With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

How to block internet port 80 on specific network computers - Cisco 871

Asked by jasonc74 in Network Routers, Miscellaneous Networking

Tags: Cisco 871 internet block

I have a network of about 20+ computers with the need to block port 80 traffic on about 5 of them. The 5 computers have static IP addresses in the 192.168.0.x subnet. I have attempted to create an access-list 150 to block 80 on 192.168.0.63 and apply it to Vlan1 but that doesnt seem to work. I dunno if im not applying the ACL in the right place or not.

The current router config runs:
NAT translation for internet access connected to Fe4
VPN Server with split tunneling for client users
VPN Point to Point connection to a remote site

Any help would be greatly appreciated!
