pfSense

In case of using several OpenVPN instances, e.g. Client (has its own default route) and Server on pfsense, assigned OpenVPN server interface does not send traffic via right route until device reboot (in some cases until pf restart).
I can see states and input traffic (10.0.10.0/24) on appropriate interface (OPT1) but does not see one output interface (LAN 10.0.11.0/24). Instead that I observe this traffic on WAN (default route) interface.

OPT1    icmp    10.0.10.2:1 -> 10.0.11.1:1  0:0     2 / 2   120 B / 120 B

IP 10.0.10.2 > 10.0.11.1: ICMP echo request, id 1, seq 157, length 40
IP 10.0.10.2 > 10.0.11.1: ICMP echo request, id 1, seq 158, length 40

IP 10.0.11.1 > 10.0.10.2: ICMP echo reply, id 1, seq 157, length 40
IP 10.0.11.1 > 10.0.10.2: ICMP echo reply, id 1, seq 158, length 40

IP 10.0.10.2 > 10.0.11.1: ICMP echo request, id 1, seq 137, length 40
IP 10.0.11.1 > 10.0.10.2: ICMP echo reply, id 1, seq 137, length 40
IP 10.0.10.2 > 10.0.11.1: ICMP echo request, id 1, seq 138, length 40
IP 10.0.11.1 > 10.0.10.2: ICMP echo reply, id 1, seq 138, length 40

The issue affects Intel and ARM
