Web Interface Settings Glossary 86
IP Menu
DNS Relay
Enables DNS requests.
When enabled, all DNS requests are forwarded to a remote DNS server. This is done
by matching the requested domain against the domain name assigned to each profile.
If a match is found, the profile is connected and the DNS request is forwarded.
Default: Enabled.
TFTP Server
Enables/disables TFTP (Trivial File Transfer Protocol).
When enabled, the Eicon 1550/1551 acts as a TFTP server and can respond to
upload or download requests from TFTP clients.
Default: Disabled.
IP Spoofing
Enables/disables spoofing. When enabled, all TCP keep-alive datagrams and all
Microsoft Server Message Block datagrams are spoofed. In addition, all NetBIOS over
IP name service traffic is dropped.
Default: Enabled.
IP Services
Defines the level of support provided for Microsoft NetBIOS services, which are
integrated into Microsoft TCP/IP. NetBIOS is required to support Microsoft Windows
Network Neighborhood, the MAP NETWORK option in Windows Explorer, and various
DOS-based networking commands (such as net use, net view, and net logon).
Choices:
• All: All NetBIOS traffic is forwarded to the remote site. This may result in substantial
connection charges unless you have a flat rate connection, as outgoing calls will be
made frequently.
• Intelligent: Provides full support for all Network Neighborhood functions, but spoofs
unnecessary traffic to reduce usage.
