[strongSwan] IPv6 tunnel and IPv4 traffic: no routing entries in table 220 ?

I wonder how the routing entries are written to table 220, and which are neccesary. Is there any place , like _updown for firewall rules, where I can see how and what is done ?

My problem:

If I use IPv4 tunnel and traffic, it's all ok, rules in table 220 appear and VPN works from LAN to LAN.
If I use IPv6 tunnel and IPv4 traffic, nothing appears in table 220. What can be the reason for such behavior ?

And, I was not able to find myself a rule that works, I tried to add to table 220 rules like

ip route add proto static scope global dev eth0 src table 220


(derived from strongSwan example https://www.strongswan.org/testing/testresults/ipv6/net2net-ip4-in-ip6-ikev2/ )

but it dont't work. VPN connection is up, but no ping from LAN to LAN, it seems the traffic is not thrown into tunnel (policy based VPN).


Can anyone please give a hint ?
