Yes, it's possible. Use Proxifier application, it helps to bypass proxy an firewalls.
Sorry man, it's not the answer I was looking for. I know there a lot of applications that help to bypass firewall, but actually I can't use any of them because in that case I would lose the connection to my vpn (which I use to for work).
So, again: is there any other way to mine bypassig a proxy without using third part applications?
PS: sorry for my bad english
