Bonjour, mes petites expériences d'hier: Le serveur dhcp du pfsense fournit la plage 192.168.201.10 - 192.168.201.245 en /24 Mon laptop: bash-5.1$ traceroute google.fr traceroute to google.fr (216.58.213.67), 30 hops max, 60 byte packets 1 gw-wifi.lipn.univ-paris13.fr (192.168.201.1) 2.209 ms 2.162 ms 2.156 ms 2 gw163.univ-paris13.fr (194.254.163.254) 4.034 ms 4.028 ms 4.023 ms 3 192.168.201.254 (192.168.201.254) 4.022 ms 4.002 ms 3.997 ms 4 192.168.210.254 (192.168.210.254) 5.089 ms 107.398 ms 5.335 ms 5 vl200-gi0-0-0-5-ren-nr-villetaneuse-rtr-091.noc.renater.fr (193.51.186.30) 3.978 ms 3.973 ms 3.968 ms etc. bash-5.1$ cat /etc/resolv.conf # Generated by NetworkManager search lipn.univ-paris13.fr univ-paris13.fr nameserver 192.168.201.1 # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default gw-wifi.lipn.un 0.0.0.0 UG 600 0 0 wlan0 loopback 0.0.0.0 255.0.0.0 U 0 0 0 lo 192.168.201.0 0.0.0.0 255.255.255.0 U 600 0 0 wlan0 Manips pfsense: désactivation dhcp + extinction: pas d'obtention d'IP rallumage pfsense: pas d'obtention d'IP réactivation dhcp + rallumage: Obtention d'une IP en 192.168.201.x Question: pourquoi des utilisateurs obtiennent-ils des adresses en 10. ??? À cause des baux fixes ? Passage de la patte LAN 192.168.201.1/24 -> 10.10.201.1/16 IPv6 Configuration Type: track interface -> none Note: - Erreur pfsense: "The Router Advertisements Server is active on this interface and it can be used only with a static IPv6 configuration. Please disable the Router Advertisements Server service on this interface first, then change the interface configuration." - Solution de contournement: Temporarily enable IPv6 on your LAN interface and set IPv6 configuration type to Static IPv6, then assign an IPv6 address like the IPv6 Loopback address ::1 or any other correct address like Googles DNS Server 2001:4860:4860::8888. The prefix and address doesn’t matter as this is only a workaround to disable the Router Advertisements Server. Then go to Services -> DHCPv6 Server & RA -> Router Advertisements -> Router mode and select Disabled Finally go back to your LAN interface and change the IPv6 Configuration Type back to None.

Question: pourquoi ? Autorisation au niveau du Cisco ? J'en suis là. Amicalement, Fred
