https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D266586 Bug ID: 266586 Summary: vnet bridge with IP address is not working after reboot Product: Base System Version: 13.1-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: sharky@schaack.io Actually there is not documentation on how to implement vnet jails in the handbook . I did it my self years ago , but it would be handy to have a reference. I can provide it after we have discussed this problem.=20 My setup looks like the picture attached to the bug. This setup works excep= t , that the host can't use a service which are hosted inside a vnet jail.=20 People recommend me to move the ip from the "physical" lan interface to the bridge . I followed the advise and it works ! I can successfully use the service like dns or any other protocol which is hosted in the jail , until I reboot the machine and the rc.conf will takeover and create the setup for m= e . Instead it creates a mess , ip addresses are not set or the member is attac= hed to the bridge , but the ip address is not configured...=20 When the rc.conf create the setup for me the host is no able communicate anymore , because the IP addresses are not attached to the interfaces or the main lan interface is attached to the bridge but then the IP address is mis= sing . If I do the setup manually , it works.=20 Manually steps.=20 # vtnet0 does not have an IP address .=20 ifconfig bridge1 addm vtnet0 ifconfig bridge1 inet 192.168.10.100 netmask 255.255.255.0 ifconfig bridge1 addm vtnet0 ifconfig vnet0 up # Jails behind the bridge can be reached. The host system is able to ssh in= to the jail . To make it reboot stable I tried the following rc.conf cloned_interfaces=3D"bridge1"=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20 ifconfig_bridge1=3D"inet 192.168.10.100 netmask 255.255.255.0"=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 ifconfig_bridge1=3D"addm vtnet0" # after the reboot , the brigde1 does not have an IP address , but why ? I don't get it. # this fixes the issue ifconfig bridge1 inet 192.168.10.100 netmask 255.255.255.0 --=20 You are receiving this mail because: You are the assignee for the bug.=
