I need few 4 different IP addresses in 4 different applications.
I thought that I can just use Wingate and socks in applications.
I have 4 VPN's configured (PPTP) - in PPTP I disabled option "use default gateway on remote network" because I want 4 vpn simultaneously:

My plan was:
APPLICATION1 -> SOCKS (127.0.0.1:8081) -> VPN1 -> internet
APPLICATION2 -> SOCKS (127.0.0.1:8082) -> VPN2 -> internet
APPLICATION3 -> SOCKS (127.0.0.1:8083) -> VPN3 -> internet
APPLICATION4 -> SOCKS (127.0.0.1:8084) -> VPN4 -> internet
I added socks servers in Wingate, but I can't add VPN (pptp device) as a gateway.
It is not listed there.
How I can connect VPN's to socks?
Or VPN to Proxy Service?
I searched over the internet for it about 5 hours and I don't found answer.
