v0.11.0-rc.1 network is not working on GKE

[EladDolev]

What happened:

the network isn’t working
I can’t reach pods behind services in offloaded namespace
neither remote->local or local->remote works
I see nothing in the logs

How to reproduce it (as minimally and precisely as possible):

1. install using Helm on local cluster running GKE 1.29 with COS and Dataplane V1
2. install using Helm on remote cluster running GKE 1.29 with COS and Dataplane V2
3. follow instructions to set up the network -> connections.networking.liqo.io shows Connected status
4. peer out of band
5. offload a namespace
6. offloading works, network isn't

Anything else we need to know?:

Environment:

• Liqo version: v0.11.0-rc.1
• Liqoctl version: v0.11.0-rc.1
• Kubernetes version (use kubectl version): v1.29.4-gke.1447000
• Cloud provider or hardware configuration: GKE with COS
• Node image: v1.29.4-gke.1447000
• Network plugin and version: Dataplane V2 is running Cilium
• Install tools: Helm
