Two things happening here, one is confusion. The machines (10.1.141.53, 10.1.178.197, 10.1.201.48) are all trying to connect to the firewall's external address not any outside source unless you didn't post the outside sources. Your eMule clients are trying to get out to the net. Did you list the external_ip as your gateway? If so that answers your question. If not then run a sniffer on your network to determine what traffic is being passed to and from those addresses to and from the firewall to the addresses, that would show you what exactly is happening INTERNALLY. If you suspect something fishy on the machines themselves, then I suggest using Process Explorer, and TCPView on the Windows machines to get an idea of what is doing what. http://www.sysinternals.com/ntw2k/freeware/procexp.shtml http://www.sysinternals.com/ntw2k/source/tcpview.shtml =+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ J.
