I'm trying to put my modem in bridge mode so I can plug it into a separate router but I'm having some difficulties. To try to get the facts straight on the settings required I've plugged it straight into my laptop.
The modem-router is Zyxel P660R. I've tries to get all of the settings from the router when it's still running in routing mode, they are as follows:
ZyNOS Firmware Version: V3.40(ANZ.3) | 05/16/2007 WAN Information: DSL Mode: ADSL_G.dmt IP Address: 184.108.40.206 IP Subnet Mask: 255.255.255.255 Default Gateway: N/A VPI/VCI: 0/38 LAN Information: IP Address: 192.168.1.1 IP Subnet Mask: 255.255.255.0
The IP Address was specified manually (dhcp didn't seem to work). It seems really odd to me that the Default Gateway is not assigned..? It's obviously getting this from somewhere (dhcp?) as the internet works. In the config where the static ip is entered there is no option to enter the default gateway manually.
When I change the modem-router to bridge mode and try to obtain the setting over dhcp I end up with an ip address 192.168.0.34 which again seems odd, why is the modem handing out ip's? I was expecting my static ip (220.127.116.11). So rather than dhcp I could configure it myself, specify 18.104.22.168 as ip, but then what should I use as the subnet and default gateway - when the modem-router was in router mode it said N/A.
Do I just need to go to the isp and ask for the gateway and subnet?
