Dynamic-to-static routed VPN tunnel with Linksys router and ASA

Unanswered Question

I need to configure a dynamic-to-static routed VPN tunnel.  Basically a regular L2L VPN tunnel but where one side has a dynamic IP.

I have a Cisco ASA 5510 with ASA 8.2 (static IP).

I think the hard part is that I'm attempting to use a Linksys WRT54GL with DD-WRT firmware and VPNC to make the connection on the dynamic IP side.

I've read some litature on dynamic-to-static VPNs but I'm having problems making the leap with VPNC and DD-WRT.

Any suggestions would be appreciated.  Thanks

I have this problem too.

Make sure you are not running a vulnerable version of DD-WRT or you may be compromising the security of the site with the ASA 5510

Purchasing an ASA 5505 would be a good solution to help mitigate this risk.  Cisco puts out regular security advisories when know vulnerabilities are discovered.  I don’t believe the DD-WRT software has undergone the same amount of security testing as the ASA platform.  Depending on the level of security required at the primary site a commercial solution may be warranted.
