I have looked through a lot of these posts on the Cisco ASA5505 as well as gone online. I am looking for some straight forward step by step instructions to complete the following tasks.
I know how to get it functioning with an inside and outside interface so that's great!
I need some step by step for the following tasks
Configuring the firewall. There will be two servers attached to the inside interface: one is a web server so ports 80, 25, etc... The other is the DC so all standard ports for that need to be opened up. We also need RDP opened to both machines we use a non-standard port. I feel if I saw one example like for port 80 I could replicate that. Are there any other configs I should be aware of to secure the actually firewall or does it come setup pretty well out of the box?
Setup access to the appliance from our main office and my offsite lab. I could also RDP to the DC on the inside interface then connect if that was more secure.
Here is my current status. Right now it is just setup on my work machine for some testing. So the outside interface just goes to the office network.
Result of the command: "show running-config"
