I purchased a 1721 router recently and I would like to know if it has 3DES. I would like to use the rouyter for vpn. If it does not have 3DES, how can I get it?

I also need to know how to restore the defaults and upgrade the IOS. When an IOS upgrade takes place, does it wipe out current values?

Does 1721 support a web interface?
