DNS Relay
Enables DNS requests.
When enabled, all DNS requests are forward ed 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 Eicon1530 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.
• Minimal: Reduces NetBIOS traffic to a minimum. Does not support Network Neighborhood
functions. However, the MAP NETWORK option in Windows Explorer is supported, along
with DOS-based networking commands such as net use, net view, and net logon. This is the
most economical solution.
• None: All NetBIOS traffic is discarded.
