Asymmetric routing with pfsense and L3 switch

@kevindd992002 no but its another common bad setup see around here.. Users think they can create 2 networks say 192.168.0/24 and 192.168.1/24 on 2 interfaces and then just plug them into the same dumb switch..
and they wonder why dhcp isn't working how they want.
Or they will create 192.168.0/24 on the interface, and then wonder why they can't just run 192.168.1.1/24 as a vip and setup devices with static..
Technically you can get that sort of setup to work - but its not a good idea.. You might need to do such a thing while you transition from one IP range to another, etc. Or maybe someone put some device on the network with the wrong IP and you need to be able to get to it so you temp setup that wrong network to run on your current network, etc.
Another bad choice see all the time around here is setting up a bridge.. Can it work - sure ok.. But why, if what you want is a switch port, the correct solution is to actually use a switch ;)
Are there scenarios when a bridge is the answer - yeah sure.. But because there is some port on your device you feel is not being used, so you will think you turn it into a switch port by creating a bridge is not one of them ;)
There is no scenario I can think (at least off the top of my head) of where I would setup on purpose asymmetrical, and think well thats done ;) Let me go blog/post about how cool of setup I have - hehehe Its amazing he didn't put that nonsense on on some youtube video hahah, so other users can setup their network half assed..
I didn't read the whole thread - it was what like 400 some pages? WTF??? Was he going over how you could get something to work while they correct it? Or was he promoting that as a proper setup??
Lol, you would think they have some basic idea of how subnet works since they are using pfsense. Two networks in the same switch/VLAN is messed up.
For bridging, I completely agree on that. That's why for AP's that come usually with two ports, I tend to ask if that extra port is bridged with the main uplink port or what. It's almost always a passthrough which for me in the same as bridged. There's just some that make both ports connected to an internal switch.
That thread is one of the longest threads in that forum. It's a support forum for Brocade switches as they're one of the cheapest used enterprise switches you can get in ebay. The OP is pretty good and have been helping a lot of people with his knowledge about these switches. Not sure how that guy came about his post about his network setup but I just happened to also stumble upon his post because it was linked in another thread when I was trying to look for a workaround to the dhcp dns registration issue.

Hahaha - dude I ask myself that about many of the posts here, hahah.. Hey I get it, everyone starts somewhere, but I do wonder..
So was the post a hey, I wouldn't suggest you do this sort of post.. But this is "how" you could get it work..

@kevindd992002
If you have the VLANs defined on Pfsense then L2 traffic is going to flow across the trunk to Pfsense to route. The L3 switch is not going to route. -

Ahaha, I know what yoy're saying.
Yeah. From the look of it, he was mostly just sharing what he had done and it's not like he was trying to make people do the same.

@coxhaus right, I know that?
