Hello, I have deco M4 for 2 years and I am very happy with it. The only problem was always that I couldn't setup vpn on deco to steam to the countries I wanted. Yesterday I saw that some decos started supporting openvpn. So my question is 

1) Would x50 work with nord vpn, surfshark etc?

2) is there a guide?

3) is the speed good or it falls badly? 
 

(I will work it like router and not like access point if that matters. In fact I want my tv that gets internet from deco, to have vpn from it)
 

thanks in advance
