VPN Performance

Now that you've hung in through all the gory configuration details, I'll tell you how well the VP41 actually works! Linksys was kind enough to send me two VP41s so that I could do some performance testing. (Click on the link under the test results table below for details of the test setup.) I didn't really have any problems getting a tunnel successfully set up on pretty much the first try. I used the Subnet mode for both the Local and Remote group, and left one router set to its default 192.168.1.1 base address and set the other to 192.168.2.1, to put its LAN clients into a different subnet. Otherwise I accepted the Encryption, Authentication, and Key Management defaults (and didn't even enter a Pre-shared key), hit the Connect button and I was up and running!

The results show essentially the same performance in the two directions, except for the UDP streaming test, which I thought was odd. So I repeated this test, substituting a different computer on one end of the tunnel. Using this different computer, I got different results, so my conclusion is that the variance in the UDP streaming results is computer/OS dependent and not due to the VP41. 

At any rate, the performance through the IPsec tunnel is plenty fast and given the 1 to 1.5Mbps (on a good day!) speed of most broadband connections, probably won't even be an issue for most all users.
