I see this topology below is possible:
Notice the Asymmetric Routing interface in use.
The two WAN-facing interfaces are both independent, and do not share a common virtual IP address
The two LAN facing interfaces share a common virtual IP address.
My question: Is it possible to modify this design, for the LAN facing interfaces to both be independent, without requiring a virtual IP address shared between them? Will this break the NAT HA design?
This is the design I need to am hoping to accomplish:
Notice the is LAN A and LAN B (no virtual IP on the LAN side)
