Interoperability
Web-based interface, ability to connect to other VPNs, number of trusted WAN and Ethernet ports.
Futureproofing
Encryption support, number of VPN tunnels supported and speed, extra features, such as AV scanning.
ROI
What kind of functionality do you get for your money?
Service
What is the duration of the service and availability from the vendors?
We tested the VPNs for the Scenario by setting up a network as follows:
- Client system A with address: 192.168.2.1
- crossover cable
- VPN device 1
- private address 192.168.2.254
- public address 144.205.26.201
Switch:
- VPN Device 2
- private address 192.168.1.254
- public address 144.205.26.200
- crossover cable
- Server A with address 192.168.1.1
| Product | Cyberguard | Fortinet | Juniper | Netgear | Nortel | SonicWall | Symantec | Watchguard |
| Lots of small | 37 | 30 | 31 | 37 | 33 | 23 | 27 | 28 |
| Medium | 20 | 11 | 11 | 22 | 20 | 10 | 18 | 11 |
| Large | 117 | 62 | 60 | 127 | 116 | 66 | 103 | 64 |
| Total Time | 174 | 103 | 101 | 185 | 169 | 99 | 148 | 103 |
| Speed in Mbit/Sec | 9.58 | 16.26 | 16.53 | 9.00 | 9.86 | 16.80 | 11.29 | 16.17 |
We then created a VPN tunnel between the two networks with Network Address Translation (NAT) so that the clients could all see each other. The VPN was Triple DES SHA1. We then mapped a drive from Client A to Server A and transferred three file sets to the server to give a representation of the VPN speed in Mbits/sec. The Juniper NS25 was used as the head end.
