Thank you for asking this question in the support community. When you get a chance, I think a network diagram or additional explanation would be beneficial, as I'm not sure I follow the application.
You cannot bridge the two Ethernet ports. Therefore, Eth 0/1 and Eth 0/2 would have to be in different IP subnets. It depends on the overall application, but if there is a switch that is plugged into Eth 0/1, then the technicians could plug their PC into that switch and access the WAN. Furthermore, depending on how you design the network, they could also plug into Eth 0/2 (with a different subnet scheme) and be able to access the network that way, as long as the routing, etc. was setup properly.
Please, provide some additional information about the network design and what you would like to accomplish, and I will be happy to help in any way I can.
