Setting up your own cloud instance (relay server).

Hi Everyone,

We are almost ready with the advanced admin panel where you will be able to access advanced functions and features of your Remotly account (like setting up the IP address and port of you own data transfer server).

Why is this so important? It is very important not to open your main PC to any potential external attacks. Port forwarding is a nice feature but it is also a security threat. Furthermore if you leave your computer on all the time it consumes much more power than a simple Linux server based on a low-power device like Raspberry Pi or similar device.

Below are some of the main benefits of setting up a private connection server either at home or in your company:
- Lowest possible network lag
- No need to port forward data to any of your PCs that you want to access remotely
- Less power consumption
- Wake-On-Lan accessible from WAN (outside your local network)
- Attacks can only be done on the Linux server. But this does nothing for the attacker as all the data passing the server is encrypted with a key that is not accessible by this server
- Share your server with your friends/co-workers (limit costs)
- No problems with GDPR (passing sensitive data via third party servers)

This guide assumes you have already set up the remote computer (Linux server, Raspberry Pi etc.) you want to make your relay server and have all necessary permissions.

1. First, we need to access the remote machine's Linux system using SSH client. To establish SSH connection, client will ask to provide host IP address and user credentials. There are various tools you can use at this point, e.g. WinSCP, FileZilla or build-in openssh. From now on all the subsequent steps will refer to the server operating system.

2. In order to download Remotly relay you can use WGET utility typing the following command:
wget https://downloads.mirillis.com/files/beta/remotly-relay.zip

3. After that, unzip the remotly.zip file
unzip remotly-relay.zip
If you don't have unzip installed you probably run into "unzip: command not found" error. In that case you can install it by running the following commands:
sudo apt-get update
sudo apt-get install unzip

4. Grant proper credentials:
sudo chmod 755 -R remotly
sudo chown root:root -R remotly

5. Move all files to destination location:
sudo mv remotly /srv

6. Open the configuration file and set desired port number substituting the sample one. If it is possible, we recommend to use the standard HTTPS port (443) to avoid future access problems.
nano /srv/remotly/config/remotly-relay.json

7. Execute the installation script:
sudo bash /srv/remotly/script/installremotlyrelay.sh

8. Start the service:
sudo bash /srv/remotly/script/startremotlyrelay.sh

9. Double check if Remotly Relay service is running:
systemctl list-units --type=service --state=running
There should be remotly-relay.service on the list

Now that your server is running all we need to do is add your private server's IP and port(s) in your admin panel:

That's it! Now all your Connect Anywhere connections will use your own server.

If you have any questions please comment under this post.

Hi Herman. Yes, there will be a separate version of this feature for free/home use. There will be even a version for Windows soon. Although the enterprise version is much more advanced and allows to use multiple relays selected dynamically. We will let you know as soon as these functions go live.

Can we be notified when there is progress made, or should we check the forums regularly?

Hello ZaInT,

To speed things up we will first upload a pre-release version of private relays (binaries for Windows and Linux).
After setting your server you will need to create a relayinfo.txt file with IP:pORT.
We will post details soon + a link to a test version (v1.14.0).

In the final version private relay setup will be done in the UI but this is still not completed (everything else is ready).

BTW. If you have a good internet connection then you can share this file with your friends so that they can use your relay too :)
BTW2. We are going to roll out 2-3 updates in the next 2 weeks that will close 1.x phase version of Remotly for PC and Android.

Awesome! Thank you for the fast answer :)
Will deploy on a Debian VPS and see how it goes but I'm optimistic.

After an internal meeting we have decided to unlock "custom relays" option for all users (with some limitations comparing to commercial/enterprise versions).

All our current relays run on Debian/Ubuntu (most on Debian) so we are sure everyone will be happy with the performance when running a relay close to their location. If someone will like to share their relay with others they only need to know the IP and port and enter it in the admin panel (we strongly recommend using 443 port as this passes HW firewalls well).

The initial versions will be for x86/x64 platform with ARM version scheduled later.

After passing government grade tests/certifications the relay code will eventually become open source so that everyone will be able to build it for any platform.

We will inform next week when everything is ready to go public.

Next Monday we will upgrade the admin panel to show custom relays option for everyone. We advise to start the docker (which is already deployed and a tutorial will be also ready on Monday) on 3 different ports at the same time: 443, 80, 5938. After adding a relay server using the admin panel WITHOUT any port (just IP) Remotly will assume that the relay might work on one of the 3 ports. If port is added to the IP only this port will be used.

Why we are adding 3 ports working in parallel? The answer is aggressive HW firewalls (like Fortigate) that filter out traffic in government offices etc. After starting an unlogged Remotly server on PC (either QuickSupport or full version) we first analyze which port will work and provide this port to the clients that connect to use it as a preferred one.

BTW. The docker is placed on the official docker repository and has been tested on Debian.

THANK YOU, I run a whitelist for specific IPs on 80 and 443 and everything else goes to a honeypot to waste resources for bots and script kiddies - but my work only allows connections to like a handful of ports so that is PERFECT! If you want suggestions for other ports I would say 587, 993, 995 and maybe 22.

Though, will you only release the Docker image at that time? Nothing for bare metal?

Hi ZaInT, of course bare metal will stay :) The tutorial for bare metal that is at the beginning of this thread will be still valid. The main relay binary is the same as in the docker. It just needs a few tweaks and a link to the sever download.

Yes! We are sorry for the delay:

Please find a short tutorial regarding custom relay setup below. It is not possible to use it until the admin page is updated (this will be done tomorrow) + updates on PC and Android are needed (v1.14.0 for PC and Android v1.33 - these will also be ready tomorrow).

After installing docker on your system please execute:

docker pull mirillis/remotly-relay:latest
to download image of remotly-relay, then run image in container:
docker run -dp [Public IP]:[Port]:443 mirillis/remotly-relay
Where [Public IP] is public ip address of machine where container runs and [Port] is port on machine
where remotly-relay should listen on. To avoid problems with ports blocked by firewall it should
be set to 443 by default.

So if you want the relay to be working on 3 ports at the same time:
docker run -dp [Public IP]:443:443 mirillis/remotly-relay
docker run -dp [Public IP]:80:443 mirillis/remotly-relay
docker run -dp [Public IP]:5938:443 mirillis/remotly-relay

Please let us know in case of questions.

Ok... Dockers are horrible at networking. We are seeing much more stuttering on our production relays. We are going to revert everything tomorrow :/

Our relays have been reverted to bare metal mode. The zip with the binaries will be available for download in the admin panel soon (remotly.com and state servers will be updated in the next few hours).

Updated admin panel is now available. You should see 2-step verification to your admin panel from this update.

Remotly v1.14.0 for PC is now available. Changelog for this update will be available soon.
