Hello People ,


We have a situation where in  a Site to Site IPSEC exists between Cisco ASA and PALO ALTO FW 


The LAN segment of the Network is behind Cisco ASA . Infact all of the VLANS  are in this LAN Segment which is Behind Cisco ASA .


The requirement is that Gateway for these VLANS will be the PALO ALTO FW


So i need to know if it is possible to have VPLS over GRE on Palo ALTO 


LAN( VLAN )>>>> Cisco ASA 5500Series>>>>>S2S IPSEC >>>>PANFW (Gateway for VLANS).


Can anyone help here ?

How do the broadcasts from the clients traverse the IPSEC tunnel? The ASA can use policy or route-based VPN but I don't think either will have a mechanism to allow broadcasts. Without that, the clients won't be able to find their gateways.

Why do the gateways need to be on the PAN?

Through GRE Tunnel . This is a requirement from client 

Where are the gateways now?

What's going to terminate the GRE tunnel on the client side? ASA doesn't support GRE. 

Sorry the other side is SRX and not ASA ,
