IPSec VTI not working

[barsigor]

Hi
I have a problem with an IPV4 IPSEC VTI, this is the configuration

PFSENSE 1
IPSEC P2 (VTI):
Local subnet: address 10.10.10.1
Remote subnet: address 10.10.10.2

IPSEC1 interface assigned to VTI
gateway for IPSEC PtP (gateway 10.10.10.2)

in the route table i have:
10.10.10.1 link#9 UHS 18 16384 lo0
10.10.10.2 link#12 UH 17 1400 ipsec2

PFSENSE 2
IPSEC P2 (VTI):
Local subnet: address 10.10.10.2
Remote subnet: address 10.10.10.1

IPSEC1 interface assigned to VTI
gateway for IPSEC PtP (gateway 10.10.10.1)

in the route table i have:
10.10.10.1 link#7 UH 8 1400 ipsec1
10.10.10.2 link#2 UHS 10 16384 lo0

I see icmp packets on the ipsec interfaces (even if i disabled keepalive) but i cannot ping from one firewall to another.

There's anything else i can check ?
Thanks,
Igor
