CM500 and CM600 public or private IP address assigned to router?
I would like to use my router's port forwarding capability to remotely access devices on my LAN such as IP cameras. I know that with an integrated modem/router this can be done - I have it working now...
If you are on Time-warner network, they should assign you a public IP and for e.g. if you connect CM500 Cable modem with a R7000 Router, thr router will get Public IP and you will not have double NAT situation.
I didnt know which ISP you had service with. some ISPs in asia provide private IPs to the users and it will create double NAT situation.
I have not seen any ISP so far in US providing Private IPs but I have only worked with Comcasts and Time Warners. Not sure of smaller players.
Thanks for the response vkdelta.
My ISP is Time Warner. I am sure they assign a public IP. Today I use a modem/router combo and the config/status pages show a public IP address is assigned.
So based on your resoponse that a modem-only device will act as a bridge, I am pretty sure that that getting rid of my modem/router combo and moving to a separate modem and router will result in the router being assigned the public IP and port forwarding working.
You mentioned double NAT is tricky, I understand that, but I don't see that a double NAT would happen -- does the modem perform a NAT function? I assume that it doesn't.
