So I've got Tomato 1.25 on my linksys WRT54G router. It works great, but I'm wanting VPN features. So I found this: http://tomatovpn.keithmoyer.com/2009/08/125vpn34-release.html Which in turn referred me to these forums with any questions. I've done a great deal of search and still have some confusion. What's the proper way to upgrade from Tomato 1.25 to Tomato 1.25VPN? I see a patch file on the site listed above, but I'm not clear on what that is for. Do I use that in the upgrade process? Or do I just download the full flash update from here: http://tomatovpn.tomatomod.de/release/1.25vpn3.4/ ? Will upgrading wipe out my current settings on the router? If it does, will restoring a backup of my configuration after the upgrade break anything? Thanks for your help with what is probably an obvious question(s).
