices: NTP syncs

- Tested carrier blocks NTP services (switched SIM to mobile device): NTP syncs

- Opened port 123 (ALL) and 1023 (ALL): NTP won't sync. 

- Completely turned of firewall in NX200: NTP won't sync.

- Turned of all ALG options: NTP won't sync.

- Turned on DMZ to PC: NTP won't sync.

- Tried turning off NAT but then carrier seems to block acces: NTP won't sync.

- Tried different carrier APN profiles (2 working for Orange Spain): NTP won't sync.

- Tried over 8 different time servers incl. Apple, Windows, Google, (es.)pool.ntp.org, etc.

So with al these tests i'm kind of stumped why this still won't work, i hope you guys can help a man out.

Love to hear you suggestions and if any information is required, let me know!
