Question on network throughput

[gsdThreat360]

Forum,

This may seem like a dumb question but I want to make sure of network throughput with Untangle. I am using an Untangle System in the test lab but only with the lite packages just to see how everything works. I have 4 pc's behind it on a 100mb unmanaged switch. I wanted to know if Untangle can restrict the network throughput any from the computers on the inside getting out for downloading and uploading? I have just the filters that were pre-programmed into the system and no custom filters. So in a since it is straight out of the box with 100mb NIC cards. I am just curious if it impedes the network flow if any. http://forums.untangle.com/images/smilies/confused.png

Thanks ahead

Any filter put delay in the throughput compared to wire speed. But you are more secured and under policy.

Untangle has a free QoS function for bypassed traffic, and a paid Bandwidth Control module that does the rest.

Sky-Knight thanks for the information and I am using the QoS function. I am just trying to get the facts because I have HughesNet (I know it sucks) as my ISP that is supposed to give me 15Mb throughput but I am only getting 2 or 5mbs. They are saying it is my Untangle System but I am getting different results going out than they are. I want to make 100% sure before I blast them for poor throughput.

Thank again for the answers, currently I am just running it straight out the box so no filters on it. I just want to see how much it cuts down as I add filters.

Ahh, that's a different question. You'll need to rule out deficient hardware.

To do that the easiest way is to get into Untangle via SSH and run the following command.

/etc/init.d/untangle-vm stop

That will disable the Untangle filters and you'll be left with a linux router that's very similar to a linksys device. Run your tests, see how fast it goes. Then use /etc/init.d/untangle-vm start to bring Untangle back up.

Your speeds will only get slower once Untangle is actually working. If you can't run full speed with the VM off, you've got a hardware issue to sort out. But honestly it doesn't take much to get to 15mbit with Untangle. A single core P4 1.0ghz CPU, 1gb of ram, and a pair of Intel 10/100 NICs can easily do 20-30mbit.

The latency on a satellite connection is always going to be a problem, but that's not the same as bandwidth.
