Routing problems

So i have made a setup earlier and i have a problem i can't seem to figure out. I think it just need some route rules though. I have 3 different bridges:
1)bridge: contains 1 physical interface (ether5) and 1 logical (l2tp_1) and is configured with 1 network (192.168.10.1/24) (belongs to LAN_1 interface list)
2)def_bridge: contains 2 physical interfaces (ether2, ether3) and 1 logical (l2tp_2) and is configured with 1 network (192.168.11.1/24) (belongs to LAN_2 interface list)
3)wifi_bridge: contains 1 interface (wifi) and is configured with 1 network (192.168.1.1/24) (belongs to LAN_3 interface list)
**ether1 interface (WAN) belongs to WAN interface list along with 1 pppoe-out interface
PROBLEM IS:
1) 192.168.10.10 (in l2tp_1) doesn't ping the 192.168.11.100 (in ether3) but pings 192.168.11.101 (in ether2)
2) 192.168.10.100 (in ether5) doesn't ping the 192.168.11.100 (in ether3) but pings 192.168.11.101 (in ether2)
3) 192.168.11.11 (in l2tp_2) doesn't ping anything
Although all devices of the 3 networks have internet.

I hardly use L2TP any more. IPSec + IKEv2 is much saver and more stable.
Also it's allways a good idea to use a different subnet for VPN.

Maybe there's something blocking your packets in your firewall forward rules, could you please post your configuration?

Hello,

the correct Gatway is registered at the client 192.168.11.100 and there is no active firewall on the client which could block the ping?

In the first moment I would say in all cases if one client goes and the other does not then it is the client.
