Re: [pfSense] How much bandwidth is used in an idle OpenVPN connection using 2048 bit encryption?
Thanks. That's very good info. I think I can live with that. Your info gives me a good sense of go ahead with it and you will be safe but plan ahead for hardware and bandwidth needed. I will be creating a full notification system so I can be aware of the systems when they go down. These are all phone services so it's important to keep it all under radar the whole time. -Bruce On Sat, Sep 24, 2011 at 6:57 PM, Seth Mos seth@dds.nl wrote: The amount can be round off to the nearest 0. The number you ise for the actual encryption is large but does not directly correlate to the size of the idle traffic. The initial handshake is far more involved. If you enable keepalive you will always have a steady stream. On my work ipsec cluster with 350 nodes that ping to keep alive it is a few hundred kbit consistenly. I once calculated that a average site did 500 mb a month just on keep alive traffic. Regards, Seth typed on a tiny touchscreen, why exactly?

I am looking to have every client pfsense do an openvpn tunnel into my main pfSense box. I am using all Alix hardware. However, the client pfsense boxes are sometimes not very good with bandwidth and I don't want to spend the client bandwidth on OpenVPN specially when it's idel. I understand that even in idle mode there is traffic in between to keep the connection solid. Can someone tell exactly how much bandwidth is wasted or consumed if I keep a 24/7 connection?

Virtually nothing, 4 bytes every 10 seconds. Not enough to even be a consideration. ___ List mailing list List@lists.pfsense.org http://lists.pfsense.org/mailman/listinfo/list
