I need to place my Westall modem into Bridge mode so I can access my security cams from out side my network. I have a DynDNS account set up and going. I just need to change the modem to bridge mode. Every time I do this I lose all internet conntection. I am running a Netgear WNDR3400 router behind the modem. Anyone got any ideas? Do I need to call verizon with I do this?
