What is the max throughput with 3DES on a 1721 router without the VPN module. I use a 1721 and a 3005 concentrator to establish an EzVPN connection over an ADSL link with 1.5Mbps downstream and 256Kbps upstream but I only get a thoughput of 210-240 Kbps in both directions. There is no difference if I use DES or 3DES.
I suppose with the VPN module I will get more throughput but max 240 Kbps sounds very low, so I suppose something is wrong. I also tested with a VPN dialer client against the same concentrator and then I get over 1Mbps with 3DES encryption.
