TheRouter is a software packet router based on one of the fastest packet processing libraries. Using modern software technique such as QSBR, lockless data structures and cuckoo hashing enables the router to perform routing (up to 32Mpps) and CGNAT (up to 10 Mpps) on high packet rates using commodity hardware.

It supports

IPv4 static and dynamic routing. Dynamic routing is based on integration with Quagga Routing Suite or FRRouting
Dot1q and qinq ethernet encapsulations
IP unnumbered
ARP, proxy ARP
ICMP
PBR and multiple routing tables
Stateful and stateless firewall and various forms of NAT. This functionality is based on the improved version of NetBSD packet filter
Link Aggregation/Link Bonding/LACP
CGNAT (Endpoint-Dependent Mapping by NPF, Endpoint-Independent Mapping (EIM) by Deterministic NAT)
NAT events logging (IPFIX, Netflow v9)
VRRP (v2 for IPv4 and v3 for IPv6)
IPv6
- Unicast routing
- ICMPv6
- Neighbor Discovery Protocol
- Duplicate address detection
- Neighbor Unreachability Detection
- MLD v1, v2
- SLAAC
- VRRP v3
Flow accounting via IPFIX
QoS and HQoS
