USG110 behind FreeBox modem
For many years, we have used a Zywall 5 with its multiple LAN outputs behind a FreeBox (Illiad) modem in France. We need to use this modem to benefit from the ISP (Free.fr) VOIP phone facility.
I would like to replace the outmoded ZyWall 5 with a USG110, but as yet not clear how to obtain the 'bridge' function.
Could someone advise me, or direct me to a guide, please.
