accessing a VPN through a VPN..

[dingdongbell070]

At my company we have 3 different locations. The main location is connected two the other locations with a VPN to each one individually. Is it possible for one of the branches to connect to the other branch by accessing the main location through the VPN then accessing the other location through the second VPN? So essentially going through 2 different VPN's?

it will probably work, but may not operate reliably because of the amount of overhead involved with running the tunnel

Yes, as long as you use the correct hostnames/IP addresses to connect to VPNs... Like rendrag said, it might not be so reliable. That setup is quite a pain, though.

do you have router to router vpns in place?

if so cant you set up static routes at the main site that say something like

this.. (excuse the diagram) lol

{site 1} -- - - - --VPN - - - - -{site 2} - - -- - VPN - -- - - -{VPN}

10.0.0.x 192.168.1.x 172.16.0.x

static routes:

1) traffic from 10.0.0.x destined for 172.116.0.x - forward through the gateway for 192.168.1.x

2)traffic from 172.16.0.x destined for 10.0.0.x - forward through the other gateway at 192.168.1.x

this is assuming you have 2 routers at the main (middle site)

if not and its software VPN then a VPN within a VPN will work, however slowly and DNS may be an issue but it can be solved with the hosts file.

hope this helps
