how to setup vpn on separate router and isp
Currently we have a network-A(192.168.1.x) with MS Exchange 2003 server, SQL server and DNS/DHCP/File server connected via a Watchguard Edge router to ISP-A.
We are setting up another office with a network to be connected by VPN to the main office.
My router supports VPN, but we would prefer to use a second ISP-B with a different router to establish the connection to our main office. This way we do not disturb the current setup which is working perfectly.
Can someone point me to the best way to set this up?
I have 2 network cards in the servers but we only use 1 at the moment.
Maybe I could use this one to setup a network-B(i.e. 192.168.2.x), but I don't know if I will get a conflict and if one side of the network will see the printer on the other.
Thanks for your help.

thanks for your input.
My current provider cannot provide ip-vpn but the second one offered us a "local loop". So if we get the point to point connection between the 2 offices without internet, I could setup just as you described?
Will I need to add routes in the router for office-B too.

Set the remote office subnet to 192.168.2.0/24
then set up the VPN back to main offices ISP-B router
in your watchdog router add a route for
destination 192.168.2.0/24 to go through your ISP-B's VPN device that is on you main offices subnet as say 192.168.1.2.
The easiest would be just to use the ISP and router you have. And if it too slow then pay for more bandwidth through ISP-A.
Or you can ask your ISP if they can do an IP-VPN for you across their network, maybe even an MPLS type cloud so you can get some QoS etc, and not go across the unpredictable latency of the public internet.
