Will Belkin 54G wireless router work with Cisco VPN Client?

[t-peng]

Few of our remote users are using Belkin 54G wireless router.

They are using various verisons of Cisco VPN Client 3.6 - 4.0.5 ..

We tried open following UDP ports on the wireless router:

AH 50, IKE 500, ESP15551

Without any success while user connected to the router via wired or wireless connection.

Would anyone have this type of experience with Belkin 54G wireless routers?

If you are trying to setup an IPSec tunnel between the Cisco VPN Client and the Belkin wireless router, I don't think that will work. As per the infrmation I could gain, 54G supports "Virtual Private Network (VPN) Pass-through"(http://www.broadbandbuyer.co.uk/Shop/ShopDetail.asp?CategoryID=647&ProductID=647). I would intepret that to mean that IPSec packets are sent through and not that the router can be used as an IPSec termination point.

Are you connecting to a central PIX, VPN Concentrator, or IOS Router?

As the Belkin router will be using NAT, you'll need to enable NAT Traversal (NAT-T) on your central VPN termination device. You'll need allow outgoing UDP 4500 traffic on the Belkin router too.

NAT-T is enabled by default in IOS 12.2(13)T and later, or there's an option on the concentrator, or "isakmp nat-traversal 30" on a PIX.
