VPN - msg = no route to <Public IP of Remote Firewall>, drop

[elyes]

Hello, 

I have a VPN built on 30E device 5.4.5. The tunnel comes up but it does not pass all the traffic. SNMP traps traps are being sent via the public IP. I don't understand why it is trying to route to the public IP of the remote firewall when trying to traverse the VPN tunnel and I don't know how a route could not exist since the Tunnel to that same Public IP is clearly up.

Here is what I get when I diag debug :

func=print_pkt_detail line=4903 msg="vd-root received a packet(proto=17, 10.*.*.*:162->10.+.+.+:162) from local. func=resolve_ip_tuple_fast line=4967 msg="Find an existing session, id-00001a19, original direction" func=ipsecdev_hard_start_xmit line=157 msg="enter IPsec interface-VPN" func=esp_output4 line=679 msg="no route to PUBLIC_IP, drop"

There is no other issue with other trafic :\
