Possible approaches:

Multus CNI
- (-) external dependency
manually invoke CNI for the tunnel container
- (?) will network policies apply?
- (-) this might be problematic from the security perspective (highly elevated permissions would be required)
- (-) inelegant and hacky
~~pod per peer~~
- (-) doesn't scale

Challenges:

we need to ensure that peer CIDRs from NAT-free networks do not collide
