WAN IP and IP Passthrough & Old Router

Question asked by shinoamakusa on Jan 22, 2016

Today I have upgraded our old Motorola modem to a newer Cisco DPC3848V one. As I prefer to keep using our old WiFi router, we have setup IP Passthrough on the modem to our old router and disabled wifi on the Cisco modem.

 

Now, everything is fine with internet and such, but my old wifi router gets WAN IP as something like 192.168.0.13 (which is assigned by the modem and is not public ip)

 

Is there a way to pass public wan ip from modem to router so that I can access from outside my network using ddns and have access to vpn that I have setup on old router ?

If so, then would disabling dhcp server on modem and leaving it on the old router do the trick?

 

Thank you,

Oleg
