VPN Setup
« on: June 24, 2009, 07:15:09 AM »
I am unable to get VPN to work at all since I upgraded to a 4500... Does anyone have any help or advice ?? I have done some googling and am seeing reports of the 4500 not supporting GRE-47, is this true ??

Everything worked fine on my old dlink router.. Any advice would be appreciated...

Adjust the NAT endpoint filtering to endpoint independent and disable SPI.

That did not work...  So just to be sure, I am defining 2 Virtual Server rules - TCP port 1723 & 47 to my server which i have setup for incoming vpn connections...

In the firewall section, I have unchecked Enable SPI
In each UDP & TCP Endpoint Filtering, I have selected Endpoint independent
In the ALG Configuration , all options are checked.


As of right now, the above configuration is not working.

Ahhh...more like latest, and not so greatest.

They all seem to have some port forwarding problems, and even getting a virtual server to work.

Wayner.

Try these settings:

FIREWALL SETTINGS
Enable SPI Checked

NAT ENDPOINT FILTERING
Both TCP and UDP Endpoint independant Checked

ANTI-SPOOF CHECKING
Unchecked

DMZ HOST
Unchecked

APPLICATION LEVEL GATEWAY (ALG) CONFIGURATION

IPSec (VPN) : NEEDS TO BE unchecked

All others checked


The last setting is the important one...You would think VPN needs to be checked but it wont work if it is.

Hope this helps!

Hope that they can release a new offical firmware asap.
