Local Network, Universal Plug and Play, Dhcp Screen

Admin Settings

Local Network

•IP Address: (Default 192.168.15.1.) The Internet Protocol (IP) address of your IP8100 series telephone is private and cannot be seen on the Internet. You can change this number if needed, but it is usually not necessary to do so.

•Subnet Mask: (Default 255.255.255.0.) The subnet mask (sub-network mask) is used to deﬁne a list of IP addresses allowed to a speciﬁed network segment (i.e., the 192.168.15.x subnet).

•Local Domain Name (optional): If desired, you can enter a name here to identify

your network.

Deny WAN Ping: This option allows the IP8100 series telephone’s public WAN IP to ignore ping commands sent by Internet users. Hackers may ping public WAN IP address to determine whether an IP address is vulnerable. When defaults to Deny, this option instructs your network to ignore Ping queries and to help protect against unauthorized access by others outside your network.

VPN Pass-Through:(Default On) The IP8100 series telephone supports VPN (Virtual Private Network) pass-through for both PPTP (Point-to-Point Tunneling Protocol) and IPSec (IP Security). Turning both of these On prevents your IP8100 series telephone from blocking access to another network you may wish to use.

Universal Plug and Play

•Default is On. This option makes the IP8100 series telephone compliant with the Universal Plug and Play standard, which allows compatibility with equipment made by different manufacturers.

Remote Web Management

Default is off. If turned on, this feature allows you to change IP8100 series telephone settings from a remote location (i.e., via the Internet).

•IP Address: Enter the Internet IP address of a computer that has access to the IP8100 series telephone. You can use 0.0.0.0 to allow all Internet IP addresses access to your network.

•Port: Enter the port number used for access to the IP8100 series telephone.

Example: http://x.x.x.x:8080 (Where x.x.x.x is the WAN IP address of the IP8100 series telephone and 8080 is the port used for the web management interface.)

Remote SSH Management

If turned on, this feature allows Vonage to remotely troubleshoot the IP8100 series telephone via a secure shell (SSH). This feature is protected with an Admin password granted to Vonage support staff only.

•IP Address: Enter the Internet IP address of the remote computer, which will be allowed access to remotely conﬁgure the IP8100.

DHCP Screen

This screen allows you to view or change your local network IP settings.

When any device on your network is turned on, it must be assigned an IP address to communicate with other devices on the network. DHCP (Dynamic Host Conﬁguration Protocol) assigns these IP addresses to devices on your network.
