I have an idea:
For a one-to-one floating IP, the gateway's processing may not need to care
about the session, let's say we do this:
When the client accesses the VM through an external IP, only a simple
stateless DNAT is needed, and a simple stateless SNAT is required for the
response.
When a VM accesses a public network, only a simple stateless SNAT is
required at the gateway exit, and a simple stateless DNAT is required for the
response.For many-to-one SNATs and LBs with port, stateful processing is also required. I want to ask everyone for suggestion. Is there any problem with this idea? Thank you!
