Hello,
Thank you for contacting us.
Apologies for a delayed response.
I'd like you to try setting up your WAN port as LAN. The instructions on how to achieve this are provided in the following link and are compliant with RUT2_R_00.07.01.4 firmware version: https://wiki.teltonika-networks.com/view/Setting_up_WAN_as_LAN.
Next follow these instructions to set Bridge mode:
Make sure that WAN failover is turned off in Network → Failover page and mobile is set as main WAN in the Network → Interfaces page.
Make sure that DHCP server is enabled on menu Network → Interfaces → LAN.
Then in the Network → Interfaces → Interfaces:MOB1S1A1 page select Mode: Bridge in the mobile configuration section. You will then see an additional configuration field for entering a MAC address appear. Enter your PC network interface MAC address, use colons to separate digit groups.
Set your PC to obtain IP address automatically. Go to the Ethernet Settings → Change adapter options → Ethernet NIC properties → Internet Protocol Version 4 (TCP/IPv4)→ Obtain an IP address automatically.
Reboot RUT device.
Wait about 5min., that RUT fully boots up in Bridge mode, then re-enable PC network interface or reboot your PC.
Keep in mind that If you have configured Bridge mode you will not be able to reach your router. To access RUT Web UI in Bridge mode:
You'll need to set up a Static IP address from RUT LAN IP addresses pool range on your PC.
Reboot RUT device.
Best regards,
Shadrack.
