Title: [Solved] Bridging weirdness
Post by: pablo on January 22, 2021, 11:50:50 PM
Hi,

I am trying to understand a particular behavior with my bridge set up that's causing me heartburn.  :D

Below is some ASCII art of my set up:

Interfaces
==========
o LAN   - ig0

o WANBr - ig1

o LAN2  - ig2
   |
   +---- V1010

o WAN   - bridge0
             |
             +  WANBr + V1010

Topology
========
VM -- V1010 -+
              |
              +-- [ GW ] -- WAN -- [ GW2 ] -- Internet
              |
   ...  LAN --+


If I ping the VM from any machine on the WAN, an ICMP reply is setn from [GW2]

If I ping the VM from [GW], the ping appears to go through [GW2] since it's a wireless connection.  The ping time is in ms versus sub-ms (what a local ping should be).

I cannot ping the VM from any machine on my LAN.  Using tcpdump, I never see a reply hit the LAN interface.

Any tips on how to proceed?   I'm going crazy!  :)

Thx!

During my tests I was using OPNSense in my VM.  I thought, hmm, perhaps I should try something else. 

I downloaded Puppy Linux (it's small) and voila, everything is working as I expected.

Thx!
