DIR-300 router and broadband ISP connection,is NAT possible?

I would contact your ISP for help with this one. It should work but you would want to check the LAN and WAN settings to make sure they work on the network since there have been changes.

YES IS POSSIBLE.ALSO UPDATE THE FIRMWARE.

If you need more help post back!
Thumbs and testimonial are welcome!

I assume you have connected your switch to any broadband router and then trying to access multiple systems at the sametime.
This is not possible if NAT (Network Address Translation) is not enabled on your broadband router.

On the Router check if you have UPnP enabled, if yes then Disabel it that should fix the NAT issue and then you need to open the port number 1723,3389. Once these ports are opened then you will be able to access it on the VPN and Remote Desktop Provided you have a WAN IP Address from your ISP. also check the Firmware of the router if its updated or not.

HI! I bliv u are having some issue setting up ur router.. I will be more than glad to assist u. . here are the steps u need to do:
1. press the reset button on the back of the router for 20sec..while pressing the reset button, unplug the power plug and after 2secs while pressing the reset button plug it back in and press for 30secs after that unplug the router for 15secs then plug it back in..once all the lights are solid and ok
2. connect the ethernet cable to port1 of the router and the other end to the lan port of your computer..
3. pull up ur browser then type at the url:192.168.1.1.or 192.168.0.1 or u can check the routers default gateway by right clicking the network icon on the lower right of your task bar and click on status and it will show the ip address of the computer, subnetmask and default gateway, the default gateway is the routers ip address, once u type in to the url, it will ask u the username and password, by default the username is admin and the password is 1234 or just leave it blank
4. it will show the setup page of the router. u can set the router on the specific internet setup that u have.
a. if ur isp is a cable company, normaly u need to do a mac clone on the router setup page by cloning the computer that is reg to the cable company, how to determine it. ex. the computer that is reg to the cable company is a desktop or laptop, if this computer is connected to the modem directly and u can access internet.
b. once u determined it u need to connect this computer directly to the router and do a mac clone and set ur internet settings to auto-dhcp..then save the settings and after that, unplug to the power of the modem and router, plug in 1st the power of the modem then once all lights lit, plug in the router, then once all lights lit, try to pull up a browser that ur computer is connected directly to the router.. ur cable connection shud be, cable from the modem will go to the WAN port of the router and connect ethernet cable on port1 going to the lan port of the computer..once u can access the internet, u can now access again the setup page of the router by typing at the url:192.168.1.1 and u can setup the wireless settings, u need to create a ssid or wireless name and a security..
5. If ur isp is a dsl normaly they give u a username and password to connect to the internet, ur settings on the router should be PPPoe
6. If ur isp gives u a static ip address settings, u need to set the router to isp setup.
a. how to check the isp of the isp given to u..
1. click on start
2. run
3. type cmd
4. it will show a dos prompt
5. from the dos prompt type ipconfig/all
6. it will list the ip address, subnet, default gateway, dns server
this settings should be type in to the settings on the router for static ip addressing..
7. Once your done on the internet setting, go to your wireless connection settings and you can create a wireless network name or ssid, set a security by selecting wep, wpa, wpa2.
8. once all is set. save the settings and to check if your laptop can access the wireless network that you did, turn on the wireless switch of your laptop, once its on, it will show the wireless network icon on the lower right of the taskbar, right click it and select on view available network, the network name that u did should list, just select it and connect and it will ask for the password, just type the password and connect, you should be connected to the wireless network and have internet access..
9. If you are going to hook up your desktop to the wireless connection, you need to install a wireless network adapter, install the driver and do the same thing as u did to the laptop, for the desktop no need of turning on the wireless switch, once you install the driver correctly, it will show a network icon..
if you have any query pls feel free to get in touch.. good luck

HI, Upgrade the firmware on the router and then forward ports on the router for the IP Address of your PS3.

Let me know if you need any further help.

you can put your ps3 in a dmz zone. if still does not work its not your router. u can keep your ps3 in dmz and get your router to open ports. u can call your router company. If still does not work its not your router more than likely. It might be your modem. i have at&t and that was my issue. i went to dmz on modem and allowed it to pass through dmz zone and ip addresses to pass through. but make sure on your comp u have spyware or something. Your ps3 can not get virus.

Hi! I will be more than glad to assist u in this concern..Please dont use the setup cd or setup wizard. you can access the setup page of the router by typing at the url:192.168.0.1 then it will ask for the user name and password, by default the username is admin and the password, leave it blank.. here are the things u need to check before u setup u router.. .. if you are using a cable modem from ur cable company provider- u need to do a mac clone on the router u have to clone the mac address of ur computer. normaly the mac of ur computer is the one register to your cable company and on the setup page of the router just selct on the internet setup, dhcp after clonning the mac address of your computer. u need to connect ur computer directly to the router and then after doing the process connect the router to the modem. if u are using a username and password, u have to use the pppoe settings on the router, if ur isp set a static ip , set it up to the router, to check the ip setting of your isp.. connect the computer directly to the modem and check if u have internet.. then click on start, run and type cmd,it will give u a dos prompt and from there type ipconfig/all and it will show u the ip address, subnetmask, default gateway, dns server.. I hope this will solve ur concern..

i have the same router. I recommend that you download a new driver of your lan card for your desktop pc, also if you have P2P and bittorrent applications, try to disable them first and see the difference, those programs slow down the your internet, because they hog your bandwidth and connects to multiple users.

I think you have wrong configuration of your router.

1. Some xDSL Internet Service Providers may assign a Fixed IP Address for your Broadband router. If you have been provided with this information, choose this option and enter the assigned IP Address, Subnet Mask, Gateway IP Address and DNS IP Address for your Broadband router.
2. If you connect to the Internet using an xDSL Modem and your ISP has provided you with a Password and a Service Name, then your ISP uses PPPoE to establish a connection. You must choose this option and enter the required information.
