Answer 1

I don't know if it's right or wrong, but I figured it out.
I wrote this in the client config

route-nopull

# vk.com
route 87.240.160.0 255.255.224.0
route 95.213.0.0 255.255.128.0
route 185.32.248.0 255.255.255.0
route 95.142.192.96 255.255.255.224 
route 95.142.192.128 255.255.255.128
route 95.142.193.0 255.255.255.0
route 95.142.194.0 255.255.254.0
route 95.142.196.0 255.255.252.0

route 87.250.251.0 255.255.255.0
route 93.158.134.0 255.255.255.0

and it worked as it should!
