Hello Guys, I just change my ISP and get new LTE Modem ZTE WF830. When trying to connect turris to modem in bridge mode i’m getting DHCP error.

Connection in router mode does work but I would like to prevent having tripple NAT. I tried to reboot modem and turris many times but without luck. Any help is more than welcome

Hi,

and when you connect your PC to the modem (in bridge mode) - what happens?
as from these messages I would assume that the problem is with settings/dhcp or so on modem side.

Hi Mike,
once i connect modem to my PC it get assigned ISP’s IP, so it is working as it should.

And what IP your PC gets? (and mask and GW)
