I have some query regarding firewalling and GRE tunnel traffic.The quieries are like this
1) Will I be able to inspect the traffic that is encapsulated on a GRE tunnel by putting a firewall (PIX or ASA) on the path of the GRE tunnel traffic.
2) If not , can i originate (or) create GRE tunnels on ASA firewalls.
3)If i use a IOS-Firewall router and if my GRE tunnel is starting on the same, will my traffic towards the GRE tunnel be inspected by the IOS FW.
Any help on these queries is appreciated
