This object controls whether the unit is in Bridge mode , Router mode or router mode with MTA as WAN IP. By default this has the value 1 for Router mode. In this mode, for eMTA router, like BVW-3653, the MTA IP and Router IP are separated. In Bridge mode, the DHCP server settings are not valid and the GwMgmtDhcpEnable will always read false. The CM would behave as a bridge CM only. In MTAasWAN mode, the eMTA router, like BVW-3653, would get the MTA IP for voice and use the same MTA IP for NAT purpose. To activate a change in this setting would cause a reboot of the unit.
