Port Forwarding (DNAT)

Port forwarding allows remote computers (e.g., computers on the Internet) to connect to a specific computer

or service within a private local-area network (LAN). The following is an FTP port forwarding example.

echo 1 >/proc/sys/net/ipv4/ip_forward

modprobe nf_nat_irc

iptables -t nat -A PREROUTING -p tcp --dport 99 -i eth0 -j DNAT --to-destination 192.168.126.100:

PPP (Point to Point Protocol) is used to run IP (Internet Protocol) and other network protocols over a serial link.

PPP can be used for direct serial connections (using a null-modem cable) over a Telnet link, and links

established using a modem over a telephone line.

Ethernet port. Since PPP is a peer-to-peer system, the ioPAC RTU controller can also use PPP to link two

networks (or a local network to the Internet) to create a Wide Area Network (WAN).

The pppd daemon is used to connect to a PPP server from a Linux system. For more detailed information about
