We currently have a Cisco switch and router with in our environment. The router does inter-VLAN routing for traffic coming from VLAN's (about 6) on switch; typically as in a ROAS setup. So the switch is L2 and router is L3. Looking for a away to place the Palo Firewall transparently in between with two interfaces (eth 1/1 and eth 1/2); in vwire mode between the switch and router; so Eth 1/1 to connect to router and eth 1/2 to switch. Due to setup at site, we couldn't change IP config on switch and router. Wondering, if this setup would work in vwire mode. If not vwire; any other mode of interface config would work?
