A reverse proxy, on the other hand, routes traffic on behalf of multiple servers.Ī reverse proxy effectively serves as a gateway between clients, users, and application servers. For instance, a business may have a proxy that routes and filters employee traffic to the public Internet. The client only communicates directly with the reverse proxy server and it does not know that some other server actually processed its request.Ī traditional forward proxy server allows multiple clients to route traffic to an external network.
A reverse proxy is a server that accepts a request from a client, forwards the request to another one of many other servers, and returns the results from the server that actually processed the request to the client as if the proxy server had processed the request itself.
Unlike a traditional proxy server, which is used to protect clients, a reverse proxy is used to protect servers. What is a reverse proxy? A reverse proxy is a type of proxy server. Proxy servers expose a single interface with which clients interact without having to enforce all of the policies and route management logic within the clients themselves. Systems with shared networks, such as business organizations or data centers, often use proxy servers. By doing so, it can regulate traffic according to preset policies, convert and mask client IP addresses, enforce security protocols, and block unknown traffic. What is a proxy server? A proxy server, sometimes referred to as a forward proxy, is a server that routes traffic between client(s) and another system, usually external to the network. In this post, we’ll dissect the two concepts and explain how administrators can use a reverse proxy for easy access management control. There’s often confusion, however, on how this differs from a reverse proxy. Now just simply map the port 443 in your router to your Synology and you are up and running! Multiple https sites on 1 IP address.Many businesses use proxy servers to route and secure traffic between networks. When imported you need to go to configure and map the right certificate to the correct service. Use the cert.pem and server.key with your intermediate cert to get it imported. Remove the passphrase from the private key openssl rsa -in key.pem -out server.key With the new DSM you can also setup certificates with let’s encrypt! The renewal process will be done automatically every 3 months so no worries on that! Just be sure to put in all SAN domains.Įxport the private key file from the pfx file openssl pkcs12 -in filename.pfx -nocerts -out key.pemĮxport the certificate file from the pfx file openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem if you have your PFX you can convert it with the beneath commands using openssl. Synology expects you to import the certificate with a private key. Next thing you need to do is add the appropriate certificates on the Synology for your https websites. in my case i run my blog, a VMware Horizon environment and a Exchange server. Source is your external url you want the Synology to respond to and destination it the internal IP address of the machine you want to serve. You can either choose http or https as a protocol. In the control panel go to the application portal and click “reverse proxy” So here is how you config a Synology as a reverse proxy.
#SYNOLOGY VPN PLUS REVERSE PROXY SOFTWARE#
Synology build this functionality in it’s NAS software since DSM 6.
Then i found out my Synology NAS can do this also and even stupid simple! Even a nice Kemp loadmaster or F5 load balancer does this trick but then you have to have a big wallet and no wife 🙂īut. So you can set up a small linux machine that runs Nginx or HAProxy and that does the trick just fine for free. While a forward proxy acts as an intermediary for its associated clients to contact any server, a reverse proxy acts as an intermediary for its associated servers to be contacted by any client. These resources are then returned to the client as though they originated from the proxy server itself. In computer networks, a reverse proxy is a type of proxy server that retrieves resources on behalf of a client from one or more servers. This problem can be simply solved by using a reverse proxy. You can run your sites on a different port but that’s just ugly. So for the not so geekies, normally you can only run a single https site on one IP address. Like most people i suffer from the one IP address on your home internet connection syndrome.įor normal people this is not a problem but geeks like us like to run their https sites and then this can be a pain on a single IP Address.
