Ho lokolloa ha sebopeho se tsitsitseng ho fumaneha ho nolofatsa ho theha marang-rang a marang-rang - NetworkManager 1.40.0. Li-plugins bakeng sa tšehetso ea VPN (Libreswan, OpenConnect, Openswan, SSTP, joalo-joalo) li ntlafatsoa e le karolo ea potoloho ea tsona ea ntlafatso.
Mekhoa e mecha ea NetworkManager 1.40:
- Khokahano ea mola oa taelo ea nmcli e sebelisa folakha ea "--offline", e lumellang ho sebetsana le li-profiles tsa khokahano ka sebopeho sa keyfile ntle le ho fihlella ts'ebetso ea morao-rao ea NetworkManager.

- Ts'ehetso e ekelitsoeng bakeng sa MPTCP (Multipath TCP), katoloso ea protocol ea TCP bakeng sa ho hlophisa ts'ebetso ea khokahano ea TCP le ho tsamaisoa ha lipakete ka nako e le 'ngoe litseleng tse' maloa ka marang-rang a fapaneng a marang-rang a amanang le liaterese tse fapaneng tsa IP. Hona joale NetworkManager e khona ho laola liaterese tsa IP tse phatlalalitsoeng kapa tse sebelisoang ho phallo e eketsehileng ea MPTCP, ho kenyelletsa le ho lokisa liaterese tsena ka bohona, ho tšoana le kamoo mokhoa oa mptcpd o etsang kateng. NetworkManager e boetse e tšehetsa ho nolofalletsa MPTCP ho kernel ka ho beha sysctl /proc/sys/net/mptcp/enabled le ho beha meeli e boletsoeng ke "ip mptcp limits" taelo. Ho laola ts'ebetso ea MPTCP, ho na le thepa e ncha "connection.mptcp-flags" e hlahisitsoeng, eo ka eona u ka nolofalletsang MPTCP le ho khetha litekanyetso tsa kabelo ea aterese (signal, subflow, backup, fullmesh). Ka nako e sa lekanyetsoang, MPTCP e lumelloa ka bo eona ho NetworkManager haeba sysctl /proc/sys/net/mptcp/enabled e behiloe ka har'a kernel.
- Hoa khoneha ho ngola li-parameter tse tlamang aterese ea IP bakeng sa DHCP (DHCP lease) faeleng /run/NetworkManager/devices/$IFINDEX (tlhahisoleseding e bolokiloe likarolong [dhcp4] le [dhcp6]), e leng se u lumellang hore u tsebe ho tlamahane ka mokhoa o bonolo. ho bala faele ntle le ho fumana D -Bus kapa tsamaisa taelo "nmcli -f all device show eth0".
- Ipv4.link-local parameter e kentsoe profaeleng ea khokahanyo bakeng sa ho tlama lihokelo tsa lehae tsa IPv4 ho liaterese tsa intranet 169.254.0.0/16 (IPv4LL, Link-local). Nakong e fetileng, liaterese tsa IPv4LL li ne li ka hlalosoa ka letsoho (ipv4.method=link-local) kapa li fumanoa ka DHCP.
- E kentse parameter "ipv6.mtu" ho lokisa MTU (Maximum Transmission Unit) bakeng sa IPv6.
- Khoutu e tlositsoe ts'ebetsong e sa sebelisoeng ea bareki ba DHCPv4 ho latela khoutu e tsoang ho systemd. Ts'ebetso ea n-dhcp4 ho tsoa ho sephutheloana sa nettools esale e sebelisoa joalo ka moreki oa DHCP.
- E nolofalitse DHCP ho qala bocha ha aterese ea MAC e sesebelisoa e fetoha.
