What is PfSense Site to Site VPN Overhead
I would like to have an idea about the approximate overhead between two sites running pfsense and set up site to site vpn.
In other words, what is your throughput percentage over vpn?
Although there are many dependencies, there should be percentage scale between minimum and maximum.
Thank you in advance for your time.
I have two sites with 100Mbps down and 20 Mbps up. With Ipsec I was getting speed around 300 KBps from one site to another but when I switched to OpenVPN for my site to site connections I'm getting 20Mbps , when doing a speedtest from http://seedtest.comcast.net I'm getting 21.59Mbps. So I would say the overhead is very little. I am running a AMD Athlon X2 Dual Core Processor BE-2350 with 4GB or RAM for my box. I am very happy with OpenVPN, not only am I getting a lot better performance but my connections never go down. With IPSec my sites would go down a couple of times a week.
Hope this helps.
Interesting. Are you using compression on the link? Were you before? (over IPSec)
No compression. Not sure what the issue was but very happy now. I should mention I'm using 2.1 RC at home I'm using 64 bit at work I'm using 32 bit. Maybe Comcast is doing something? But I haven't heard anything and I work there so I would have probably heard something.
