Opening ports for server applications like Ventrilo & Filezilla

I've installed XAMPP on one of my Vista computers, and intend to use it as a server.  The internal IP address of the server is A.B.C.D.  The internal IP address of the DIR-615 is A.B.C.E.  whatsmyip.com says that external address of the server is F.G.H.I (and so is everything else inside my network).  I have Filezilla listening on port 21.  I've turned Windows Firewall completely off on the server, and my ISP (Time Warner / Road Runner) says that they never block any port.

I tried going to the DIR-615 using Port Forwarding, and set ports 21 & 90 to forward to A.B.C.D, for both UDP & TCP, Allow All, Always.  That didn't work.

I tried going to the DIR-615 using Virtual Server.  I set a virtual server on port 21 to A.B.C.D, for both UDP & TCP, Allow All, Always.  It made me turn off Port Forwarding, and it wouldn't let me use both 21 & 90 on the same rule, so made two rules.  That didn't work either.

I tried setting A.B.C.D as a DMZ host.  That still didn't work.

I can ftp connect into A.B.C.D from one of the other computers in the network.  People outside the network can't connect to F.G.H.I.  I can't connect to F.G.H.I. from inside the network. The same is true of Apache (but ports 80, 81 & 443), Ventrilo (but ports 3784 & 6100) and MySQL (but port 3306).  I figure that FTP is the easiest to test, so I've been just trying to get that to work.

In FileZilla Server Options, I am bound to *, I have no filters, and my passive mode is set to "Retrieve external IP"

As far as I can tell, if I've ruled out anything inside my network (by connecting internally), and I've ruled out my ISP (they don't block), then it must be the router.  I think I've done port forwarding according to http://portforward.com/english/routers/port_forwarding/Dlink/DIR-615/FTP.htm, and it seems like it should be easy, but I've been trying forever and I can never get it to work.  I guess it's under "Advanced" for a reason (lol)

I have Port & Address Restricted for TCP on the firewall's NAT endpoint filtering
---
NAT Endpoint Filtering
UDP Endpoint Filtering:     Address Restricted 
TCP Endpoint Filtering:     Port And Address Restricted 
---
Does that have anything to do with it?

[FurryNutz]

could try setting both TCP and UDP to Endpoint Independent...

vwood,

have you find the solution to the problem? I am experiencing the same problem. Been trying to host a Sharepoint with no success.

I have rule out problem inside the internal network since I can access it from any PC from inside the network
