However, the port may be a problem. For example, in my case the following topology is used: cable_modem <-> VOIP_modem_also_DHCP_server_also_NAT <-> hub <-> my_computers. . The point/problem is I have no root access to VOIP_modem_also_DHCP_server_also_NAT , i.e. I can't assign a port of my liking to VPN traffic.
