Had anyone experienced problem with VPN over 3G network?
My customer connects to Internet using their PC with a 3G card installed. When he pings to his corporate VPN gateway, he gets average 400ms round-trip. When he connects to his company using VPN, the performance is very slow whereas web browsing is fast.
Info I gathered from the network admin is as follows:
- User should be using Cisco VPN Client 4.x
- The VPN box is VPN 3080 Concentrator, software version 4.1.Rel
- Dead Peer Detection (DPD) is enabled
Please advise if there's any known issue with VPN over 3G. Also whether there's any parameters to configure to make things work optimally.
