    Question

    * $alephe_tab/server_ip_allowed file has the following entries:

    W A 10.1.235.*
    W A 10.1.1.*
    W A *.*.*.*

    P A *.*.*.*
    P A *.*.*.*

    X A 192.168.6.*
    X A 192.168.3.*
    X A 192.168.2.*
    X A *.*.*.*

    We are concerned about the vulnerability of having the *.*.*.* entries and would like to remove them.
    If we do this, how do we determine what IP addresses we need to put into this allow file?

    Answer

    P" (PC Server):
    include all IP addresses of all PCs which need to access the servers, using the "*" wildcard as much as feasible
    include all Ex Libris Firewall addresses to allow support - see 'Ex Libris offices IP addresses' (KB 23827)

    "X" (X-Server)
    check all software running at your site, the only IP addresses for "X-Server" should be your own internal addresses

    "W" (WWW Server):
    to allow access for everyone, you need to keep
    "W A *.*.*.*
