Best thing is to set a separate LAN for the BGW210 and a separate LAN for the other router. For example, I set my BGW210 to 192.168.3.254, with DHCP 192.168.3.1 - 192.168.3.253. On my other router, I left it set at 192.168.2.x. Use any LAN port on the BGW210 to connect to the WAN port on your other router.
But then that isn't IP Passthrough. I currently have that set-up and my own router is complaining about double NAT. AFAIK, if it were IP passthrough, the publicly routable WAN IP address that comes into the BGW210 would be passed through
to one's own router's WAN port so then it
would have the original WAN IP address, i.e., it would be as if the BGW210 weren't even there.
When I select IP Passthrough
, neither the Default Server Internal Address
nor the Passthrough Fixed MAC Address
fields are editable. If I change it to DHCPS-fixed
, then I can enter something into the Passthrough Fixed MAC Address
I did try this and it fubar'd my network. I couldn't even access the BGW210's web page any more, so I had to factory reset it.
Question: assuming this did work and the BGW210 were passing everything through to my router (which is 192.168.2.1) and network (192.168.2.x), then how can you access the BGW210's web page? If it's pass-through, then you'd think it wouldn't even have
an IP address any more.
