Adding User-Defined Relay Protocols
To add a relay protocol
- Navigate to NETWORK | System > IP Helper.
-
Click +Add in the Relay Protocols view. The Add Relay Protocol dialog displays.
-
Enable the IP Helper application by selecting Enable Application.
If this option is disabled, all IP Helper cache is deleted.
- Enter a unique, case-sensitive name for the IP Helper application in the Name field.
- In the Port 1 field, specify a unique UDP port number for the application.
- Optionally, in the Port 2 field, specify a second unique UDP port number for the application.
-
Optionally, specify the IP Helper cache timeout, in seconds, in an increment of 10 from 10 to 60, in the Timeout field. If a timeout is not specified, a default value of 30 seconds is selected.
This field is ignored if Raw Mode is selected.
- Choose a Mode to specify whether this protocol supports:
- Broadcast
- Multicast
- Both
- If you selected Multicast or Both for Mode, specify a valid multicast IP that this protocol is used in the Multicast IP field.
- To allow the source IP address to be translated when a packet is forwarded by an IP Helper policy, select Allow Source IP Translation. This option is selected by default.
-
To prevent a cache from being created when a packet is forwarded by an IP Helper policy, select Raw Mode. Unidirectional forwarding is supported. This option is not selected by default.
Any time set in the Timeout field is ignored.
- Click Save.
