Hi, =C2=A0=C2=A0=C2=A0=C2=A0 Thanks for the tip. I have slightly modified the file "/etc/rc.conf" and now the network is setup correctly. You have t= o note that the command "inet 172.16.0.11" (in the variable "ifconfig_bridge0") should appear first otherwise the address is not set. By the way, since there is 4 igb cards on this machine, it seems to be a good idea to add this instruction: kern.ipc.nmbclusters=3D"131072" in the file "/boot/loader.conf" as it is mentioned in the man page of the "igb" driver and in this link: =C2=A0=C2=A0 https://docs.netgate.com/pfsense/en/latest/hardware/tuning-and-troubleshoo= ting-network-cards.html best regards, =2D----------------------------------------------Functioning file rc.conf----------------------------------------------------------- #The configuration of the network.
