NOTE: if a server has one Internet IP address and multiple server names, and if one of the 
names is defined here, accesses to any one of the server names will also match this rule. 
Protocol and Port 
This setting specifies the IP protocol and port of traffic that matches this rule. 
Algorithm 
This setting specifies the behavior of the Pepwave router for the custom rule. 
One of the following values can be selected (note that some Pepwave routers provide only 
some of these options): 
●  Weighted Balance 
●  Persistence 
●  Enforced 
●  Priority 
●  Overflow 
●  Least Used 
●  Lowest Latency 
For a full explanation of each Algorithmn, please see the following article:

Terminate 
Sessions on Link 
Recovery 
This setting specifies whether to terminate existing IP sessions on a less preferred WAN 
connection in the event that a more preferred WAN connection is recovered. This setting is 
applicable to the Weighted, Persistence, and Priority algorithms. By default, this setting is 
disabled. In this case, existing IP sessions will not be terminated or affected when any other 
WAN connection is recovered. When this setting is enabled, existing IP sessions may be 
terminated when another WAN connection is recovered, such that only the preferred 
healthy WAN connection(s) is used at any point in time. 
12.5  Inbound Access 
Inbound access is also known as inbound port address translation. On a NAT WAN connection, 
all inbound traffic to the server behind the Peplink unit requires inbound access rules. 
By the custom definition of servers and services for inbound access, Internet users can access 
the servers behind Peplink Balance. Advanced configurations allow inbound access to be 
distributed among multiple servers on the LAN. 
Important Note 
Inbound access applies only to WAN connections that operate in NAT mode. For WAN connections that operate in 
drop-in mode or IP forwarding, inbound traffic is forwarded to the LAN by default. 
12.5.1 Servers 
The settings to configure servers on the LAN are located at Network>Inbound 
Access>Servers. 
Inbound connections from the Internet will be forwarded to the specified Inbound IP address(es) 
based on the protocol and port number. When more than one server is defined, requests will be 
distributed to the servers in the weight ratio specified for each server.
