      "abstract": "Keamanan jaringan menjadi aspek penting dalam menjaga integritas dan\r\nkerahasiaan data di tengah meningkatnya penggunaan teknologi digital. Salah satu\r\npermasalahan yang sering terjadi adalah keterbukaan alamat IP internal terhadap akses\r\ndari jaringan eksternal, yang berpotensi dimanfaatkan oleh pihak tidak bertanggung\r\njawab untuk melakukan serangan. Kondisi ini dapat menyebabkan kebocoran alamat IP\r\ninternal, gangguan konektivitas, serta menurunkan tingkat keamanan sistem jaringan.\r\nOleh karena itu, diperlukan mekanisme yang mampu melindungi jaringan internal tanpa\r\nmenghambat proses komunikasi data antarperangkat.\r\nPenelitian ini menggunakan metode deskriptif kualitatif dengan pendekatan\r\nsimulasi jaringan menggunakan Cisco Packet Tracer. Proses penelitian dilakukan dengan\r\nmerancang topologi jaringan dan mengimplementasikan tiga skenario, yaitu Static NAT,\r\nDynamic NAT, dan tanpa NAT sebagai pembanding. Pengujian dilakukan melalui uji\r\nkonektivitas menggunakan ping, trace route, dan akses web server, serta uji keamanan\r\nmelalui analisis translasi alamat, filtering, dan packet capture. Data yang diperoleh\r\nkemudian dianalisis secara komparatif untuk mengetahui perbedaan kinerja dan tingkat\r\nkeamanan dari masing-masing skenario.\r\nHasil penelitian menunjukkan bahwa penerapan NAT, baik Static NAT maupun\r\nDynamic NAT, mampu meningkatkan keamanan jaringan dengan menyembunyikan\r\nalamat IP internal dan membatasi akses langsung dari jaringan eksternal. Static NAT\r\nmemberikan tingkat stabilitas terbaik berdasarkan nilai delay dan jitter, sementara\r\nDynamic NAT menawarkan fleksibilitas dalam penggunaan alamat IP publik.\r\nSebaliknya, tanpa NAT menunjukkan tingkat keamanan yang rendah karena alamat IP\r\ninternal terekspos. Penelitian ini dapat dimanfaatkan oleh mahasiswa, teknisi jaringan,\r\ndan pengelola sistem sebagai referensi dalam menerapkan NAT untuk meningkatkan\r\nkeamanan jaringan. Penelitian selanjutnya disarankan untuk menguji NAT pada skala\r\njaringan yang lebih besar atau dikombinasikan dengan mekanisme keamanan lain.",
