Heritage from m0n0wall

t1n1wall inherits architectural ideas and operational patterns from m0n0wall lineage.

What carries over

• Interface assignment and segmentation fundamentals
• Stateful firewall and NAT reasoning
• Console-first recovery model for network appliances

What does not carry over directly

Historical content may include references that are no longer appropriate for current operations.

Terminology adaptation

• ipfilter / ipf in older material -> use pf terminology and workflows in t1n1wall docs.

Legacy technology notes

• Browser plugin-era instructions (for example, old SVG viewer guidance) are obsolete and intentionally excluded.
• PPTP appears in historical docs but is legacy-only and not recommended for modern high-security deployments.
