Peplink Balance Series

Appendix C. Case Studies

C.1 Performance Optimization

C.1.1 Scenario

In this scenario, email and web browsing are the two main Internet services used by the LAN users.

The mail server is external to the network. The connections are ADSL (WAN1, with slow uplink and fast

downlink) and Metro Ethernet (WAN2, symmetric).

C.1.2 Solution

For optimal performance with this configuration, individually set the WAN load balance according to the

characteristics of each service.

 Web browsing mainly downloads data; sending e-mails mainly consumes upload bandwidth.

 Both connectionsoffer good download speeds; WAN2 offers good upload speeds.

 Define WAN1 and WAN2's inbound and outbound bandwidths to be 3M/512k and 4M/4M

respectively. This will ensure that outbound traffic is more likely to be routed through WAN2.

 For HTTP, set the weight to 3:4.

 For SMTP, set the weight to 1:8, such that users will have a greater chance to be routed via

WAN2 when sending e-mail.

C.1.3 Settings

1. Add a new outbound traffic rule for HTTP.

2. Add a new outbound traffic rule for SMTP.

In general, to add a new outbound traffic rule, navigate toNetwork> Outbound Policy:
