it seems to loss internet connection only for destinations that needs to be routed through the VPN.

for instance, when i set up a WireGuard peer with AllowIPs = 1.1.1.1/32 on the Mac, then:

• ping 1.1.1.1 from the host - works
• ping 1.0.0.1 from the host - works
• ping 1.1.1.1 from the container - 100% lost
• ping 1.0.0.1 from the container - works
