This page covers common configuration steps for pfSense CE deployments.
Use the same configuration file referenced in the setup guide for your installation.
pfSense CE is primarily configured via web UI with XML-backed system configuration.
Typical management URL:
https://<pfsense-lan-ip>/
- Interfaces, VLANs, and routing
- Firewall rules and NAT policies
- VPN and remote access settings
- Logging and monitoring options
Recommended initial baseline:
- Configure WAN and LAN interfaces with explicit addressing.
- Keep admin UI and SSH restricted to LAN/management networks.
- Keep default WAN inbound deny policy.
- Configure DNS resolver and NTP servers.
- Create regular encrypted configuration backups.
¶ NAT and Firewall Baseline
- Use explicit firewall rules for LAN egress as needed.
- Keep inbound NAT/port-forward rules minimal and reviewed.
- Prefer aliases for grouped hosts/networks.
- Verify interface assignment after hardware/VM changes.
- Avoid broad
any/any allow rules unless explicitly justified.
- Segment exposed services into dedicated interfaces/VLANs.
- Review package/plugin impact on firewall performance before enabling.
Apply or reload the configuration via the UI or CLI.
Apply pending changes from the UI and confirm service reload status.
Test connectivity and firewall rules to confirm configuration is valid.
Validation checklist:
- Internal clients obtain DHCP and resolve DNS.
- WAN default deny behavior works as expected.
- Port forwards and VPN tunnels behave according to policy.
- Logs show no repeated rule conflicts or interface flaps.
- Audit rule changes with change-control notes.
- Keep backups before and after major upgrade windows.
- Monitor gateway health, packet loss, and rule hit counters.
