I have an idea regarding VPN remote connections and would like any expert to see if it will work. ANd here is my current situation :-
We have 3 sites - HQ, S1 & S2. S1 and S2 has a site-to-site VPN connection to HQ; there is NO connection between them. I have TWO Terminal Servers in HQ and remote connections are coming into different server - i.e. S1 comes to T1 and S2 comes to T2. All offices has its own static IP address from our ISP.
We would like to install additional broadband in our HQ to increase internet bandwidth. I understand we can have BONDED ADSL solution for additinal bandwidth and load balancing but they are not cheap. So I am wondering if we can get away with that, cheaply.
My proposal is, to install an additional ADSL line (with a new static IP) in our HQ. Put a new router (R2) in and create a site-to-site VPN to S2. Change the router in S2 so that its VPN is coming via the new line (change the static IP to the new IP given). Ports forward on R2 to T2. On T2, I shall change the Default Gateway pointing to R2 (192.168.0.253) while no change in T1 (still pointing to R1 which is 192.168.0.254).
So here is what I want to achieve :-
S1 comes in via R1 to T1
S2 comes in via R2 to T2
Will the above work? I sometimes need to use RDP to their servers (or workstations) - with two gateways in the HQ, I think I have to change the Default Gateway on my computer to 192.168.0.253 when I need to dial to S2.
Thank you for any advice.
