I have just put on 5 Telstra highspeed ADSL connections in remote locations and i need to prepare my self before i fly to each site to configure these connections to work with our current VPN set up.
Telstra have supplied Cissco 850 routers for each connection.
What i need to know is in the next 2 weeks all my locations will have Cisco 850 routers and my head office will have a cissco model 1800 router for BDSL.
Do i set these routers into bridge mode and let my current Snap gear 530 boxes do all the authentication and VPN Ipsec tunnels like i previously had set up, or do i do away with the SG530s and let the cisscos do all the work.
My old network had normal ADSL connections with a adsl modem set to bridge mode passing all the authentication to the SG530s.
I then had IPsec tunnels set up between each location.
I have a server 2003 DC in each location and my main server 2003 DC (Global Catalog) is where the cissco 1800 will be located.
I am only new to networking, never used cissco devices before and with the previous net set up i had, i stumbled my way through it with the advice of a helpful guy from a small computer shop.
Whats the best sollution
