I am attempting to setup a VPN from my home router to my business router, I have a linksys router at home that supports VPNs and a CISCO 1720 router at my business. My first question is in my work router there is no option to setup any kind of VPN there is a tunnel option but that does not seem to get me anywhere. Do I need a upgraded IOS version? or can i use the Tunnel command? My other question is when I setup the VPN from my home to my business router will all my packets that are destined for the Internet automatically go through the VPN and out through my business Router? My friend and I have been arguing for about 2 hours now about this.
First of all, you need an IPSec image (IOS) to configure VPN on your 1720.
download a IP PLUS IPSec 56 image of any version eg 12.2 below
- needs 8 MB Flash and 32 MB RAM
image name is "c1700-k8sy-mz.122-10a.bin"
Second question about internet, depends on what your home router is capable to do, on a Cisco router you specify Access-list on what to encrypt using source and destination networks, if the ACL does not match, your packet is forwarded to the normal default route to internet, if it matches, then it encrypts and sends to the peer router (eg; 1720)
