12.1 Speed Touch and IP
In this section all IP features of the STPro are shortly described.
The STPro has a preconfigured Net10" address: 10.0.0.138.
As the STPro IP layer supports logical multihoming (one interface
supporting multiple IP addresses), multiple manually configured IP
addresses and multiple dynamically assigned IP address(es) can
be active at the same time.
The STPro features a DHCP server.
Dynamic Host Configuration Protocol (DHCP) allows the PC(s) on
your local network to retrieve automatically an IP address from an
IP address leasing" server, i.e. a DHCP server.
See subsection 12.4 for more information.
The STPro features an IP router.
In general, IP Routing allows hosts to contact other hosts which
reside in other (sub)networks.
For the
STPro the main function of the IP router is to route IP
packets from the local network to the remote networks over
the ATM/DSL connections and vice versa.
See section 12.5 for more information.
The STPro features a combination of Network Address
Translation (NAT) and Port Address Translation (PAT) called NA(P)T.
Combined with the
STPro IP Router, NA(P)T allows multiple PCs to
share a single public IP address.
See section 12.6 for more information.
