The HG 1500 can also set up a PPP connection to an ISP via one or more B channels. This
connection, too, can be used simultaneously by multiple clients in the IP network.
13.6.8.1

PPP, PPPoE and PPTP

The HG 1500 supports PPP (Point-to-Point Protocol) for both incoming and outgoing SCN con-
nections. PPPoE (PPP over Ethernet) and PPTP (Point-to-Point Tunneling Protocol) are sup-
ported for devices on the second LAN interface (typically an xDSL modem).
Connections from the LAN to the SCN are set up on the basis of the IP address addressed by
the LAN. The IP address is converted to a station number (this requires appropriate configura-
tion of the routing and dial tables). A prerequisite is that the remote station has a static IP ad-
dress.
After the connection has been set up, the HG 1500 can accept a dynamic IP address. Packets
for terminals in a local IP network are converted with NAT (see Section 13.6.8.2, "Network Ad-
dress Translation (NAT)").
There are various security and authentication mechanisms for PPP connections. Further de-
tails can be found in Section 13.6.8.3, "Access Protection".
