Site-to-site VPN extends the company's network, making computer resources from one location available to employees at other locations. The following are common Site-to-Site VPN architectures: Site-to-Site VPN single and multiple connection examples Using redundant Site-to-Site VPN connections to provide failover Configuring a Site to Site VPN between two SonicWalls on the same WAN subnet with same default gateway Aggressive Mode - Used when One Site has permanent/static public IP and the other site has a dynamic/temporary public IP address. For the demonstration scenario, I will use GNS3 network simulator to simulate the VPN tunnel between the two ends. (GNS 3, 2010). The diagram below shows site-to-site VPN – IPsec over GRE Tunnel: Figure 6: Site-to-site VPN -IPSec over GRE tunnel. For VOIP demonstration, I will use the following equipments: ADSL Cisco router (857)
Now they're planning to link 7 sites with firewall vpn site to site because 6 branch office need services hosted by principal A big site; this is really simple, because is enough to realize site to site vpn (redundant on two wan) from: A big site -> 1st branch office B1 A big site -> 2nd branch office B2 A big site -> 3rd branch office B3 and
