Configuring Cisco ASA 5510

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.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

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 192.168.1.100 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 192.168.1.100 1725 netmask 255.255.255.255

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

Done.
