## About The Project
Microtic compatible Docker image to run Amnezia WG on Microtic routers. As of now, support Arm v7 boards
## About The Project
This is a highly experimental attempt to run [Amnezia-WG](https://github.com/amnezia-vpn/amnezia-wg) on a Microtic router.
### Prerequisites
Follow the [Microtic guidelines](https://help.mikrotik.com/docs/display/ROS/Container) to enable container support.
Install [Docker buildx](https://github.com/docker/buildx) subsystem, make and go.
### Building Docker Image
You may need to initialize submodules
```
git submodule init
git submodule update
```
To build a Docker container for the Microtic run
```
make microtic-arm7
```
This command should cross-compile amnezia-wg locally and then build a docker image for ArmV7 arch.
To export a generated image, use
```
make export-arm7
```
You will get the `microtic-awg-arm7.tar` archive ready to upload to the Microtic router.
### Running locally
Just run `docker compose up`
Make sure to create a `wg` folder with the `wg0.conf` file.
Example `wg0.conf`:
```
[Interface]
PrivateKey = gG...Y3s=
Address = 10.0.0.1/32
ListenPort = 51820
# Jc лучше брать в интервале [3,10], Jmin = 100, Jmax = 1000,
Jc = 3
Jmin = 100
Jmax = 1000
# Parameters below will not work with the existing WireGuarg implementation.
# Use if your peer running Amnesia-WG
# S1 = 324
# S2 = 452
# H1 = 25
# IP masquerading
PreUp = iptables -t nat -A POSTROUTING ! -o %i -j MASQUERADE
# Firewall wg peers from other hosts
PreUp = iptables -A FORWARD -o %i -m state --state ESTABLISHED,RELATED -j ACCEPT
PreUp = iptables -A FORWARD -o %i -j REJECT
# Remote settings for my workstation
[Peer]
PublicKey = wx...U=
AllowedIPs = 10.0.0.2/32
# An IP address to check peer connectivity (specific to this repo)
TestIP = 10.0.0.2
# Your existing Wireguard server
Endpoint=xx.xx.xx.xx:51820
PersistentKeepalive = 25

Usage: $PROGRAM [ up | down | save | strip ] [ CONFIG_FILE | INTERFACE ]
CONFIG_FILE is a configuration file, whose filename is the interface name
followed by \`.conf'. Otherwise, INTERFACE is an interface name, with
configuration found at /etc/wireguard/INTERFACE.conf. It is to be readable
by wg(8)'s \`setconf' sub-command, with the exception of the following additions
to the [Interface] section, which are handled by $PROGRAM:
- Address: may be specified one or more times and contains one or more
IP addresses (with an optional CIDR mask) to be set for the interface.
- DNS: an optional DNS server to use while the device is up.
- MTU: an optional MTU for the interface; if unspecified, auto-calculated.
- Table: an optional routing table to which routes will be added; if
unspecified or \`auto', the default table is used. If \`off', no routes
are added.
- PreUp, PostUp, PreDown, PostDown: script snippets which will be executed
by bash(1) at the corresponding phases of the link, most commonly used
to configure DNS. The string \`%i' is expanded to INTERFACE.
- SaveConfig: if set to \`true', the configuration is saved from the current
state of the interface upon shutdown.
See wg-quick(8) for more info and examples.
