21 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)
● Internal Network (VLAN to VLAN)
The firewall also supports the following functionality:
● Intrusion detection and DoS prevention
● Web blocking
With SpeedFusion
TM
enabled, the firewall rules also apply to VPN tunneled traffic.
