The ASA functions as a bidirectional tunnel endpoint.

Manage data transfer inbound and outbound as a tunnel endpoint or router.

ISAKMP and IPsec accomplish the following: The ASA uses the ISAKMP and IPsec tunneling standards to build and manage tunnels. Each secure connection is called a tunnel. Tunneling makes it possible to use a public TCP/IP network, such as the Internet, to create secure connections between remote users and a private corporate network. A site-to-site VPN is a Virtual Private Network that allow us to tunnel through the internet creating a private network connection been our two sites. Second we can use the Internet that we already have access to and employ a VPN. First we can purchases a dedicated line between the two sites but this is very costly. Additionally the show commands are limited and there is no debug command, this limits the ability to troubleshoot issues.īefore we begin our lab we need to get a better understanding of site-to site VPNs, and why do we need them? If we have two sites that are geography separated and we need to communicate between them we have two choices. The Nat command is limited to dynamic and static which does not allow the user to separate VPN traffic from the Nat process. Second the command set is limited there is no IP protocol available within the access-list command only TCP, UDP and ICMP.

First there is only a basic license available, this limits the DMZ capability. The functionality of the ASA 5505 is limited in the above version of Packet Tracer due to two factors. The inclusion of the ASA 5505 in the latest version 6.1.1 of Cisco’s Packet Tracer has allowed students studding for Cisco certification to model networks employing basic security using the ASA. The ability to configure and troubleshoot a Site-To-Site VPN using the Cisco ASA security appliance has become an essential part of a network engineer’s job as many networks today encompass multiple sites. Specify the configuring and troubleshooting of the ASA Site-To-Site VPN capability. We'll show an example below for a TFTP server.This Packet Tracer lab has been provided to help you gain a better understanding of Cisco ASA security appliance.

It's no secret that Wireshark is far more user-friendly than any kind of command-line analysis, so how could you do this? Simply set up a TFTP/SCP server or plug in a USB and move the captured file using the standard Cisco copy command. Let's now imagine you want to move the captured PCAP data to a desktop for detailed analysis.

How to save a packet capture for Wireshark Result in an excessive amount of non-displayed packets Warning: using this option with a slow console connection may We'll assign the interface a security level of 100 to ensure the firewall doesn't block any traffic incoming from the PC.Ĭiscoasa# capture pc-traffic-ssh interface INSIDE real-time Let's begin the setup by configuring an interface on the ASA which will connect directly to our PC.

Is the issue related to a firewall policy? Does it exist between the nodes or on one of the nodes themselves? Is the problem existent in one direction or both? Setting up our lab on GNS3įor today's example, we'll set up a Cisco ASAv firewall with a direct connection to a PC on GNS3. If the routing looks good but the nodes are still unable to reach each other, it might be time to perform a packet capture - this will allow the user to isolate the location of the issue. Step one would usually involve checking the routing table to ensure an entry exists for both nodes. The most frequent use case for a packet-capture is to debug a connectivity issue between two nodes.

Countless times during my career I've been able to diagnose network issues with this technique. Having the skill to capture traffic within a network is essential for any ambitious network engineer.
