Non-bridgeable modem

CarlosNaldinho

I had a perfectly functional UTM setup but I was required to change my modem to one that can not be put in bridge mode.

I've been at this for a few hours and I can't figure put how to setup the WAN interface now that the modem is handling the authentication with the ISP. 

Can someone tell me if this is possible and even better what settings I should be using?

    Right, so the uplink used to be DSL (PPPOE) when I was able to put the modem into bridge mode -- not that I can't put the modem into bridge mode I don't know what type I should be using.

    The menu gives me 7 choices -- 3G/UMTS, DSL (PPPOA/PPTP), DSL (PPPOE), Ethernet, Ethernet Bridge, Ethernet VLAN, and Modem (PPP).

    Of those, I can rule out four as obviously not what I want and it seems to me that I should want Ethernet but that doesn't work -- The interface remains down and the UTM actually becomes non-responsive and it takes quite a bit of just rebooting to eventually be able to get back into the configuration panel.

    Please show us an edit of your interface configuration of that ethernernet port on the Sophos.

    If you still have login credentials for DSL, then you would need to use the DSL PPPOE most likely.  The only thing that would be plugged into the modem would be the UTM, so that would be a LAN port (assuming DHCP is on your UTM).  Everything else should be behind the UTM. 

    Modem --->UTM--->Switch/hub ---> client devices/APs.
