IPsec Tunnel is UP but no traffic

Question

Hi, 
 
 I established a IPsec VPN tunnel from my UTM 220 (Firmware version: 9.508-10) to an ASA 5525. 
 The tunnel is UP, but i can't ping/rdp into any remote host. 
 How can i tell if the problem is on UTM side or on the ASA side? 
 From the logs i cant tell where the problem is. 
 How can i begin to troubleshoot this? 
 
 Thanks

The UTM has Anti-Replay active, Gery. If the ASA does not, you get the problem you see. It's not possible to disable Anti-Replay on the UTM.
