packet flow from VLAN Host to www - how often routing decision is made?

Sun May 14, 2023 5:21 pm

Hi there,
it has been a while
I'm reviewing my firewall rules and have some hiccups grasping all again.

I asked myself quite a basic question but my mind was filled with other things, so I would like to have a second opinion on it.
How often will a package flow through this before it hits www (or my ISP) if I have VLANs and Bridge
If I combine

it is only once, isn't it?

Simplified it is:
  1. From host to Interface on router (VLAN trunk / tagged port is the physical in)
  2. Then Decapsulation takes place
  3. Afterwards it goes to the Logical In Interface, the respective VLAN Interface
  4. Then, it is forwarded to the physical WAN interface where it leaves the router with any other processing on the router anymore
