Understanding RPC ALGs

JUNOS Software supports basic Remote Procedure Call Application Layer Gateway (RPC ALG) services. RPC is a protocol that allows an application running in one address space to access the resources of applications running in another address space as if the resources were local to the first address space. The RPC ALG is responsible for RPC packet processing.

The RPC ALG in JUNOS Software supports the following services and features:

• Sun Microsystems RPC Open Network Computing (ONC)
• Microsoft RPC Distributed Computing Environment (DCE)
• Dynamic port negotiation
• Ability to allow and deny specific RPC services
• Static Network Address Translation (NAT) and source NAT (with no port translation)
• RPC applications in security policies

Use the RPC ALG if you need to run RPC-based applications such as NFS or Microsoft Outlook. The RPC ALG functionality is enabled by default.
