Help with VLAN

Asked by moruda in Network Switches & Hubs, Network Design & Methodology, Miscellaneous Networking

Tags: VLAN

We need some help with this VLAN config.
We have 2 separate WAN connections -- A & B
Each plugged into the switch
There are 2 (redundant) firewalls plugged into the switch
Each firewall only has 2 (TWO) Nics- 1 for WAN and 1 for LAN

Here's a quick table of the Switch Ports
WAN A (PVID 10) Port1
WAN B (PVID 20) Port2
Firewall 1 WAN -  Port 3
Firewall 2 WAN -  Port 4


The firewalls will use VLANs to communicate with the 2 WANs through 1 NIC
We're confused about the TAGGING
Do we use TAG or UNTAG for the WAN links (Port 1 & 2) ?
And do we TAG or UNTAG for the firewall WAN ports 3 & 4?

THANKS!
