Here is a sample from the course that will train you on the Cisco CCNA Security Firewall and how to configure it with SDM.

Recently, I created a short video that shows you how to configure and use VLAN s on a Cisco IOS Router & Switch. It is a step-by-step 15 minute video. It was originally published over at SearchNetworking.com. A virtual LAN (VLAN) is a broadcast domain created by switches. VLANs are a convenient way to connect ports from different switches and different buildings onto the same network and broadcast domain, preventing the need for a complex system of subnets.
In this video, you will learn how to configure a VLAN in this step-by-step, automated, 15-minute demo. I am a CCIE Cisco networking expert and I will walk you through the steps you’ll need to configure your routers and switches, set up and assign the trunk ports, and perform the necessary tests to get traffic moving across your VLAN successfully. You can view the configuration commands I used in the video at the bottom of this page.
Oh – if you would like to see an EXCELLENT video training course that covers all aspects of VLAN configuration, switch configuration, and prepares you for the CCNP, please check out the Train Signal Cisco CCNP Training Video Series – 642-812 BCMSN

Recently, I created a short video that shows you how to secure your Cisco router using Access-control lists (ACL) in the Cisco IOS. It is a step-by-step ten-minute video. It was originally published over at SearchNetworking.com.
In this video, I walk you through the steps you’ll need to take to use Cisco IOS access control lists (ACLs) to define and filter traffic for better network security.
I recommend Train Signal Cisco CCNA Video Training!

Here is my network diagram (click on it to enlarge it):
Here is the actual ACL used in the video:
! SAMPLE ACL

!Notes-
!DNS resolution must be happening locally
!Default gateways must be configured on each side of the network
!If you were doing this between a LAN and the Internet, you would have NAT to
take into account
!Reflexive access-lists or firewall features can be used to improve on this

Recently, I reviewed Train Signal’s Video course covering the Cisco CCNA certification. Honestly, these Cisco training videos are the best I have seen. The instructor is Chris Bryant. He is a CCIE and has a knack for explaining the in’s and out’s of Cisco networking. Take a look at this video sample of this great CCNA training course so you can learn Cisco Routing & Switching from a Cisco Expert!
