18.3.3 DSL/Cable Optimization

DSL/cable-based WAN connections have lower upload bandwidth and higher

download bandwidth. When a DSL/cable circuit's uplink is congested, the download bandwidth

will be affected. Users will not be able to download data at full speed until the uplink becomes

less congested. DSL/Cable Optimization can relieve such an issue. When it is enabled, the

download speed will become less affected by the upload traffic. By default, this feature is

enabled.

19 Firewall

A firewall is a mechanism that selectively filters data traffic between the WAN side (the

Internet) and the LAN side of the network. It can protect the local network from potential

hacker attacks, access to offensive websites, and/or other inappropriate uses.

The firewall functionality of Pepwave routers supports the selective filtering of data traffic in

both directions:

● Outbound (LAN to WAN)

● Inbound (WAN to LAN)

The firewall also supports the following functionality:

● Intrusion detection and DoS prevention

● Web blocking

With SpeedFusion

enabled, the firewall rules also apply to VPN tunneled traffic.
