Title: ipsec slow transfer speed
Post by: zaiby on April 12, 2010, 08:42:22 AM

Hi I have dfl-860 + dfl 210 i my office

dfl 860 has 20mbit/10mbit
dfl 210 has 20mbit/5mbit

They r connected using ipsec tunnel with "High" Algorithms.

My problem is when I transfer files through the tunnel it only send it with a speed of 400kb/s max, how can that be? and how do i correct that?

How are you testing that speed?

What is the CPU and memory usage like on both sides?

Any log entries we should know about?

Try 1416.

Ohh and assuming neither DFL is behind NAT what speeds do you get in transport mode?

Thanks for the answers but it seems to be working now, full speed both ways I did a restart on all the equipment
