    Verizon is activating a line for us today they call a “10 meg” or a “LAN”.
    They said the only requirement is a regular fastethernet interface.
    Instead of using the Cisco 1841 we currently use (T1), i thought of using a clean factory default ASA 5505.

    1. Will this idea of using an ASA and skipping the Router alltogether work?
    2. never worked with an ASA before, what other points do i need in order to make the test work?

    by test i mean getting an Internet access by connecting an internal LAN switch to one of the ASA ports and having a PC get online access.
    once this test works, i will obvisouly need to recreate the various NATs and CALs i currently have on the 1841.

    any advice would be appreciated.

    this is what Verizon provided:
