Question

Want to establish a site to site VPN Tunnel

VPN Tunnel, VPN, SonicWALL, Firewalls

We have 5 different locations with Sonicwall firewalls as described under.

1. WS Corp TZ190W
2. MM Corp TZ170
3. MT Corp TZ170
4. MT Datacenter TZ170
5. IN Corp TZ170

We want to establish a site-to-site VPN tunnel, is switching to MPLS VPN a right move? If not then what should be do ?

I need more information! What are the links between the sites? If they are fast you can set your main office to be your central vpn endpoint and set access rules what can go where. What are you going to be doing over the lines? Is security an issue?

I fi that l2tp is the best well rounded protocol.
