I have a webserver that that has a portmapping from the outside x.x.x.x port 80 to a dmz address y.y.y.y port 82. Works fine. I want to have the outside x.x.x.x port 80 mapped also to a dmz address v.v.v.v port 83 when x.x.x.x is taken down to display a slash page for temporary outages. I would only have one rule active at a time. Any way to do this? I disabled the real rule and tried to add the temp rule but the ASA will not let me.
