    Hello All,

    I have an SBS 2003 Premium R2 (without ISA installed) and a SoniWall Pro
    1260 (had a Linksys RV082 before). I am having some port forwarding issues
    but the current pressing issue is port 8016 for the ADT remote camera watch.
    Basically, after troubleshoot with SonicWall support and did a Packet Trace.
    It turns out that the firewall is sending port 8016 traffic to the right
    destination which is the ADT camera DVR but the the SBS server is the one
    responding instead and on random ports (sort of like intercepting the
    response that the ADT DVR is supposed to be sending back to the remote
    computer on WAN. On LAN it works fine. The following are the packet trace

    #: 1
    Time: 10/22/2008 09:39:47.768
    Content: TCP received on OPT [ACK] 60 bytes
    From: External.IP 64630 (00:03:1b:12:76:12)
    To: My.Firewall.IP 8016 (00:06:b6:3c:98:7b)

    #: 2
    Time: 10/22/2008 09:39:47.768
    Content: TCP sent on OPT [ACK] 566 bytes
    From: SBS.Server.IP 98765 (00:06:b6:3c:98:7b)
    To: External.IP 64630 (00:03:1b:12:76:12)

    I'm unsure why SBS is getting in the mix here as I have not personally
    configured anything on the SBS on port 8016, or does SBS use port 8016 for
    anything I am unaware of?

    Any ideas?

    I'm guessing you need to add some port exclusions

    Thanx for your response but that did not resolve the issue. Any other ideas?

  4. Did you put in a port exclusion for 8016 in that reg key?

    Yes, I did put in a port exclusion for port 8016 in;
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ReservedPorts and rebooted still no dice. Anything else I could be leaving out here?

  6. Only other thing I can think of is doing a netstat -ano and see if you
    can see if there is something listening there?
