GPRS Advanced tabs
Log in The settings on this tab deal with IP and DNS
addresses.
The DNS address uniquely identifies your Internet
Service Provider (ISP)'s computers, which your P900
uses to connect to the Internet. Your P900 can
normally retrieve these addresses automatically from
most ISPs.
If, after setting up an Internet account, you cannot
connect to the Internet and you suspect these
addresses are incorrect, ask your ISP for their
primary and secondary DNS addresses.
An IP address consists of four 3-digit boxes, and the
valid input is between 000 and 256 in each box.
Proxy A proxy server is a computer connected between
your P900 and the computer you communicate with.
This arrangement can be used for connections to
Remote Sync servers, or within a company network.
If this setting is needed, your company's Information
Services department or Remote Sync provider must
give you instructions.
Other If your ISP supports Point-to-Point Protocol (PPP)
extensions, you can select the
checkbox. PPP extensions allow your P900 to
provide features such as encryption, which increases
the security of your Internet connection.
