WRT54G with Cisco VPN client?

    Hi,

    I'm trying to connect permanently a WRT54GL to a Cisco VPN but I can't. I'm currently using DD-WRT v23 SP1 but it doesn't seem to work. Any information about connecting a WRT54G to a Cisco VPN server ?

    Thanks

    You cannot use the Cisco VPN client to connect to DD-WRT v23SP1. There *are* some FAQs (try Google) for using the OpenVPN Client/Server built into the DD-WRT vpn version to connect OpenVPN Clients to your router.

    The Cisco VPN client uses proprietary "mode configuration" and xauth modes which along with its standards-based use of UDP port 500 in IKE Phase I, make it incompatible with OpenVPN.

    Thanks for the answer but I don't want to connect to the WRT54G with a Cisco VPN client. My goal is to connect a WRT54G permanently to a Cisco Pix.

    D'Oh! :cool: :whip: Your post *was* clear. I just can't read!

    Same problem, though. The DD-WRT OpenVPN doesn't use a standards-based IKE Phase I, opting for neither a pre-shared key nor a digital signature for authentication. It also doesn't used UDP port 500 in Phase I. That said, maybe there's a way to change the behaviour of OpenVPN. A little research on how it works is probably in order.

    You *could* use DD-WRT's PPTP client to connect to the PIX if the PIX isn't running 7.x code. Cisco has lobotomized PPTP server out of the new code base.
