Packet Filtering on the OnSite
Packet Filtering on the OnSite
The OnSite administrator can configure the OnSite to filter packets like a
firewall. IP filtering is controlled by chains and rules.
Chains
A chain is a kind of named profile that includes one or more rules that define
the following:
• A set of characteristics to look for in a packet
• What to do with any packet that has all the defined characteristics
The OnSite comes with a number of built-in chains. The OnSite administrator
can define additional chains and can edit the built-in chains. The built-in
chains are named according to the type of packet they handle, as shown in the
following list:
• INPUT - For incoming packets
• FORWARD - For packets being routed through the OnSite
• OUTPUT - For outgoing packets
As defined in the rules for the default chains, all input and output packets and
packets being forwarded are accepted.
