VPN 3DES Encryption. What kind of bandwidth overhead comes with this encryption scheme?
Posted on 2003-11-13
I currently have ADSL through a company, 1436Kbs Download/256Kbs Upload. I am currently using a VPN solution with 3DES encryption. I have this ADSL VPN 3DES Encryption DSL Modem/Router at my office. When I connect to it fromhome, using drive/folder mappings or VNC it is Extremly Slow. If I use Windows Remote Desktop without the VPN and turn all the Remote Desktop settings to low, the session isn't so bad. I am wondering how much overhead this 3DES encryption might have, being that my upload speed is 256Kbs. Another thing is that I purchase this VPN solution from a DSL provider, and their solution is so you can have teleworkers and other VPN Remote locations (VPN Router to VPN Router). I am starting to think this not a viable situation:
Multiple Teleworkers and/or Multiple VPN locations.
Possiblility of people behind VPN router using up/down bandwidth.
All limited to 256Kbs.
Ok, the bandwidth is NOT their for someone to do what is listed above. I guess I am just more curious about the bandwidth overhead of 3DES, and how it would play along with a remote desktop application such as VNC.
