\u015eifreleme, t\u00fcnel u\u00e7lar\u0131 aras\u0131ndaki belirlenmi\u015f trafi\u011fi kapsar. T\u00fcnelden \u00e7\u0131kan ba\u011flant\u0131, ayr\u0131ca TLS gibi uygulama katman\u0131 korumas\u0131 gerektirebilir.

Ofis ve bulut a\u011flar\u0131nda \u00e7ak\u0131\u015fan \u00f6zel adres aral\u0131klar\u0131, t\u00fcnel a\u00e7\u0131k g\u00f6r\u00fcnse bile kaynaklara eri\u015fimi engelleyebilir. Y\u00f6nlendirme, d\u00f6n\u00fc\u015f yolu, DNS \u00e7\u00f6z\u00fcmlemesi ve g\u00fcvenlik duvar\u0131 kurallar\u0131 birlikte d\u00fc\u015f\u00fcn\u00fclmelidir.

MTU ve paket par\u00e7alanmas\u0131 da baz\u0131 uygulamalarda se\u00e7ici eri\u015fim sorunlar\u0131 do\u011furabilir.
