@awebster said in VLAN 0 and pfSense:
I doubt that you'll find any support for VLAN 0 in the SG200
The only difference I can see with VLAN 0 is sending it untagged to the default LAN. I don't imagine that would be hard to do. Beyond that, it should be handled the same as any other tagged frame. Again, I'll have to try it some time.
If you're serious about learning the ins and outs networking, get your hands on some used Cisco gear like 2960 series for L2, or 3750G for L3
I do have a Cisco 2600 router, which I used when I was working on my CCNA. Also, years ago, I worked for Adtran's Canadian distributor. I had plenty of access to networking gear then. 😉
