Firewall ACL Rules

 

This allows you to create command-line ACL rules for many different firewall products, including Cisco IOS, Linux Netfilter (iptables), OpenBSD pf and Windows Firewall (via netsh). Rules for MAC addresses, IPv4 addresses, TCP and UDP ports, and IPv4+port combinations are supported.

It is assumed that the rules will be applied to an outside interface.

Lua

 

These options allow you to work with the Lua interpreter optionally build into Wireshark. See the “Lua Support in Wireshark” in the Wireshark Developer’s Guide.

Credentials

 

This allows you to extract credentials from the current capture file. Some of the dissectors have been instrumented to provide the module with usernames and passwords and more will be instrumented in te future. The window dialog provides you the packet number where the credentials have been found, the protocol that provided them, the username and the password.
