Client's connection speed decreeses greatly when connecting

[kalombo]

i'm using SE VPN SERVER for remote access to LAN.
There is over 20 MBpS (double-sided) connection on the gateway of my LAN.
When i'm connecting using SE VPN client connection speed decreases to 30 kbps even through i'm connecting from LAN machine.
What's the matter?

PS I'm sorry, my English is quiet bad.
