12 – LABORATORIYA ISHI
Dinamik NAT - ro'yxatdan o'tmagan IP manzilni ro'yxatdan o'tgan IP-manzillar guruhiga translatsiya qilishdan iborat. Dinamik NAT ning Statik NAT dan farqi shuki, bu yerda bir nechta xususiy (Private) adresga bir nechta ommaviy (public) adreslar to‘gri keladi. Ushbu holatni amalga oshirish uchun access list va Pool dan foydalanimiz Dinamik NAT bo`yicha ishni bajarish tartibi 12..6 – rasm. Dinamik NAT tamoyili asosida qurilgan tarmoq tuzilishi Birinchi navbatda Router1 va Router2 larga statik ip route beriladi. Chunki internet qismidagi adreslarni oldindan bilmaymiz. Router1(config)#ip route 0.0.0.0 0.0.0.0 12..12..12..2 Router2(config)#ip route 0.0.0.0 0.0.0.0 12..12..12..1 195.158.1.1 dan 195.158.1.10 gacha public IP adreslarni tarqatishimiz uchun TATU nomli Pool yaratamiz. Router(config)#ip nat pool TATU 195.158.1.1 195.158.1.10 netmask 255.255.255.240 LAN tarmoqlar ichida aynan 192.168.1.0/24 tarmoq internetga chiqishi uchun Access list foydalanamiz Router1(config)#access-list 10 permit 192.168.1.0 0.0.0.255 Access list ni TATU nomli yaratilgan NAT ga biriktiramiz. Router1(config)#ip nat inside source list 10 pool TATU Router ning kirish va chiqish portlariga NAT ni biriktiramiz Router1(config)#interface fastEthernet 0/0 Router1(config-if)#ip nat inside Router1(config-if)#exit Router1(config)#interface fastEthernet 0/1 Router1(config-if)#ip nat outside Router1(config-if)#exit 12..7 Rasm. .
