To translate your requirements into a set of firewall rules, we need to clearly define each rule in sequence according to standard firewall management practices. Below is a structured representation of the rules that would typically be implemented in a firewall configuration.
### Firewall Rules
1. **Block Snapgram Traffic**
- **Action**: Block
- **Source**: Internal Network, Sales Network
- **Destination**: Snapgram (specific IP address or domain)
- **Rule**: `deny ip (Internal, Sales) to Snapgram`
2. **Block Traffic from 43.11.x.x**
- **Action**: Block
- **Source**: 43.11.x.x (any IP starting with)
- **Destination**: Internal Network, Sales Network
- **Rule**: `deny ip from 43.11.0.0/16 to (Internal, Sales)`
3. **Allow Connections from Internal to Sales**
- **Action**: Allow
- **Source**: Internal Network
- **Destination**: Sales Network
- **Rule**: `allow ip from Internal to Sales`
4. **Allow Connections from Sales to Internal and Cloud Backup**
- **Action**: Allow
- **Source**: Sales Network
- **Destination**: Internal Network, Cloud Backup Server
- **Rule**: `allow ip from Sales to (Internal, Cloud Backup)`
5. **Block All Other Traffic**
- **Action**: Block
- **Source**: Any
- **Destination**: Any
- **Rule**: `deny ip from any to any`
### Implementation Notes:
- Ensure the rules are applied in the correct order, as firewalls typically process rules from top to bottom. When a match is found, further rules are not checked.
- Adjust the specific IP addresses or network ranges for Internal, Sales, and any specific servers as needed.
- Review logging settings to monitor for any blocked traffic for troubleshooting or further adjustments.
This setup assumes a straightforward firewall that adheres to standard principles. Always ensure to test firewall rules in a safe environment prior to deploying them in a production setting.
