Docker client "Default route is configured but sysctl operations failed"

[DyllasDek]

Describe the problem

I try to access docker private network with Netbird docker image. I've already configured route node. When I try to curl/ping/wget from another client, i get request timeout.
Also on startup of the docker image I get WARN client/internal/routemanager/systemops/systemops_linux.go:175: Default route is configured but sysctl operations failed, VPN traffic may not be routed correctly, consider using NB_USE_LEGACY_ROUTING=true or setting net.ipv4.conf.*.rp_filter to 2 (loose) or 0 (off)

To Reproduce

Steps to reproduce the behavior:

1. Install client with netbird docker
2. Connect peer with each other
3. Configure route

Expected behavior

I should access private docker network
