In the Layer 3 switch, I'll go ahead and configure the EIGRP process: Jumping into it, I'm going to start with the basic interface, IP, domain name and NAT configuration: This post isn't much of a deep dive but more informational in the even someone is building a lab similar to mine. This entry was posted in Tech Support, Uncategorized on Jby curreri.I have an ASA 5506 running in my lab and I wanted to establish the basic configuration for it first before I jump into the TrustSec configuration. Luckily, if you are having that trouble, I posted my solution here! I used these directions to set up my NAT, but found that my NAT’ed addresses were not able to access network resources outside of the firewall. If not, you may still want to add the new internal subnet so that other servers behind the firewall can have access too.
Configure cisco asa 5505 software#
If you were managing which subnets have access on the server’s software firewall, instead of doubling up your efforts you may choose to change the option to “Any computer” and let the Cisco ASA 5505 restrict by subnet.
Configure cisco asa 5505 update#
Lastly, don’t forget to update the exceptions in the server’s software firewall!
So, to use our internal IP address as a server, we need to open the firewall to allow traffic to come to this device. Now all packets which are allowed through the firewall and are addressed to the outside IP address we just named will be delivered to the internal IP address.
Use the ASDM software to log into your device.I’m going to go through the steps I went through to set up NAT and port forwarding using the ASDM software. This is all very easy to do on consumer grade hardware, but it’s difficult to do on the ASA5505 using the Cisco ASDM. The decision on what to allow through is based on what port the traffic is coming in on. Of course, because it’s a firewall, we need to tell the ASA5055 what traffic to allow through the firewall to the inside address. It means that we can have a public IP outside the Cisco Firewall, and it will route traffic inside to the internal address we select. What is NAT? It stands for Network Address Translation.
