Take a look at this
https://community.openvpn.net/openvpn/wiki/RoutedLans
OpenVPN need to know how to send you to the other network
In the Router on Lan1 you need to see a route sending to tun0.
You can check router doing this:
route -n
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 x.x.x.x 0.0.0.0 UG 20 0 0 eth0.2
0.0.0.0 192.168.1.1 0.0.0.0 UG 30 0 0 eth0.3
10.18.0.0 10.18.0.2 255.255.255.0 UG 0 0 0 tun0
10.18.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 br-lan
192.168.1.0 0.0.0.0 255.255.255.0 U 30 0 0 eth0.3
192.168.1.1 0.0.0.0 255.255.255.255 UH 30 0 0 eth0.3
192.168.11.0 10.18.0.2 255.255.255.0 UG 0 0 0 tun0 <---- this line is the important!
xxx.xxx.xxx.xxx 0.0.0.0 255.255.255.248 U 20 0 0 eth0.2
In this case. 192.168.11.x is going to tun0 (the vpn interface)
