I am trying to configure the dchub client dc++ to work behind isa server, but no luck so far. It used ports 411-412 tcp+udp. I have created packet filters for ports 411-412 tcp+udp (4 filters) and published rule to forward 411-412 tcp+udp (2 publishing rules using 2 protocol defs, 1 each for 411 tcp+udp and 412 tcp+udp). But I still cant use dc++ (I keep on getting connection timed out error). Can someone please guide me in this?

Thanks.

Hi Khurram,

One thing to do is to watch the IP...log when you're testing your setup; it can be very informative.

Since you're trying to reach a server behind ISA, packet filters aren't going to help (and will actually hurt). Use Server publishing and custom protocol definitions.
Assuming the client uses dynamic source ports (typical), the protocol defs would look like this:

(for TCP protocols)
Name = "<ProtoName>"
Port number = <ProtoNumber>
Protocol Type = TCP
Direction = Inbound

(for UCP protocols)
Name = "<ProtoName>"
Port number = <ProtoNumber>
Protocol Type = UDP
Direction = "Receive-Send", if a response is expected from the server, otherwise just "Receive"

Also, the internal server must be a secureNAT client (default gateway = ISA internal IP).
