VLAN 2 derives its IP address using DHCP (from the ISP).

Here is also a new article I’ve written for a basic and advanced Configuration Tutorial for the new ASA 5506-X model. 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.ĭownload the best configuration tutorial for any Cisco ASA 5500 Firewall model HERE. 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.

The diagram below illustrates the network topology for the configuration setup that we will describe. Let’s see the basic configuration setup of the most important steps that you need to configure.

Static (inside,outside) 10.4.4.10 10.3.3.20 netmask 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.īy default, interface Ethernet0/0 is assigned to VLAN 2 and its 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.

I posted the configuration below, Could you please help me to solve this problem and make the pinging work between two hosts?Įnable password K2T/yDv1cYSJKgZq encrypted I already configured the NAT and I used pinging to make sure that my NAT configuration between two hosts works but unfortunately, it is still not working "I mean sending traffic from host A to host B and reverse". I'm using cisco ASA 5505 and I'm trying to configure nating between two hosts.
