Features:
- Add exclude_source_ips configuration option
- Support single IPs (192.168.1.1) and CIDR ranges (10.0.0.0/8)
- Filter packets in parser before TLS processing
- Log exclusion configuration at startup
- New ipfilter package with IP/CIDR matching
- Unit tests for ipfilter package
Configuration example:
exclude_source_ips:
- "10.0.0.0/8" # Exclude private network
- "192.168.1.1" # Exclude specific IP
- "172.16.0.0/12" # Exclude another range
- "2001:db8::/32" # IPv6 support
