Anyone who could help with below question:
Setup:
- Single site Maestro R81.10 including latest JHF
- 3 external interfaces, each of them connected to another router
- 3 default routes are received via OSPF (equal cost).
- All antispoofing is enabled and is using the routing table information.
What happens for:
1) Outgoing connections?
Outgoing interface is determined using Weighted Fair Queueing. What will happen if the return packet enters on another interface? (Asymmetric routing) - As the antispoofing is configued correctly, will the flow be accepted and fully inspected?
2 Incoming connections?
We have no control about on which interface the traffic is entering. But will the reply packet use the same interface for replying (stickiness)? Or will it determine the external interface using the 'Weighted Fair Queueing' and thus potentially creating asymmetric routing?
Thanks!
