Import Geo IP Data in to Wireshark

Ever wondered or needed to know where all those network connections originate from or terminate to in a IP packet trace without querying individual IP's???


Wireshark can provide a map either from a wireshark packet capture or an import from another source eg Zyxel Firewall, producing the lovely looking map below.


This is the standard log output from a Zyxel, nothing exciting, honest. Ignore 192.168.0.247 attempting to establish a UDP port 500 Isakmp to somewhere not local to query time.


Enable a packet capture from the Diagnostic section and capture, add at least the external facing port, wan1. Once the capture has run for a while, stop and then export the files to the local computer where Wireshark is installed.
