## Очищаем все цепочки перед применением новых правил
$IPT -F
$IPT -F -t nat
$IPT -F -t mangle
$IPT -X
$IPT -t nat -X
$IPT -t mangle -X

## Блокируем весь трафик, который не соответствует ни одному из правил
$IPT -P INPUT DROP
$IPT -P OUTPUT DROP
$IPT -P FORWARD DROP

## Разрешаем весь трафик в локалхост и локальной сети
$IPT -A INPUT -i lo -j ACCEPT
$IPT -A INPUT -i $LAN1 -j ACCEPT
$IPT -A OUTPUT -o lo -j ACCEPT
$IPT -A OUTPUT -o $LAN1 -j ACCEPT

## Этот блок разрешает icmp-запросы (пинговать сервер) (опционально)
$IPT -A INPUT -p icmp --icmp-type echo-reply -j ACCEPT
$IPT -A INPUT -p icmp --icmp-type destination-unreachable -j ACCEPT
$IPT -A INPUT -p icmp --icmp-type time-exceeded -j ACCEPT
$IPT -A INPUT -p icmp --icmp-type echo-request -j ACCEPT

## Открываем доступ в интернет самому серверу
$IPT -A OUTPUT -o $WAN -j ACCEPT
#$IPT -A INPUT -i $WAN -j ACCEPT

## Разрешаем все установленные соединения и дочерние от них
$IPT -A INPUT -p all -m state --state ESTABLISHED,RELATED -j ACCEPT

$IPT -A FORWARD -i $LAN1 -o $WAN -j ACCEPT

## Запрещаем доступ из интернета в локальную сеть (опционально)

## Чтобы в локальной сети был интернет включаем nat
$IPT -t nat -A POSTROUTING -o $WAN -s $LAN1_IP_RANGE -j MASQUERADE
##Должен быть включен ip forwarding

## Разрешаем ssh (порт 22 - это порт по умолчанию для ssh соединения, если вы его меняли, то обязательно значение 22 надо заменить своим, иначе будет потерян доступ к серверу)
$IPT -A INPUT -i $WAN -p tcp --dport 22 -j ACCEPT

## Перенаправление трафика на сервер JITSI
$IPT -A FORWARD -i $WAN -d $LAN2 -p tcp -m tcp --dport 80 -j ACCEPT
