Does Easy VPN use UDP?

By default, the Easy VPN hardware client and server encapsulate IPsec in User Datagram Protocol (UDP) packets.

If your environment allows UDP, however, configuring IPsec over TCP adds unnecessary overhead.

This could cause routing issues when the VPN client needs to access different subnets within the 10 network over different interfaces.
