Project Description


We are interested in someone who can configure a tunnel for Voip traffic in highest quality as possible. We have tested PPTP, L2TP, GRE, OpenVPN and some other protocols and none of them worked so far. The country where we want to set the tunnel is under very restrict firewall.

I know someone who did this tunnel before with n2n protocol which im not familiar with it.
