Figure 35-15. Gateway Settings .. Proxy Ports Window Port Config tab
The Proxy Ports window Port Config tab allows configuration of Port Config rulesets (a.k.a. port
configurations), which are named sets of rules specifying which transport protocol/port
combinations are allowed, what management protocol will be used for a given transport/port, and
any port translations that should be applied. Once defined, Port Config rulesets can be referenced in
the Port Map rules, as configured on the Port Map tab.
To add a new Port Config ruleset, click the Add button. The Transport field indicates whether the
incoming request is using ICMP, TCP, or UDP. The RG Port field is the destination port
associated with the incoming request as received by the Ranger Gateway. The RG Port field may be
a single port number (eg 22) or a port range (eg 300-310). The Protocol field is the management
protocol to be used for the incoming request. The ZR Port field is the destination port that the
ZoneRanger should use when forwarding the request to the target device, or a translation rule that
can be used to calculate the port that should be used based on the rg-port. When the Transport
field is ICMP, all of the other fields are ignored.
To modify the name of a Port Config ruleset, right-click on the name in the Port Config list, and
click Modify. To remove a Port Config ruleset, right-click on the name in the Port Config list,
and click Delete.
To add a rule to a Port Config ruleset, click the empty field at the bottom of the Transport column.
To modify any of the fields in a rule, click on the individual field in the rule. To remove a rule from
a Port Config ruleset, select the rule and click the Delete button.
The Up and Down button can be used organize the Port Config rules. The Organize button will
reorder the rules so that they are grouped by transport protocol, with TCP rules listed first, followed
by UDP rules, followed by ICMP.
Port Config Cache Size is the maximum number of table entries cached by the Range Gateway in
memory to improve performance. The default is 100 entries with a valid range of 0 – 10000.
