+\subsection{UDP NAT and Firewall Puncturing in the Wild}
+
+Halkes and Pouwelse~\cite{halkes_udp_2011} measure UDP hole punching
+efficacy on a live P2P network using the Tribler BitTorrent client.
+Their study finds that 79\% of peers are unreachable due to NAT or
+firewall restrictions, yet 64\% reside behind configurations amenable
+to hole punching. Among compatible peers, over 80\% of puncturing
+attempts succeed, establishing hole punching as a practical NAT
+traversal technique. Their timeout measurements further indicate that
+keep-alive messages must be sent at least every 55 seconds to maintain
+open NAT mappings.
+
+These findings directly inform the evaluation criteria for this thesis.
+All mesh VPNs tested rely on UDP hole punching for NAT traversal;
+the 80\% success rate sets a baseline expectation, while the 55-second
+timeout informs analysis of each implementation's keep-alive behavior
+during source code review.
