tbrig1 Posted June 2, 2020 Share Posted June 2, 2020 Hi! I'd like to use the Netduma behind another router as more of a L2 switch on the same subnet as my main network. I tried this with the latest DumaOS and original R1 firmware and was unsuccessful. Is it possible to use this configuration? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted June 2, 2020 Administrators Share Posted June 2, 2020 I don't think that will work, the R1 will be assigned an IP address and so any devices connected to the R1 will need an IP address from the R1. Link to comment Share on other sites More sharing options...
tbrig1 Posted June 2, 2020 Author Share Posted June 2, 2020 Okay, thanks for the response. If I am using it behind another router/firewall, is there any issue I should be concerned about with the double NAT? There was some mention of this in the UI but no info or tips on what to do if I experience issues with this config. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted June 2, 2020 Administrators Share Posted June 2, 2020 Yes, I would recommend you either put that router in modem/bridge mode or use the R1 WAN IP (found in Device Manager) in the DMZ of that router, you then won't have an issue with double NAT.
