Because when you want to browse free it will happen, so better check with he hotel/fastfood or airport IT admin, he would have blocked it.
Good Luck

I am unable to access my company's vpn server.


You may have some needed firewall ports blocked on your router. Turn off the firewall temporally and see if your able to connect. Your company IT folks should be able to tell you what ports they need open.

Use the web interface to administrate settings.

Go to Advance > Default DMZ Server and enter the computers IP that needs VPN access. This will bypass routers NAT / Firewall, and allow all network ports access.

The router's PPTP passthrough and IPSec settings assume that you're connecting to an external VPN server on the public side of the network, but it sounds like you're hosting your VPN server inside your local network. If this is the case, you may just want to have your windows VPN box in a DMZ, or get a router that you can exert more control over. Be wary, if you're doing this at a residential location, your internet provider will probably block or "shape" this type of incoming traffic to your local network.

1. login to router as usual, but find a setting called default dmz server
2. enter the IP address of your PS3 as the dmz server (to see what your ps3's ip is go to network > connection settings and have a look.

this should definitley make it a nat 2 - but try the first method

Nat help


Hi jman92592,


Here are some options with that router. Some online games and videoconferencing applications are incompatible with NAT. The WGR614 router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local PC can run the application properly if that PC’s IP address is entered as the default in the PORTS Menu. If one local PC acts as a game or videoconferencing host, enter its IP address as the default


To set up an additional computer to play games like Half Life, KALI or Quake III:
1.Click the button of an unused port in the table.
2.Select the game again from the Service Name list.
3.Change the beginning port number in the Start Port box. For these games, use the supplied number in the default listing and add +1 for each additional computer. For example, if you've already configured one computer to play Hexen II (using port 26900), the second computer's port number would be 26901, and the third computer would be 26902.
4.Type the same port number in the End Port box that you typed in the Start Port box.
5.Type the IP address of the additional computer in the Server IP Address box.
6.Click Apply



The WAN Setup options let you configure a DMZ server, change the MTU size and enable the router to respond to a Ping on the WAN port.

Connect Automatically, as Required

  • Normally, this option should be Enabled, so that an Internet connection will be made automatically, whenever Internet-bound traffic is detected. In locations where Internet access is billed by the minute, if this causes high connection costs, you can disable this setting.
  • If disabled, you must connect manually, using the sub-screen accessed from the Router Status menu "Show WAN Status" screen.

•Disable SPI Firewall

  • Normally, this option should be Enabled, so that your local network will be protected by the Stateful Packet Inspection (SPI) firewall included in the WGR614. However, certain communications functions like VPN may require turning off the SPI feature.
Setting Up a Default DMZ Server

  • The default DMZ server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local PC can run the application properly if that PC’s IP address is entered as the default DMZ server.
Note: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall, and is exposed to exploits from the Internet. If compromised, the DMZ server can be used to attack your network.

The WAN Setup menu, shown below lets you configure a Default DMZ Server.

  • To assign a computer or server to be a Default DMZ server, follow these steps:
1.Click WAN Setup link on the Advanced section of the main menu.
2.Type the IP address for that server. To remove the default DMZ server, replace the IP address numbers with all zeros.
3.Click Apply.

Good Luck and don't forget to leave a rating.

Thanks Mark

Vpn


this is not so much a soloution but an idea!
from memory the netopia devices allow you to configure a dmz device by IP or MAC address.

I have had to do something similar but with a buffalo unit instead of your linksys. I ended up having to place the buffalo unitin into a dmz created on the netopia unit. before VPN tunnles were formed correctly.

Vpn error. 800


Resolutions: 1) if you have firewall, open TCP Port 1723, IP Protocol 47 (GRE). 2) make sure you can reach the VPN server by using ping. Sometimes, poor connection can cause this issue too. 3) You may need to updated firmware on a router or firewall if other OS (win9x/nt/me/w2k) works except XP. 4) The VPN server may not be able to get IP from DHCP for the VPN client. So, you may want to re-configure VPN host networking settings. For XP pro VPN host, go to the Properties of the VPN>Network, check Specify TCP/IP address and Allow calling computer to specify its own IP address, and uncheck Assign TCP/IP addresses automatically using DHCP. 5) Make sure no other secure software blocks your access, for example, if you use Norton secure software, you may need to add the remote client's IP so that the client can access. 6) If your VPN running on a Windows RRAS with NAT enabled, you may want to check the NAT settings. 7) If you can establish the VPN from the desktop at home but not from the laptop. Make sure no security software like Microsoft OneCare software that blocks the GRE.
