How do I setup our router to allow VPN client?

you are trying to connect to the VPN client.
Which VPN software you are using ?
To connect to the VPN , you will need to trigger ports on the router.
open the set up page of the router and trigger the ports on the router. The port numbers will be. 1723 , 10000-20000 , 443-447 , 500. Also reduce the MTU settings to 1365.
Disable the Block Internet request, you will find this option under security tab.
Make sure that the firmware of the router is up to date.

WRT120N doesn;t permit VPN accesses

Most times when VPN is not working is because one of the ports is not forwarding right. Easy fix is to go to router settings and enable DMZ for your computers IP address. Also you can actually find out what are the ports this VPN uses and go to Port Forwarding part of router and open the ports manually. My favorite is DMZ. All this does is open up ports for your computer IP address so there is no blocked pockets. Good luck.

I have a motorola wireless router and VPN will not establish a connection. I can access the internet, but no VPN

For VPN, you will have to open specific ports in your router . See this link..for what ports have to be opened.
To open the ports, you have to go to the webinterface of the router .
Hope this helps

Printing with Dlink DI-624S and VPN connection

I am guessing this VPN is something work related and not a VPN you setup yourself?? If that is the case your company's VPN access will not allow you to pass from there network back to yours which is why you are unable to print to your local home printer when connected to VPN. You might could run it by your IT staff and see if they will allow connection and help you set it up. If not then simply email the docs to yourself and then print them out after you are finished using VPN connection.

Hope this Helps

VPN client

Susan, if it is true that the router's firewall is blocking this traffic, you need to access the configuration of the router and open those ports up. Every router is different though, so I cannot just tell you generic'ly how to do this... So, what is the manufacturer and model of the router?

And to Vij.. did you hold down the reset button for up to ONE minute? this is a Hard Reset and will clear the firmware of most models.. just pushing the Reset button and releasing is known as a Soft Reset, and will NOT clear the firmware...

the following is from a nice guide i found on the net, see if it works for you: First thing to check is whether your router has any settings for PPTP or IPsec "pass through". These are commonly found in Linksys routers but you may have to hunt around for them on other makes. All you need to do is enable the setting for the VPN protocol that you're using, reboot your router and, if you're lucky, the VPN connection will come right up. Note: Not all routers have these enables and the lack of them doesn't necessarily mean that you can't get VPN working. Open up that Firewall Still no connection? The next step is to try opening some ports in your router's firewall to get your VPN connection made. In each case, you'll need to open the specific ports (and protocol) to the IP address of the computer that you're running the VPN client on. NOTE that port mappings work with only one computer at a time. If you have multiple VPN clients that you need to connect, your router will have to support the VPN protocol that you're using without requiring ports opened. If you're using Microsoft's PPTP protocol, TCP port 1723 is the port you'll need to forward to allow PPTP control traffic to pass. Figure 2 shows the Forwarding screen on a Linksys BEFSR41 set to forward this port to a client with IP address PPTP also needs IP protocol 47 (Generic Routing Encapsulation) for the VPN data traffic itself, but note that this is a required protocol, not a port. The ability to handle this protocol must be built into the router's NAT "engine"?which is true of most present-generation routers. IPsec-based VPN's need UDP port 500 opened for ISAKMP key negotiations, IP protocol 51 for Authentication Header traffic (not always used), and IP protocol 50 for the "encapsulated data itself. Again, the only "forwardable" item here is UDP port 500, which is also shown programmed in Figure 2 to the same LAN client machine?protocols 50 and 51 must be built into your router. Tip: Not all routers are created equal! Some allow only one VPN tunnel to be opened and used by a single client. Others support multiple tunnels, but with one client per tunnel. Unfortunately, most vendors don't make the VPN pass through capabilities of their products clear in their documentation, nor do they have support staff properly trained to provide this information either. In most cases, your only option is to try a router in your specific application, and make sure you can return it and get your money back if you can't get it working. Still not Working? Getting many IPsec-based VPN setups working can be a black art due to the wide variation in techniques used by various vendors. Although IPsec products have become more uniform as the technology matures, your company may use older, more proprietary products that may not be configured with NAT in mind, or require additional ports to be opened in your firewall.
