I have a Technicolor TG589vn v2 in bridge mode, connected to a wireless router running DD WRT. Now the WAN IP address shown on DD WRT interface is different from my public IP which I believe was same before. DD WRT router is doing the authentication with connection type set to PPOE. WAN IP shown is 100.XX.XX.X. Can someone please explain what is going on and what is this WAN IP and where it coming from as Technicolor is in bridge mode with IP address set to 192.168.2.1.
Thanks

100.64.0.0/10 is the CG-NAT range.

I assume your provider is probably bigpipe or flip? That is why the public IP is different to the one shown on the wan interface of your router.

He changed to BigPipe so CG-NAT is the answer :)

Thanks. Well port forwarding is proving to be a challenge. Not working with my previous settings. Do I have to do anything in the Technicolor modem too?

Port fowarding doesn't work with CG-NAT. You will need to order a static IP for that.

It won't work with CG-NAT. You'll need to request a static IP from BigPipe but you'll also find services will work as expected still. You shouldn't need to get a static IP unless if you're hosting things yourself.

You don't have a public IP address when on CG-NAT, so you can't set up anything that requires incoming connections.

You need to ask BigPipe for a public IP address instead. I don't think they do this sperately from a static IP any more, so you need to request a static IP
