Hi, all -- I would have called this a vpn, but after reading the recent [excellent] thread on what is or isn't vpn and what it can or can't do for one, maybe that's not the right term ... I have multiple sites A.comcast.net 192.168.a.0/24 B.att.net 192.168.b.0/24 C.localisp.net 192.168.c.0/24 ... that I would like to integrate into my own WAN and be able to see devices (machines, printers, etcetc) using the Internet as my transport medium. [NB that I don't have a proper router at most of these sites; I only have what the ISP gives me.] Better yet, when I'm on the road with a laptop I'd love to be able to connect into that and be part (just like remote office work). I was thinking that a host at each location, exposed through the firewall, would act as the local gateway and I could just route traffic across ... um, well ... that's where I run out :-) Is there any consumer-level software that will let me overlay a private network across multiple sites and encrypt the traffic between sites? And does each device in a site have two addresses (192.168.?.? and 172.16.?.?) or do I set each router's internal DHCP range to the larger network? Where do go to I learn about this stuff? :-) TIA again :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt
