I would like to intercept all http and https traffic at the external interface on an ASA 5510 and forward it to a single server on the internal interface. I thought I could do this with static entries, but I seem to be able to only do 1 entry per server.
Can somebody tell me if this is possible, and if so, how?
No, you can't forward all HTTP or HTTPS traffic from external interface towards 1 single server. ASA supports URL filtering with N2H2 or Websense. ASA also supports WCCP, however, only if the WCCP server is in the same subnet as the traffic to be inspected.
I have about 6 URLs that I want to intercept and pass to a single page temporarily. I think I'm just going to create 6 web servers on an IIS server, each listening on a different port but pointing to the same index.html. Then I'll do static mappings from the public addresses to the single private address with port translating.
Kind of cumbersome, but it appears to be a workable solution.
