I purchased an 851 non-wireless router a few months ago. I have tried to configure it using SDM, CNA and CLI. I can connect and alter and upload new configurations without problems.
My issue is the configuration itself! I have gone through countless tutorials, how-to's, examined sample files, etc, and I cannot seem to get it working properly.
My setup is very simple: I have a linksys cable modem. I want to connect the 851 directly to this, and my computer to the 851. I need to be able to connect to the internet through this setup. I want to be able to plug other computers and a wireless router into the 851 at will, and have them connect to the internet as well. If I can get this far, then I will start putting ACL's in place to secure the thing to some extent.
This behavior has been 'default' in every other small router I have worked with, but not the 851.
I really am trying!
I am attaching my current config.
Thanks for any help you folks can offer.
