IKE and IPSEC timers on slow connection

Hello,

Does anyone has recommandations regarding phase1/2 timers for ipsec tunnels via a gprs/umts connection?

Is normal ipsec preferable (udp) or tcp?

Thx!

Re: IKE and IPSEC timers on slow connection

The General Packet Radio System (GPRS) facilitates the transition from phase1/2 GSM networks to 3G UMTS networks. The GPRS supplements GSM networks by enabling packet switching and allowing direct access to external packet data networks (PDNs). Data transmission rates above the 64 kbps limit of integrated services digital network (ISDN) are a requirement for the enhanced services supported by UMTS networks. The GPRS optimizes the core network for the transition to higher data rates. Therefore, the GPRS is a prerequisite for the introduction of the UMTS.
