I set up a WRV54G router/AP at my parents home, and it acts as a firewall for their cable internet connection, and AP for me when I'm there. I had hoped to use it for remote VPN access to their network, but I have had trouble getting the IPSec configured to allow this. I want to upgrade the WRV54G to the latest firmware version, but that will reset the configuration information and require all the settings to be manually entered again (including the port forwarding to my Linux box in their basement, which allows me SSH access to manage their network). I'm about 2000 miles away from them, so physical access is not an option. So, is there any solution for saving the configuration through firmware upgrades, or automating the config process so I don't have to walk my mother through the process of entering the required settings?
