-# Ansible Role: gateway
-
-This role configures a Linux host as a gateway,
-routing all traffic from local network clients through.
-
-## Role Variables
-
-- `gateway_enabled`: Boolean flag to enable/disable gateway functionality (default: `false`)
-
-## What This Role Does
-
-When `gateway_enabled` is `true`, the role:
-
-- Sets `net.ipv4.ip_forward=1` and `net.ipv6.conf.all.forwarding=1` in `/etc/sysctl.conf`
-- Creates custom routing table (100) to route traffic through VPN
-- Routes IPv4 and IPv6 traffic from local subnet through VPN interface
-- Allows traffic forwarding and established connections
-
-When `gateway_enabled` is `false`, the role:
-
-- Removes all routing rules and iptables configurations
-- Disables IP forwarding in sysctl configuration
-- Cleans up custom routing tables
-
-## Example Configuration
-
-```yaml
-# In host_vars/rpi5.local.yml
-gateway_enabled: true
-wireguard_autostart_connection: "protonvpn-us1"
-
-# WireGuard connection configuration
-wireguard_connections:
-  protonvpn-us1: |
-    [Interface]
-    PrivateKey = your_private_key_here
-    Address = 10.2.0.2/32
-    DNS = 10.2.0.1
-
-    [Peer]
-    PublicKey = server_public_key
-    AllowedIPs = 0.0.0.0/0, ::/0
-    Endpoint = vpn.example.com:51820
-```
-
-## Client Configuration
-
-For client machines to route through the VPN gateway:
-
-1. **IPv4**: Set gateway to VPN gateway host's IP
-2. **IPv6**: Set IPv6 gateway to VPN gateway host's IPv6 address
-3. **Manual network config**: Disable auto-configuration to use custom gateway
-
-Example client network configuration:
-
-```yaml
-network_ipv4_address: "192.168.1.100"
-network_ipv4_gateway: "192.168.1.254"  # VPN gateway host
-network_ipv6_address: "2001:db8::100/64"
-network_ipv6_gateway: "2001:db8::254"   # VPN gateway host
-```
-
-## Technical Details
-
-### Routing Rules Created
-
-```bash
-# Policy routing rules (priority 200)
-ip rule add iif eth0 table 100 priority 200
-ip -6 rule add iif eth0 table 100 priority 200
-
-# Custom routing table (table 100)
-ip route add default dev wg-connection table 100
-ip -6 route add default dev wg-connection table 100
-```
-
-### iptables Rules Created
-
-```bash
-# IPv4 NAT masquerading
-iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o wg-connection -j MASQUERADE
-
-# IPv4 FORWARD rules
-iptables -A FORWARD -s 192.168.1.0/24 -j ACCEPT
-iptables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
-
-# IPv6 equivalent rules
-ip6tables -t nat -A POSTROUTING -s 2001:db8::/64 -o wg-connection -j MASQUERADE
-ip6tables -A FORWARD -s 2001:db8::/64 -j ACCEPT
-ip6tables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
-```
-
-## Troubleshooting
-
-- **Check VPN connection**: `sudo wg show` should show active connection
-- **Verify routing**: `ip rule show` and `ip route show table 100`
-- **Test connectivity**: `curl ip.me` should show VPN IP from client machines
-- **Check iptables**: `sudo iptables -t nat -L -n -v` should show masquerading rules
