# gre-on-wg
|
|
|
|
Create a GRETAP mesh network on top of wireguard.
|
|
|
|
## Usage
|
|
|
|
`gre-on-wg WG_QUICK_CONFIG_FILE ADDRESS_TRANSLATIONS`
|
|
|
|
The first argument is the path to a wg-quick config file, while the
|
|
second argument provides address translations for wireguard internal ip
|
|
addresses to the new addresses.
|
|
|
|
The wireguard configuration must have the `Address` config in the
|
|
`[Interface]` section set to exactly **one** address, similarly every
|
|
`[Peer]` section may only contain **one** AllowedIPs entry with **one**
|
|
addresss.
|
|
|
|
The translation file should contain lines of the following format:
|
|
`<wireguard private ip> <space> <new bridge network ip>`
|
|
|
|
### Example
|
|
|
|
Consider the following wg0.conf file
|
|
|
|
```
|
|
[Interface]
|
|
Address = 192.168.3.100/24
|
|
|
|
[Peer]
|
|
AllowedIPs = 192.168.3.101/32
|
|
|
|
[Peer]
|
|
AllowedIPs = 192.168.3.102/32
|
|
|
|
[Peer]
|
|
AllowedIPs = 192.168.3.103/32
|
|
```
|
|
|
|
And the following translation file
|
|
|
|
```
|
|
192.168.3.100/24 192.168.4.100/24
|
|
192.168.3.101/24 192.168.4.101/24
|
|
192.168.3.102/24 192.168.4.102/24
|
|
192.168.3.103/24 192.168.4.103/24
|
|
```
|
|
|
|
This would result in the creation of the bridge network `wg0br1` on host
|
|
`192.168.3.100` where the different peers have the addresses
|
|
`192.168.4.10[0123]`. Additionally the point-to-point networks
|
|
`wg0gre[1234]` would be created.
