Each service type has one or more advanced options, but not all services support all advanced options. The default setting will work for most circumstances. Most of the time you can leave these values as-is unless a NetFoundry support engineer instructs you to change them.
By default, the gateway will hide the source IP of the client and present the gateway IP address as source IP for the client to access the target host for a service. The selection of the transparency option allows the source IP of client to be presented to the target host for the service rather than the gateway IP address.
Enable Permanent Connection
The permanent connection option can reduce the time required to setup the initial service connection for a client. By default, the transport connection will timeout after a period of time if there is no active data transfer. The selection of the permanent connection option can speed up the initial access to a service by creating an active transport connection.
The selection of data interleaving option can provide additional security as data interleaving will split data traffic of a session across several transport paths. The selection of the data interleaving option may affect total data throughput in certain cases depending upon packet sizes.
Enable ICMP (Ping) Tunneling
The selection of the Enable ICMP (Ping) tunneling option allows a ping to be tunneled through the host gateway to the target host. Only ICMP echo request/reply packets are supported.
Enable DNS Tunneling
The selection of the Enable DNS tunneling option allows clients to use the DNS resolver address(es) configured on the gateway to resolve DNS requests. The local client DNS lookup can be used in the event of a DNS request timeout from the gateway DNS resolves address(es).
