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

follow the below config example

you can ignore the client config.

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.
