+% ---------------------------------------------------------------------------
+% A basic content slide
+% ---------------------------------------------------------------------------
+
+\begin{frame}{What is IPFire?}
+ IPFire is a hardened, versatile, state-of-the-art Open Source firewall
+ based on Linux. Its ease of use, high performance in any scenario and
+ extensibility make it usable for everyone.
+
+ \bigskip
+
+ \begin{itemize}
+ \item Stateful Packet Inspection (SPI) Firewall
+ \item Intrusion Detection and Prevention
+ \item Web Proxy with Content Filtering
+ \item VPN support (IPsec, OpenVPN, WireGuard)
+ \end{itemize}
+\end{frame}
+
+% ---------------------------------------------------------------------------
+% Two-column layout
+% ---------------------------------------------------------------------------
+
+\begin{frame}{IPFire at a Glance}
+ \begin{columns}[T]
+ \begin{column}{0.48\textwidth}
+ \textbf{Designed for security}
+ \begin{itemize}
+ \item Minimal attack surface
+ \item Regular security updates
+ \item Kernel hardening
+ \end{itemize}
+ \end{column}
+ \begin{column}{0.48\textwidth}
+ \textbf{Community-driven}
+ \begin{itemize}
+ \item Open Source (GPL)
+ \item Active mailing lists \& forums
+ \item \href{https://www.ipfire.org}{ipfire.org}
+ \end{itemize}
+ \end{column}
+ \end{columns}
+\end{frame}
+
+% ---------------------------------------------------------------------------
+% Slide with a block
+% ---------------------------------------------------------------------------
+
+\begin{frame}{Key Principle}
+ \begin{block}{Security by Default}
+ IPFire ships in a secure configuration out of the box. Administrators
+ open only what is explicitly needed — not the other way around.
+ \end{block}
+
+ \bigskip
+
+ \begin{alertblock}{Important}
+ Always keep your IPFire installation up to date to benefit from the
+ latest security patches.
+ \end{alertblock}

+
+\section{Content Examples}
+
+% ---------------------------------------------------------------------------
+% Code listing (minted — requires --shell-escape when building)
+% If you don't want --shell-escape, replace \begin{minted}{bash}
+% with \begin{verbatim} or use the listings package instead.
+% ---------------------------------------------------------------------------
+
+\begin{frame}[fragile]{Checking Firewall Status}
+ You can inspect the active firewall rules from the shell:
+
+ \begin{minted}{bash}
+# List all iptables rules with counters
+iptables -nvL --line-numbers
+
+# Check INPUT chain only
+iptables -nvL INPUT
+
+# Show NAT rules
+iptables -t nat -nvL
+ \end{minted}
+\end{frame}
+
+% ---------------------------------------------------------------------------
+% Overlays / incremental reveal
+% ---------------------------------------------------------------------------
+
+\begin{frame}{How IPFire Handles a Packet}
+ \begin{enumerate}
+ \item<1-> Packet arrives on an interface
+ \item<2-> Connection tracking checks state table
+ \item<3-> Firewall rules evaluated top-to-bottom
+ \item<4-> \alert{Intrusion detection} inspects payload (optional)
+ \item<5-> Packet forwarded, dropped, or rejected
+ \end{enumerate}
+
+ \onslide<5->{%
+ \bigskip
+ \begin{block}{Stateful Inspection}
+ IPFire tracks connection state so return traffic for established
+ connections is allowed automatically — without explicit rules.
+ \end{block}
+ }
