TRB500 limitations of bridge mode - and what to do

[clive.simon]

Hello,
Welcome to Teltonika Networks Community !
Kindly refer to the below posts for a better understanding of Bridge and Passthrough modes.

Differences with Mobile Modes (NAT, Bridge, Passthrough)

Hello, I’ll go over each of the modes and explain a little about all of them: NAT mode This is the most commonly used mode - it handles L3 routing, as well as NAT (Network Address Translation). In this mode, managed Teltonika products can support more than one LAN client, by providing each of them with a private IP address. If you have a public IP address on your mobile interface, port forwarding can be configured to forward specific ports to LAN clients. Some people also treat NAT as anoth…

The main difference between Passthrough and Bridge is that in Passthrough, the router’s DHCP Server still works and the regular LAN interface is still up, allowing clients to connect to the router’s local network as usual and the connected devices will have WAN access too, while Bridge mode disables all of these features and simply gives the a single specified device its WAN IP address, but if DHCP is enabled the devices connected will only have local access.

The issues you are facing can be resolved by using passthrough mode instead.

Moving further on passthrough mode is used when you still need a local network and connectivity to our router - Like in the case of Helium Miners Providing connectivity for Helium miners using the RUT240 - Teltonika Networks Wiki

Also an important point, i would advise you to retest using the latest FW TRB500_R_00.07.06.1 , as it comes with a patch that greately enhances Passthrough and Bridge modes.
