VLAN Tagged and Untagged traffic…
-
I know this question has been brought up numerous time and the answer has always been "don't mix tagged and untagged traffic"…in my curiousity and naiveness I would like to know why?
I have this setup and have some strange behaviour, I am wondering whether this is due to the above issue, therefore I would greatly appreciate some advice :)
I hope this makes sense...

Public Internet --- WAN(em0) --- LAN(em1) ------------------->
| |
| | --- VLAN10(em1) ------> [Switch] –- [Wireless Network (layer2 bridged AP's)] –--> Wireless AP's = No VLAN
| Clients with NAT'd IP's = VLAN10
(bridge) ------------- VLAN20(em1) ------> Clients with Public IP's = VLAN20Basically, we have three segmented 'networks'
- No VLAN (untagged) is our management network so we can access all the network infrastructure i.e. Wireless AP's and Switches.
- VLAN10 for clients who ONLY require a NAT'd local IP
- VLAN20 for clients who require a public IP which we can bridge with WAN
The tagging for clients is done on the wireless receivers or switches behind them.
I would like to know if there is an issue with the above method or whether there is a more efficient way of setting this up.
If I get the setup working I'll be more than willing to write a tutorial to help others!
