External Firewall Configuration

In many deployment scenarios, an external firewallFirewall is a network security system used for preventing unauthorized access to or from a private network. is situated between Aruba devices. This chapter describes the network ports that need to be configured on the external firewallFirewall is a network security system used for preventing unauthorized access to or from a private network. to allow proper operation of the Aruba network. You can also use this information to configure session ACLsAccess Control List. ACL is a common way of restricting certain types of traffic on a physical port. to apply to physical ports on the managed device for enhanced security. However, this chapter does not describe requirements for allowing specific types of user traffic on the network.

 

A managed device uses both its loopback address and VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. addresses for communications with other network elements. If the firewallFirewall is a network security system used for preventing unauthorized access to or from a private network. uses host-specific ACLSAccess Control List. ACL is a common way of restricting certain types of traffic on a physical port., those ACLsAccess Control List. ACL is a common way of restricting certain types of traffic on a physical port. must specify all IP addresses used on the managed device.
