The ASA will allow users in DMZ2 to access the DNS server in DMZ1. We first simulate web browsing traffic initiated from a host on the internet with IP 10.1.1.200, trying to reach the web server on port 80. The following command sates: “Generate a fake packet and push it through to the ASA’s outside interface in the inbound direction.
Packet-tracer just assumes that the packet comes in on the outside interface and does cannot differentiate it as VPN traffic. What’s going to happen then is that the packet-tracer will show a drop on Phase 3 (ACL check). For this to work, the admin may need to temporarily add the Anyconnect traffic to be allowed on the the outside-in ACL. Solved: Packet Flow in Checkpoint Firewall - Check Point I am very confused with the packet flow of checkpoint firewall. I have seen in many places fw ctl chain is referred to understand the packet flow but I am not able to interpret it. Could someone please help me in understanding the packet flow in terms of. SAM. IP spoofing. Policy lookup. Dst NAT. route lookup. Src NAT. VPN… Site-to-site IPSec VPN - Packet Pushers The ASA will encapsulate traffic with this destination into the IPSec tunnel. Finally there is an eastbound default route for non-tunnelled traffic to reach any IPSec peers, remote management of the ASA and any other services. B-End (Remote Site) There is a default route on the B-End ASA sending everything via its westbound interface (outside).

If the packet flow matches an existing connection, then the access−control list (ACL) check is bypassed, and the packet is moved forward. If packet flow does not match an existing connection, then TCP state is verified. Packet Flow Sequence in PAN-OS - Palo Alto Networks
