How do I Synchronize and use my Belkin Router as VPN?

Check the Advanced tab of the N300's Firewall settings to see if VPN passthrough is enabled. If it's not, the firewall will cut off VPN communications.

You may also need to run the VPN Wizard on the N300.

Here's the manual:

hi - I just had a tough day trying to connect N150 to my company's VPN, and after a long struggle found out that Belkin N150 does not support the VPN connections. simply upgrade it to N300 and you would be fine.

Download the latest firmware from: http://belkin.com/support
Upon searching, you will three versions of this model available. As you didn't specify the version, you may select the appropriate.
Download and save it your desktop
Open router interface using: 192.168.2.1
Under utilities, click on Firmware Update
Browse, Locate the file(.bin) from your desktop, click on update
Click on Restore Factory Defaults under Utilities
Try to re-configure the router and forward ports that you want.
If this doesn't work, Enable DMZ for the private IP address you want.
That should certainly work.
It could also be your modem that may be blocking> Check this too
Only if you have NAT enabled modem, try to use this router as an access point
This would surely work

Firmware 1.00.23 fixes the VPN issue on the f5d8635 series.

Login to your Belkin router and check to see if there is a firmware update available for your specific model. If so, download and install it as this may resolve the problem without doing anything else. (Be sure to save your configuration first)

The specifications for a F5D9230 state that it supports VPN passthrough so you shouldn't need to configure anything in the router itself. It may be necessary to open a few incoming ports but only as a last resort.

Would you also reply to this post and specify...

1. What OS are you running on your pc?
2. What VPN client are you using on your pc?
3. Ask the administrator of the Exchange server if they're using PPTP or L2TP for VPN connections.

Another option would be to use OWA (Outlook Web Access) to access your email if it has been installed on the Exchange server.

I hade the same problem with mv Cisco VPN v5.0 and Belkin N1 router (F5D8231-4 v4...). I could only solve the problem with a new firmware (f5d8231-4 ww v4.00.18 at http://www.belkin.com/uk/support/article/?lid=enu&pid=F5D8231uk4&aid=9419&scid=0 ). I think this is a general firmware issue at Belkin. Good luck.
