Hi,
I have a problem with RDP-Connections within our L2TP/IPSec-VPN.
I'm able to ping the RDP-Server (w2k3) within the VPN-Tunnel. I'm able to connect to the RDP-Server from the LAN (and other VLANs) - routing works correct and RDP-Service is running.
But as soon as I try to connect to the RDP-Server within the L2TP/IPSec-tunnel I got a timeout message.
I've tried to set the MTU to 3000 and 5000 but no changes.
Further more I got a packet-filter rule called:
Source: IPSEC-Pool Service: ANY Destiantion: ANY
I only got a NAT from the IPSEC-Pool to the Internet (public-address) - do we need other NATting-rules?
I dont really know, how to find the problem ... there is nothing incorrect in the logs [:(]
Thanks a lot for your help in advance,

PS: I've started WireShark on the RDP-Server and got smth with "TCP checksum offload" and a lot of retrasmissions ... someone any idea? Thanks!
PPS: GOT IT - a static route was missing on the RDP-Server ... sry bothering you.
