I have an Exchange server published through ISA on a static IP address allocated to a DSL RASPPPoE connection. When the connection drops (our ISP does that more often than I like) the ISA firewall detects that and a Server Publishing Failure entry is written to the event log. However, when the connection is reestablished (=redialled) no Server Publishing Recovery event occurs. This means all servers stay unreachable as ISA doesn't restablish the LISTEN on the published ports. If the ISA firewall service is restarted it works again. The Network configuration change event is happening in both cases (on connection dropped and on connection reestablished) which means that ISA does detect it. However, it does not reestablish the published servers on that IP. Is this a known "feature" or have I got possibly something wrong in my configuration or ...? Any help appreciated. Manuel
