you can share a switch & only utilise a single physical port per
firewall per side (1 for external, 1 for internal).
each WAN connection connects to a port on the same switch but each
port is in a different VLAN.
both those VLAN's are tagged on the port each firewalls physical
interface is connected to.
On the firewalls use vlan(4) interfaces to talk on each WAN connection.
Keywords: router on stick, trunk ports / tagged vlans.
You could resort to only tagging one VLAN & making the other VLAN
untagged per interface but it's better to have them both as tagged as
it's cleaner & makes it easier to move things round later.
