Update to 1.9 broke my l2tp/ipsec

  Very strange behaviour. I updated my ER-8 to 1.9 an suddently I cannot access my server ILO4.

The L2tp config is the same unchanged:

l2tp {
     remote-access {
         authentication {
             local-users {
                 username xxx {
                     password xxx
                 }
             }
             mode local
         }
         client-ip-pool {
             start 172.16.44.111
             stop 172.16.44.120
         }
         dhcp-interface eth0
         dns-servers {
             server-1 8.8.8.8
             server-2 8.8.4.4
         }
         ipsec-settings {
             authentication {
                 mode pre-shared-secret
                 pre-shared-secret xxx
             }
             ike-lifetime 3600
         }
         mtu 1492
     }
 }

ILO4 of the server has IP 192.168.6.2 and is linked to the 6th ER-8 port (192.168.6.1)

Now the strange behaviour is like this:

1. VPN connects and I get a client IP 172.16.44.111

2. I have the following routes on the client

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         gateway         0.0.0.0         UG    100    0        0 enp4s0
10.0.0.0        0.0.0.0         255.255.255.0   U     100    0        0 enp4s0
10.255.255.0    0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
192.168.5.0     192.168.7.1     255.255.255.0   UG    0      0        0 ppp0
192.168.6.0     0.0.0.0         255.255.255.0   U     0      0        0 ppp0
192.168.7.0     0.0.0.0         255.255.255.0   U     0      0        0 ppp0
192.168.122.0   0.0.0.0         255.255.255.0   U     0      0        0 virbr0

3. I can ping 192.168.6.1. I can even ssh to that IP of the router.

4. I cannot connect to 192.168.6.2 or any other IP from that net.

5. Before 1.9 I was able to connect to 192.168.6.2

  What changed in 1.9 ?
