* fix(router): nft tables limit number of peers source batching them, failing at 3277 prefixes on nftables v1.0.9 with Ubuntu 24.04.3 LTS, 6.14.0-35-generic #35~24.04.1-Ubuntu
* fix(router): nft tables limit number of prefixes on ipSet creation
adds NetFlow functionality to track and log network traffic information between peers, with features including:
- Flow logging for TCP, UDP, and ICMP traffic
- Integration with connection tracking system
- Resource ID tracking in NetFlow events
- DNS and exit node collection configuration
- Flow API and Redis cache in management
- Memory-based flow storage implementation
- Kernel conntrack counters and userspace counters
- TCP state machine improvements for more accurate tracking
- Migration from net.IP to netip.Addr in the userspace firewall
This specifically concerns the established/related rule since this one is not compatible with iptables-nft even if it is generated the same way by iptables-translate.
* Optimize rules with All groups
* Use IP sets in ACLs (nftables implementation)
* Fix squash rule when we receive optimized rules list from management
