UTM cant communicate through tunnel

brohall
I have a strange problem where all communication through the IPSec tunnel works but the UTM on one side can not communicate with any machines on the other side of the tunnel. It is like the UTM doesn't know its own routes and tries to talk through the default gateway instead of though the tunnel.

Are there any specific rules/routing that I have to set up to let the UTM communicate with the machines on the other side of the tunnel?

    tcpdump on the wan network show both encrypted traffic between the networks and unencrypted traffic from the UTM to the remote network:
    10:49:10.100361 MY.PUBLIC.IP.1 > MY.PRIVATE.IP.1: icmp: echo request (DF)
    10:51:18.603432 esp MY.PUBLIC.IP.1 > MY.PUBLIC.IP.2 spi 0x94aa9333 seq 3551 len 1476 (DF) [tos 0x10]
