The Solution Rating System

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.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Will this Cisco ASA5505 Config do what I need? (First time programming Cisco ASA)

Zones: Networking Hardware Firewalls, Cisco PIX Firewall
Tags: cisco, asa, asa 5505
I'm trying to setup a Cisco ASA 5505 for the first time. I'm trying to setup a very basic configuration, just to have it drop in the place of the Linksys router I have now. Essentially what I have now is a router that is a DHCP server, has an inside address of 192.168.1.1, and an outside address of x.x.67.57, subnet mask of 255.255.255.252, and gateway of x.x.67.58. It passes traffic on ports 80, 443, and 9100 to a device with an address of 192.168.1.40. Thats it! Does the configuration I have below mimic that behavior on my ASA 5505?

hi!
your vlan 2 - is set with dhcp, as for your description you want to be is static x.x.67.57/30

static nat records also should be added according to desired services:
static (inside,inside) tcp ST21VCPrinter 9100 ST21PublicIP 9100 netmask 255.255.255.255
static (inside,inside) tcp ST21VCPrinter 80 ST21PublicIP 80 netmask 255.255.255.255
static (inside,inside) tcp ST21VCPrinter 443 ST21PublicIP 443 netmask 255.255.255.255

i suppose you also need this:
access-list inside_access_out permit any any any
access-group inside_access_out in interface inside

> access-list outside_access_in extended permit tcp any object-group VCPrintSrv host ST21PublicIP object-group VCPrintSrv
This is incorrect as you are specifying the object-group for the source port. It should be :-
access-list outside_access_in extended permit tcp any host ST21PublicIP object-group VCPrintSrv

The previous poster is correct about the IP address on vlan2 but they make a mistake with the static commands. They should be :-
static (inside,outside) tcp ST21PublicIP 9100 ST21VCPrinter 9100 netmask 255.255.255.255
static (inside,outside) tcp ST21PublicIP 80 ST21VCPrinter 80 netmask 255.255.255.255
static (inside,outside) tcp ST21PublicIP 443 ST21VCPrinter 443 netmask 255.255.255.255

You dont need the access-list and access-group comands the previous poster mentioned. All traffic outbound is permitted by default.
