    When combining dynamic and static NAT for Inside-to-Outside
    translations, are the Static NAT entries given priority over the
    Dynamic ? Is there and order of preference ?

    In other words: If I have 4 Static 1:1 translations defined, must I
    have matching explicit deny commands in my Dynamic source-list ACLs to
    prevent my statics from being dynamically NATed first ? Or will the
    Static entries take precedence ?

    From experience, the 1:1 statics take precedence, when they apply. Test
    it for your IOS version, tho.

    yes - i did some testing (with a 12.2 version) and it does appear that
    statics take precedence. Damn if I can find an answer anywhere on CCO
