Install TFTP client on the machine is on the same network as of ASA Ethernet 0/1 – inside network. Of course there are much more configuration details that you need to implement in order to enhance the security and functionality of your appliance, such as Access Control Lists, Static NAT, DHCP, DMZ zones, authentication etc. The above steps are the absolutely necessary steps you need to configure for making the appliance operational. The PAT configuration below is for ASA 8.3 and later: NAT (static and dynamic) and PAT are configured under network objects. The “global” command is no longer supported. This version introduced several important configuration changes, especially on the NAT/PAT mechanism.

Step 5: Configure PAT on the outside interfaceĪSA5505(config)# global (outside) 1 interfaceĪSA5505(config)# nat (inside) 1 0.0.0.0 0.0.0.0įrom March 2010, Cisco announced the new Cisco ASA software version 8.3. Notice from the diagram that port Ethernet0/0 connects to the Internet and ports Ethernet0/1 to 7 connect to internal hosts (PC computers etc). The difference of the 5505 model from the bigger ASA models is that it has an 8-port 10/100 switch which acts as Layer 2 only.īy default, interface Ethernet0/0 is assigned to VLAN 2 and its outside interface (the one which connects to the Internet), and the other 7 interfaces (Ethernet0/1 to 0/7) are assigned by default to VLAN 1 and are used for connecting to the internal network. We will use Port Address Translation (PAT) to translate our internal IP addresses to the public address of the outside interface. We assume that our ISP has assigned us a static public IP address (e.g 200.200.200.1 as an example) and that our internal network range is 192.168.1.0/24. Although this model is suitable for small businesses, branch offices or even home use, its firewall security capabilities are the same as the biggest models (5510, 5520, 5540 etc).

The Cisco ASA 5505 Firewall is the smallest model in the new 5500 Cisco series of hardware appliances. Just as the commands in the ASA, the catalyst will show you now the number of Port Channel, port channel status and the physical Interfaces which are applied to this Port Channel group. Port state = Port-channel Ag-Inuse Protocol = LACP Logical slot/port = 5/1 Number of ports = 4 OK, first of all you have the configure the Port Channel on the Catalyst it is very simple something like that:Īge of the Port-channel = 761d:02h:50m:21s Here you can see the Port Channel configuration on an ASA 5540 and a Catalyst 2960. The Port Channel’s configuration is not really tricky but it is a little bit complex and it will be best if you keep the history of what you have changed to not lose overview of what and why you actually configured. If you run the Port Channel on the ASA then you are permitted to make up to 200 VLANs. The ASA distributes the traffics to all Interfaces, which means you have the functioning Load balancing, furthermore if you lost one or two Interface the whole traffics will be distribute to the Interfaces which are available. The benefit of Ether Channel or Port Channel is that you are able to configure redundancy and load balancing in the same time all four ASA Interfaces will be bundle to a link in the Layer 2 then you assign all VLANs directly to the Port Channel and so they applied to all Interfaces of ASA.

This was a standard solution to this problem, however since ASA version 8.4.2 you are able to use Ether Channel to solve this problem. To overcome this limitation you can configure some VLANs and trunk them to an Interfaces. Generally Cisco ASA has one Management interface and four Gigabit Interfaces, but in modern systems and scalable Infrastructures you will need more than four Interfaces.
