Warp is forwarding my public IP as a 172.16.x.x

When activating Cloudflare WARP on my iPhone it is breaking my firewall rule that only allows traffic originating from the UK. My IP is showing up as a 172.16.x.x address in the firewall logs, in the past Cloudflare would forward my ISP’s IP to these logs.

Additionally if I activate WARP and browse to https://www.whatismyip.com (they use Cloudflare) it shows my public IP as 172.16.x.x when it should be forwarding my ISP’s IP.

If you think about VPN when you are using WARP, then it makes much more sense.

Because WARP is basically a type of VPN.

Sorry I’m not sure you understood my post. I understand that WARP is a VPN. Cloudflare is supposed to forward my real public IP to the destination (if the destination is on Cloudflare’s network) however this is not happening, instead it is forwarding a private IP address.

Ah, I just noticed that (172.16.x.x). In that case you might need to contact Cloudflare support and see why is this happening.

To contact Cloudflare Customer Support, login & go to https://dash.cloudflare.com/?account=support and select get more help. If you receive an automatic response that does not help resolve your issue, reply and indicate that you still require assistance.

Please share your ticket number here so that someone can track it.

I think this is a technical bug with WARP + http3, i’ve also observed it happening on other sites
