We have a site to site vpn setup with a cyber roam cr35ing on one end (and 10mbps up/down dedicated line) and a sonicwall TZ215 on the other end (with 50mbps up/down). The main purpose of the tunnel is to reroute all traffic (and essentially act as a tunnel) from the cr35ing to the TZ215 since specific websites our company uses are restricted by IP.
Currently with an IPSEC tunnel we are getting about 3mbps up/1.4mbps down on the cyber roam end. I am thinking of switching over to PPTP or no encryption even to check if it's possible to increase the speeds further.
My question is, if I disable encryption, the tunnel should essentially work like a normal day to day connection correct? Any and all input on this matter will be appreciated.
