can it load balance between the two to give you higher speeds when doing multiple uploads/downloads, or does it provide fail-over functionality only if one of the connections goes down?
However you configure it. (Both is possible)
Take a look at the how-to's.
If you need trafficshaping of the vpn traffic using ipsec is currently the way to go as I know that this will be working with the upcoming shaper changes. OpenVPN shaping is not supported atm, same like filtering inside openvpn tunnels.
looking at this another way then. Is it possiable to forward on web traffic from squid to the ISA without losing the source IP address? As we are a school i have to keep track of what children are accessing.
Keep in mind the air is a shared media. The heavier the traffic gets the more likely collisions will happen and packages have to be resent or come in as garbage. If you want to simulate this without the wlan just drop in a switch and throw some of the clients connected on cablenics on that switch. Then retest. I bet it's the wlan and not pfsense.
A common issue on *nix boxes. If a file is open, but deleted, then du will not find it, but df will (correctly) report the space it is using. Until the file is closed the space isn't freed up.
We are still struggling to make COM port work on pfsense. Could anyone give us a simple script or any suggestions to make us to be able to receive data from COM port?
