nftlb

nftlb a user-space tool that builds a complete load balancer and
traffic distributor using nftables.

Topologies supported: Destination NAT, Source NAT, Direct Server
Return and Stateless DNAT. This enables the use of the load
balancer in one-armed and two-armed network architectures.
Support for both IPv4 and IPv6 families.
Multilayer load balancer: DSR in layer 2, IP based load balancing
with protocol agnostic at layer 3, and support of load balancing of
UDP, TCP and SCTP at layer 4.
Multiport support for ranges and lists of ports.
Multiple virtual services (or farms) support.
Schedulers available: weight, round robin, configurable hash (per
IP, port, MAC or combination of them) and symmetric hash.
Support of configurable persistence or client-backend affinity with
a timeout (per IP, port, MAC or combination of them).
Support of security policies per service: white and blacklists
(from ingress), queuing to user space filter, filtering of bogus
TCP frames, maximum number of established connections, limit TCP
RST per second, limit new connections per second and more.
Priority support per backend.
Live management of virtual services and backends programmatically
through a JSON API.
