I recently purchased an 857 router for my DSL connection, and have been playing with it for several weeks. Currently I'm looking into implementing it as a VPN server, which would let me take my laptop somewhere out on the Internet and VPN back into my LAN.
However, despite my tedious searching, I haven't found any solid guidance on doing this. It seems like Cisco only wants you to use the 800 series as remote VPN endpoints, where the LAN clients communicate via VPN back to a central intranet (which is opposite of what I want to do).
I was hoping someone has accomplished this or something similar and could shed some light on the subject. Any input is much appreciated.
After much searching, thanks to Cisco's apparent inability to operate a wesbite, I think I've finally got it working as it should. Much of my configuration was taken from the "hub configuration" section here:
I'm also planning to write a paper on neat things to do with the 800 series routers in the future. Anyone who might be interested please let me know if there are any additional areas you'd like to see covered.
