ER605 second WAN Port is connected but doesn't go online
Hi everyone,
Have an issue with my second internet source.
Just had one internet connection (DSL Modem) which is connected to ER605 WAN Port and is connected via PPPoE with the Modem. Due to some bad weather this internet connection got offline for some days and I seached for a second internet line.
Installed a ZTE 5G (MC801A) with a Simcard which should be my second source.
Activated second WAN/LAN1 port for WAN activities, configured it as Dynamic IP (IP should be sent by ZTE router which acts as DHCP Server). On the ZTE I have done DMZ for the ER605 so that ports shoudnt be an issue.
Internet (fixed IP) <-> ZTE Modem/Router (10.100.10.0/24) <-> ER605 (10.110.10.0/23)
I managed to get ZTE Router with ER605 connected, so ER605 gets IP address from ZTE and has the state "connected" but, unfortunately the "online detection" shows this source as offline, even though I can access from ZTE router directly to Internet (if I connect eg my phone or notebook directly to ZTE router)
Does anyone have an idea what I am doing wrong? Maybe a DNS issue?...
If some infirmation are missing, please let me know.
thx
