What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

-i don't have modem
wan ip 188.26.208.1xx

I try what you said ...

Virtual Server is working Port Forward don't
I think is something wrong with my dir-655...

[FurryNutz]

If you don't have a modem then there could be a problem at there end in that they could not be opening up the ports or having an additional router thats causing a double NAT condition.

....I don't think so...
- With my old iptime router i can forward port range..
-with Dir-655 Virtual Server I can forward ports...
 What is the difference between Virtual Server and Port Forward ?

[FurryNutz]

The difference between Virtual Server and Port Forwarding is that Port forwarding merely opens the port up to the selected client or computer. Basically the computer has to be connected and listening on that port in order for it to work as any incoming connection to that port can still be pick up by any other client on the network if the port is not in use at the moment the connection comes in with the exception that is blocked or firewalled for them. If there is an incoming connection to that port that is forwarded and no client is listening for that port the router will just block or disregarded as it does not know what client to connect thee incoming connection. Torrent downloading uses a lot incoming connection to one port and so it can confuse the router. Virtual server opens up the port and fowards any incoming connections to that port to the client specified only. This means that no other client on the network has access to that port at all since it only accessible by the client specified, and thus the reason why it works better than port forwarding in terms of use for torrenting or any app that is listening on a specific port without sending out data until a connections is made. Basically the Router knows that all incoming connection to the specified port go to the specified client and so the router does not get confused.

The reason why these two option exist on the router at the same time is simple. If the Router just had Virtual Server option available, than as you add more port to a client the other clients will have less port available to them. The more ports you add the less ports are available for other clients. With Port forwarding this is not an issue as the port is still available as long as is not in use. It is recommended you try port forwarding first before trying Virtual Server since it will make the port specified useless to other clients on the network.

In fact I realized that is working ...
When I try to access the public ip from internal network, just ports forwarded  with Virtual Server are working , Port Forward ports are  open and can be accessed only from outside the network .... (or inside at LAN ip). ..
It's a loopback thing..

Thanks for help
