I just purchased a Cisco 806 router on Ebay with 16 MB of ram / 12 mb flash. It will take some time to arrive, but I thought I'd ask some general questions right now. I am not sure which IOS version is included. My questions: 1. Is this amount of ram sufficient for running (any type of) VPN, or do I need to upgrade to 32 MB of ram ? 2. Does a "basic" (non-3des) IOS image for 806 support any type of VPN encryption? 3. Can I expect to be able to establish VPN tunnels with consumer-grade VPN routers, such as Linksys BEFVP41 and if so, do I need an "optional" IOS image or will a base image do ? 4. Can I use a VPN client to connect to the 806 (such as Cisco VPN Client, Greenbow, or SecurePoint) or does this router only support VPN tunneling to other Cisco VPN routers ?
Thank you in advance for your answers, and sorry if the amateur hour seems a little high!
