Cloudflare WARP on MacOS not setting routes correctly

What is the issue you’re encountering

Not all the networks listed in WARP client split tunnel is pushed to the MacOS system routes, so the system doesn’t know how to reach that destination

What steps have you taken to resolve the issue?

sudo route add -net 10.30.0.0/24 -interface utun0

This fixes, but it is a workaround

What are the steps to reproduce the issue?

I configured Zero Trust on my tenant with Cloudflare WARP client and network locations. The configuration from location home is in split tunnel in include IP mode. When I start the Cloudflare WARP client from my Mac I can reach all the networks in my list, except one (10.30.0.0/24). The network is correctly in the split tunnel list of the client but is not pushed to the MacOS system routes, so the system doesn’t know how to reach that destination. If I try from the warp client on my iPhone, with the same profile and from my home network, everything is working correctly.

I attached two screenshoots:

  1. the routes sent into the WARP client from Cloudflare
  2. the actual routing table from MacOS

I’m using the last version of WARP: 2024.11.309.0
MacOS is also on the latest version: 15.1.1

Anyone can help?
Many thanks

Tried also with the new MacOS release and WARP Beta client, nothing changed. Someone from the support can please help?
