I did some VPN speed tests and found big differences when using different transfer methods for upload/download (comparing ftp, smtp/pop and explorer drag/drop).
I have a home cable modem (best speed around 400 kbit/sec).
FTP transfer of 30 Mb file:
---------------------------
Upload Home->PIX->Server - 588 seconds
Download Server->PIX->Home - 83 seconds
Explorer Drag/Drop of 30 Mb file:
---------------------------------
Upload Home->PIX->Server - 900 seconds
Download Server->PIX->Home - 900 seconds
I have not tested yet, but SMTP/POP seems even slower.
Config Details:
- PIX-506E does PAT to a single static IP
- IPSEC with a split-tunnel configuration
- Currently using DES (plans for 3DES???)
- Windows 2000 clients, using VPN Client 3.5.1(B)
- OS 6.1(3)
- I am able to authenticate (W2K IAS/RADIUS) and connect to the internal LAN okay (I can browse the NN, access shares, ping etc) with some initial delays
- DNS and WINS work well
- I am the only user using the internal LAN/VPN and did tests under low traffic conditions
- My home client is behind a DLink gateway (IPSEC pass-thru) although I have tested without this without much difference...
Anyone have any ideas why there is such a high dependence on direction and transfer methods?
I still plan to create a totally seperate LAN on the outside to test more precisely (ie remove my ISP from the loop).
