    5.3 PPTP Encapsulation Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based networks. PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such as the Internet.

    6.1.5 NAT Mapping Types NAT supports five types of IP/port mapping. They are: 1. One to One: In One-to-One mode, the TELKOM ADSL 5100 maps one local IP address to one global IP address. 2. Many to One: In Many-to-One mode, the TELKOM ADSL 5100 maps multiple local IP addresses to one global IP address.

The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers.

    6.6 Configuring Address Mapping Ordering your rules is important because the TELKOM ADSL 5100 applies the rules in the order that you specify. When a rule matches the current packet, the TELKOM ADSL 5100 takes the corresponding action and the remaining rules are ignored. If there are any empty rules before your new configured rule, your configured rule will be pushed up by that number of empty rules.

    Type 1-1: One-to-one mode maps one local IP address to one global IP address. Note that port numbers do not change for the One-to-one NAT mapping type. M-1: Many-to-One mode maps multiple local IP addresses to one global IP address. This is equivalent to SUA (i.e., PAT, port address translation).
