Hi All,

We have recently purchased Cisco ASA 5510 and we need to configure it with basic configuration. We can access the ASDM and the device configuration throught it.

What we need is:

- Configure Internal and External Interfaces
- Allow all access from Internal to External
- Allow only port 1725 from External to Internal

Please advice with detailed steps and clear explanation.

    Accepted Solution

    The simple way is to just use the initial setup wizard. This will setup your interfaces and routing.
    All access from inside to outside is allowed by default.
    You have to tell us what internal IP scheme you are using (default is 192.168.1.x), and what specific IP address on the inside is supposed to be accessible from the outside using port 1725, and is 1725 TCP or UDP?

    Basic steps for that are:
    1) setup static PAT port translation. For this example, the host is and your interfaces are actually named "inside" and "outside" (use Internal,External if that is what you named the interfaces):
      static (inside,outside) tcp interface 1725 1725 netmask

    2) create an access-list to allow inbound to port 1725
     access-list outside_access_in permit tcp any interface outside eq 1725

    3) apply the access-list to the interface
     access-group outside_access_in in interface outside
