Enable Port Forwarding on Router

NAT

I am making an assumption that you are doing nat overload. If this is
the case, then you would simply add

ip nat inside source static udp 192.168.1.1 43398 65.65.65.65 43398

in the above example, 192.168.1.1 is the inside address of the device
you want to port forwarded to and 65.65.65.65 is a public ip address
that you have available (it could even be the ip address of the outside
interface.

ACCESS LIST

To open Remote Desktop Connection port 3389. You need an access list on the router.

access-list 101 permit ip 199.99.99.99 0.0.0.0 192.168.1.2 0.0.0.0 eq 3389
access-list 101 deny ip 199.99.99.99 0.0.0.0 192.168.1.0 0.0.0.255
access-list 101 permit any any

Change the 199 address to your public IP and the 192 to your LAN IP on the first listing. Leave the rest alone.

If you want to allow the port 43398 to be send out

You can use extended access list and implement it on the incomming and outgoing interface of your router

access-list 101 permit udp 192.168.1.1 eq 43398 65.65.65.65 43398
access-list 101 permit udp 65.65.65.65 eq 43398 192.168.1.1 43398


for both direction as router needs access to be defined for both direction.


Cisco Networkers 2009 – Firewall Design and Deployment

Cisco Networkers 2009 - Firewall Design and Deployment | 590 MB

This session addresses Cisco firewalls and how they are used to enforce security policy around the network. It includes best practices as part of a case study that illustrates these various techniques in practice and options on how they can be implemented.

Common design scenarios are covered for both the ASA firewall appliance and the Cisco Firewall Services Module, including virtualization and transparent (Layer 2) mode. Pros and cons of each design are discussed in depth. Participants should have a working knowledge of TCP/IP and understand general networking and packet flow. This session focuses on the Cisco ASA Adaptive Security Appliance and Firewall Services Module and does not cover any Cisco IOS based firewall solutions.

Hacking Exposed Cisco Networks
December 2005 | English | ISBN : 0072259175 / 9780072259179 | 400 Pages | Paperback | 9.8 MB

Overview

Here is the first book to focus solely on Cisco network hacking, security auditing, and defense issues. Using the proven Hacking Exposed methodology, this book shows you how to locate and patch system vulnerabilities by looking at your Cisco network through the eyes of a hacker. The book covers device-specific and network-centered attacks and defenses and offers real-world case studies.

Biographical note

Dr. Andrew A. Vladimirov, CCNP, CCDP, CISSP, CWNA, TIA Linux+, is a co-founder of Arhont Ltd., an international IT security consultancy.

Konstantin V. Gavrilenko, co-founder of Arhont Ltd., has extensive experience working with Cisco PIX firewalls and Cisco VPN concentrators.

Janis N. Vizulus is a researcher and programmer specializing in digital forensics and penetration testing.

Andrei A. Mikhailovsky, co-founder of Arhont Ltd., is an expert in network security and penetration testing

Back cover copy Implement bulletproof Cisco security the battle-tested Hacking Exposed way Defend against the sneakiest attacks by looking at your Cisco network and devices through the eyes of the intruder. Hacking Exposed Cisco Networks shows you, step-by-step, how hackers target exposedsystems, gain access, and pilfer compromised networks. All device-specific and network-centered security issues are covered alongside real-world examples, in-depth case studies, and detailed countermeasures. It's all here--from switch, router, firewall, wireless, and VPN vulnerabilities to Layer 2 man-in-the-middle, VLAN jumping, BGP, DoS, and DDoS attacks. You'll prevent tomorrow's catastrophe by learning how new flaws in Cisco-centered networks are discovered and abused by cyber-criminals. Plus, you'll get undocumented Cisco commands, security evaluation templates, and vital security tools.

Use the tried-and-true Hacking Exposed methodology to find, exploit, and plug security holes in Cisco devices and networks

Locate vulnerable Cisco networks using Google and BGP queries, wardialing, fuzzing, host fingerprinting, and portscanning

Abuse Cisco failover protocols, punch holes in firewalls, and break into VPN tunnels

Use blackbox testing to uncover data input validation errors, hidden backdoors, HTTP, and SNMP vulnerabilities

Gain network access using password and SNMP community guessing, Telnet session hijacking, and searching for open TFTP servers

Find out how IOS exploits are written and if a Cisco router can be used as an attack platform

Block determined DoS and DDoS attacks using Cisco proprietary safeguards, CAR, and NBAR

Prevent secret keys cracking, sneaky data link attacks, routing protocol exploits, and malicious physical access

Cisco AIO Tutorials LABS

Cisco AIO Tutorials LABS | 483.2MB

Most of them are in iso files format, Its not just a video tutorials, those are mostly. Labs, it means you open an html file inside that, and you will see 2 parts, one in flash and another in text. At each lesson you finished, you will get to challange flash where you have to practice things you have learned, its like working on real cisco device. You'll have the flash SSH shell, and you have to type in the cisco commands, and in case you make a mistake, you'll get wrong alerts and you can then either correct it or need to read and listen to the section again and see the correct answer by clicking the DEMO option, that will show you the entire solution. By the way, this is original cisco materials that you need to pay $$$$$$ for it, but for keen learners it is for freeee!!
