Є виділений сервер Hetzner з одним інтерфейсом та 3 додаткові IP адреси. На сервері встановлено Proxmox з віртуальними машинами. На одній віртуальній машині встановлено pfSense (Virtual Machines), який виступає в якості шлюзу. Через нього проходить трафік до інших віртуальних машин. Дві віртуальні машини (на Linux Container) використовують виділені IP, інші користуються IP адресою машини, на якій встановлено pfSense. Необхідно запропонувати найбільш продуктивну схему роботи мережі та налаштувати її. Зараз на сервері Proxmox налаштовано vmbr0 (із зовнішнім IP) на enp4s0 та vmbr1 (локальна мережа ). В результаті повинно бути: 1) дві віртуальні машини використовували власну IP (для вихідного та вхідного трафіку). Це веб-сервери, на яких розміщуються сайти; 2) інші віртуальні машини
