Ok – I have a strange scenario – any ideas on
this?
We have our OpenVPN 2.0.6 server at a datacenter hosting
site with lots of bandwidth and redundant connections on one IP – so that
part is fine
We have one office that the only cost effective connection
setup would be multiple DSL/cable links – a single high-bandwidth
connection would be $1000s more per month.
One theory was to use 3 different routers, and hard-wire the
3 subnets behind them, but that creates some in-efficiency for the local
devices talking across the VPN instead of locally. Printing from the
local machines would be very slow, etc.
Another scenario I’ve been thinking about is to have a
router with 4 interfaces – local and 3 isp. Then run 3 instances of
the openvpn client – tun0, tun1, tun2. Point each of these tunnels
over a specific ISP interface. Point specific traffic over the tunx
device that is proper, maybe by device/ip or maybe by service (eg: all mail
sending goes out tun0, all RDP traffic tun1, etc.)
Now the part I can’t figure out – the local subnet
(192.168.117.0/24) – will this confuse openvpn, since 3 clients would be
configured to have the same subnet behind it?
Thanks for your time,
