Configuring VoIP Access Rules
By default, stateful packet inspection on the SonicWALL security appliance allows all
communication from the LAN to the Internet and blocks all traffic to the LAN from the Internet.
Additional network access rules can be defined to extend or override the default access rules.
If you are defining VoIP access for client to use a VoIP service provider from the WAN, you
configure network access rules between source and destination interface or zones to enable
clients behind the firewall to send and receive VoIP calls.
If your SIP Proxy or H.323 Gateway is located behind the firewall, you can use the SonicWALL
Public Server Wizard to automatically configure access rules.
Tip Although custom rules can be created that allow inbound IP traffic, the SonicWALL security
appliance does not disable protection from Denial of Service attacks, such as the SYN Flood
and Ping of Death attacks.
