I'm running a Cradlepoint CBA750B with IP Passthrough configured, connected to an R6700 with DD-WRT. I'd like the R6700 to handle most if not all traffic/DNS/DHCP, etc.
When connected/configured this way, i cannot access the GUI of the Cradlepoint. Cradlepoint IP: 192.168.0.1, R6700 IP: 192.168.0.2.
Is there a NAT or IP Tables command that will allow me access to the Cradlepoint GUI without screwing anything up?

If your cradlepoint is in passthrough mode then your R6700 should get the public IP address and not 192.168.0.2. In passthorugh mode your R6700 has to do all the work (DNS/DHCP etc) otherwise you would not have internet.
I am using a cable modem which is also in passthrough mode and I can reach my cable mode's interface without anything altered on my firewall.
(it is tricky to find the IP address of the cable modem as this is set up by the cable company, you therefore have to use tracert and IPscan) _________________ Routers:Netgear R7000, R6400v1, R6400v2, EA6900 (XvortexCFE), E2000, E1200v1, WRT54GS v1.

Yes, the R6700's WAN is getting the public IP for sure. The R6700 is still accessible on local LAN via 192.168.0.2. But the Cradlepoint is inaccessible on 192.168.0.1. I will give tracert/IPscan a shot when i get home, thanks.
