in Connection and has the lowest latency. Latency checking packets are issued periodically to
a nearby router of each WAN connection to determine its latency value. The latency of a WAN
is the packet round trip time of the WAN connection. Additional network usage may be incurred
as a result.
Tip
The roundtrip time of a 6M down/640k uplink can be higher than that of a 2M down/2M up link because the overall
round trip time is lengthened by its slower upload bandwidth, despite its higher downlink speed. Therefore, this
algorithm is good for two scenarios:
● All WAN connections are symmetric; or
● A latency sensitive application must be routed through the lowest latency WAN, regardless of the WAN’s
available bandwidth.
14.2.8 Expert Mode
Expert Mode is available on some Pepwave routers for use by advanced
users. To enable the feature, click on the help icon and click turn on Expert
Mode
.
In Expert Mode, a new special rule, SpeedFusion
TM
Routes, is displayed in
the Custom Rules table. This rule represents all SpeedFusion
TM
routes
learned from remote VPN peers. By default, this bar is on the top of all custom
rules. This position means that traffic for remote VPN subnets will be routed to
the corresponding VPN peer. You can create custom Priority or Enforced
rules and move them
above the bar to override the SpeedFusion
TM
routes.
Upon disabling Expert Mode, all rules above the bar will be removed.
15 Inbound Access
15.1 Port Forwarding Service
Pepwave routers can act as a firewall that blocks, by default, all inbound access from the
Internet. By using port forwarding, Internet users can access servers behind the Pepwave
