You can also learn how to configure any Cisco ASA 5500 Firewall Here and also VPNs.įor more Cisco configuration examples and other related details about designing and implementing Cisco solutions: Cisco Tips and Tutorials. 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 above commands will accomplish the same task as the “global” and “nat” commands we had in versions prior to 8.3.ĭefault route towards the ISP (assume default gateway is 200.200.200.2)ĪSA5505(config)# route outside 0.0.0.0 0.0.0.0 200.200.200.2 1 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 device is the second model in the ASA series (ASA 5505. This version introduced several important configuration changes, especially on the NAT/PAT mechanism. Im offering you here a basic configuration tutorial for the Cisco ASA 5510 security appliance.

UPDATE for ASA Version 8.3 and later (including ASA versions 9.x)įrom March 2010, Cisco announced the new Cisco ASA software version 8.3.

Default Speed and Duplex By default, the speed and duplex are set to auto-negotiate. However, for traffic to pass through the VLAN, the switch port must also be enabled. Let’s see the basic configuration setup of the most important steps that you need to configure. Cisco ASA Series General Operations CLI Configuration Guide Chapter 11 Basic Interface Configuration (ASA 5505) Starting ASA 5505 Interface Configuration VLANsEnabled. By default, interface Ethernet0/0 is assigned to VLAN 2 and it’s the 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. That is, you can not configure the physical ports as Layer 3 ports, rather you have to create interface VLANs and assign the Layer 2 interfaces in each VLAN. 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. 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.
Moreover, the performance of the ASA 5505 appliance supports 150Mbps firewall throughput and 4000 firewall connections per second, which is more than enough for small networks. In this article, I will explain the basic Cisco ASA 5505 configuration for connecting a small network to the Internet (here the complete guides). The Adaptive Security technology of the ASA firewalls offers solid and reliable firewall protection, advanced application-aware security, denial of service attack protection and much more. 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). This article is still in draft so is yet not fully complete.The Cisco ASA 5505 Firewall is the smallest model in the new 5500 Cisco series of hardware appliances. Cisco ASA 5505 Basic Configuration Tutorial Step by Step Step1: Configure the internal interface vlan Step 2: Configure the external interface vlan (connected.So you need to configure you VLANs and then assign you ports to your VLANs.
The main difference between the other ASAs is that with the 5505 you have 10 ports which are not assigned to their own bridge groups. Below is an example of a basic configuration for an ASA 5505 Firewall.
