# Re2o firewall with nftables
|
|
|
|
This script creates a firewall from Re2o information using nftables.
|
|
|
|
# What it does :
|
|
|
|
- Fetch mac-ip table from re2o and filter traffic from the adherent NAT with it;
|
|
- Create a NAT table for FedeRez and Adherent, and NAT the admin and prerezotage VLANs properly.
|
|
|
|
# What it does not do (yet) :
|
|
|
|
- Fetch opened ports on Re2o and filter traffic with these infos.
|
|
