Regex Editor & Tester

Matches multiple patterns common in firewall/security log entries: HH:MM:SS timestamps (hours 0-23), IPv4 addresses (four 1-3 digit groups separated by dots), dates in DD-MM-YYYY style with -, /, or . separators, and keywords like Permit, Global, Trust, Untrust, and WDeny (typical of Juniper NetScreen logs). Also matches words followed by two spaces and a digit. Useful for parsing, tokenizing, or extracting fields from firewall and network security logs.
