Mam takie dwa pytanka odnosnie konfiguracji Cisco Pix. Po jednej stronie jest PIX a po drugiej jest ASA. Skonfigurowalem tego PIX aby zadzialal S2S VPN i o dziwo zadzialalo za pierwszym razem
(strasznie sie zdziwilem). Jednakze chcialbym spytac o:1. ustawienia DNS - w konfiguracji ponizej ustawilem adres DNS servera po drugiej stronie VPN a moze powinienem ustawic to na adres routera do ktorego jest podlaczony ten PIX?
2. Czy ta konfiguracja jest poprawna? Jakby ktos zauwazyl jakies bledy, szczegolnie jesli chodzi o bezpieczenstwo to bardzo bym prosil o komentarz.
Za wszelka pomoc serdecznie dziekuje. Ponizej wklejam configa.
