vnet

I have a problem getting dhcpd to run inside a iocage controlled jail. Following various bits and pieces found on the web I have successfully configured a jail with a VNET interface.. This appears to work as I can ping into and out off the jail from internal and external addresses. For...

Hello folks, yesterday I wrote a Twitter thread to give an example how to deploy VNET jails in a ZFS environment. Here is it again in this forum. A guide to deploy a VNET jail using a FreeBSD 13.0 server with ZFS and populated /usr/src. We start with preparing the file tree. I use /l/prison...

If I want to setup a jail during the freebsd install process, I would have to assign the jail an IP address on the same subnet as the host itself so that I can avoid needing to NAT? Is that correct? Or is there another approach I could use? I'd like to have everything configured during the...

I have an issue forwarding the packets to the cloud from the jail. I have tested Netgraph and epair with the same result. I have enabled nat in sysctl.conf>> net.inet.ip.forwarding=1 I have disabled PF totally and tried with nat enabled nat on $ext_if inet from $jail_if to any -> ($ext_if) In...

So I've been poking at Linux jails in 13.0. I've managed to get a Ubuntu and Debian jail running, but now I want to take it a step further. Has anyone ever got VNET working inside of a Linux jail? I can only get so far before I start running into issues. Anyway, here's my jail.conf path =...

Hi, I'm new to FreeBSD (only started tinkering about with it last week), and after lots of digging through the documentation, handbook, and many other online resources I managed to have my vnet enabled jail working in conjunction with ipfw in-kernel NAT. Both inbound and outbound traffic was...

I know I've started a few threads here about odd networking experiments that I am running in VNET jails. Still haven't figured anything out about those when using epair(4) interfaces. So I thought I'd try a different strategy using VLAN interfaces instead. And this time, include a (janky)...

ok, so I'm about to give up here.. banging my head against the wall the answer is probably obvious, but for a newbie this is... frustrating I've tried to follow a bunch of tutorials but for the life of me, I can't get my jails to reach the internet need some advice This is on a fresh install of...

Hello, I have set up an jail with ezjail while following this handbook tutorial. After setting it up, my physical interface that host uses has two IPs, one for jail one for host. For some programs listening on all IPs in host's interface this is not ideal. Can I add a virtual interface with its...

I'm in the middle of setting up a dedicated server. It's running ESXi and I installed a FreeBSD guest. Using iocage I want to create some jails. I have done this before more than once and usually this is strait-forward... but this time I'm stuck somehow. The jail is created with vnet=on and I...

Hi all, I'm trying to setup a separate subnet for my jails, and I think I have everything setup correctly, but am unsure. Here is the Switch: trunk 45-48 Trk2 LACP vlan 23 name "Jails" tagged 23,Trk1-Trk2 no ip address exit Trunk 1 is the firewall, Trunk 2 is the server. I know my...

I have a vnet jail for my physical NIC. In order to start the pf service in that jail, I had to add a devfs.rule to unhide /dev/pf. I also have wireguard jails which I intend to do the same, and connect them to my NIC-jail. (everything is vnet). Does anyone know if this is a bad idea? Will...

I'm creating a series of network gateway/tunnels with vnet and jails (FreeBSD 12.1p8). The topology looks something like this: NICjail: Contains the physical NIC (igb0), bridge0, and epair members for connection to other tunnel jails (VPNs, Tor, I2P). VPN1jail: Connects to NICjail via epair...

Hello I am currently learning how to use FreeBSD to host some basic services in Jails I am trying to configure networking with jails. I noticed that if I try to connect from a jail to a web server installed on the host, the connection is blocked even if the firewall is disabled. It is a setup...

My setup is as follows: freenas ---- switch ---- station freenas is running FreeBSD 11.2 with iocage jail using VNET/VIMAGE network stack (though same behaviour is observed on warden jails and previous FreeBSD releases) It all started when I noticed that station loses connection to jail...

Starting on p. 165, to create a jail with multiple interfaces, you need to do: create a cloned interface (lo1), specify multiple interfaces for the jail in a comma-separated list, call the jib script with the bridge names, be happy. Step 1: /etc/rc.conf: ifconfig_em0_name="lab"...

Hey all, I follow along in Lucas' new book FreeBSD mastery: Jails. Starting on p. 159, I copied over the /usr/share/examples/jail/jib file and make it executable (something Lucas fails to mention). However, I use a different name for my physical interface: lab instead of jailether...

I decided to share my setup for SLAAC on jail vnet. 1. Create bridge and epair interface in /etc/rc.conf #Configure bridge interface for jails vnet #epair0 - jail interface cloned_interfaces="bridge0 epair0" #create bridge and epair ifconfig_bridge0="ether xx:xx:xx:xx:xx:xx addm re0 SYNCDHCP"...

Would someone please give me a brief explanation of when to use jails with VNET and when not to? If VLAN-ing is not my concern, and services I use do not need a separate network stack - let’s say I run anything from DNS server to MailServer, Database, Java Application Server, VCS, CICD...

Hello all, i have a challenge with the generated mac address on the bridge interface. I am building a host wich serves as base for a number of jails so i am creating a VNET network config, becasue i had to compile the kernel vor VNET support i thought to be wise and created a OVF of the VM...
