![]() ![]() This will present a print out similar to the following: +-+-+-+-+-+ Now to see the status of the newly created jail, execute the following: iocage list More detail on the parameters that can be used to configure a jail on creation can be found in the man page for iocage boot="on": enables the jail to be auto-started at boot time.allow_raw_sockets="1": enables raw sockets, which enables the use of programs such as traceroute and ping within the jail, as well as interactions with various network subsystems.defaultrouter="192.168.0.1": specifies the router for your network, change this as is relevant for you.The selection is arbitrary, though if you’re new to this it’s advisable for simplicity to select something on the same subnet as your router. This should be something convenient to you on the subnet you wish it to be on. ip4_addr="vnet0|192.168.0.9/24": provides the networking specification an IP/mask for the jail, and the interface to use, vnet0.-r 11.2-RELEASE: specifies the release of FreeBSD to be installed in the jail.-n reverse-proxy: gives the jail the name ‘reverse-proxy’.iocage create: calls on the iocage command to create a new iocage jail.To break this down into it’s consituent components: Once you’ve established a SSH connection, you can create the jail as follows: iocage create -n reverse-proxy -r 11.2-RELEASE ip4_addr="vnet0|192.168.0.9/24" defaultrouter="192.168.0.1" vnet="on" allow_raw_sockets="1" boot="on" Refer to the above guide for more detail. Assuming your FreeNAS host is on IP 192.168.0.8: ssh you’re using Windows, you’ll need to use PuTTY or WSL or some other unix emulator. If you’re not sure how to do this, you can follow this guide to set it up. We’re going to run the reverse proxy in its own jail so that it can be managed easily in isolation from other services. Now that we know the problem a reverse proxy solves, lets set one up. This way, all hosts with a subdomain of are covered under the certificate and the SSL configurations can be managed in one place. Instead, I obtain a wildcard certificate (*.) and configure it on the proxy server. I’ve found this immensely useful, as it reduces the management load of configuring SSL for every service that I set up. This means that the reverse proxy handles all of the certificates for the servers it proxies to, instead of each service managing their own certificate. Additionally, this is a good opportunity to introduce SSL termination. This configuration looks like this:Īs you can see, a request to the domain name is made from the internet, this is then forwarded by the router to the reverse proxy server, which determines which server the request is to go to. The reverse proxy is hosted on ports 80 and 443, and it inspects the Host header in each request to determine which service to forward the request on to. It’s not possible to host two services on the same ports directly, and so this is where the reverse proxy comes in. :4343, both will need to be available on ports 80 and 443. Unless I want to specify a port to access at the end of one of these domains, i.e. To illustrate this with a practical example, lets assume that I host two services on my network, and I want both to be externally available at the domains and. So, I guess the first place to start is what is a reverse proxy, and why do you need one? In simplest terms, a reverse proxy is a type of proxy server that retrieves a resource on behalf of a client from one or more services. It’s aimed at beginners, so no prior knowledge of these services will be assumed and every effort will be made to explain what each configuration option does. This guide will present the way I configured this, and attempt to explain some of the design choices along the way. ![]() Recently I decided to make a number of my services externally available, and so the need arose to put a reverse proxy in place to correctly direct queries to the appropriate server. ![]()
