Сервер c LInux RedHat Enterprice включен в внутреннюю сеть 172.20.8.0 имеет ip 172.20.8.16
ping 127.0.0.1 не проходит,
также не пингуется ни один из серверов сети 172.20.8.0
также нельзя зайти на этот сервер ни по ssh ни по telnet
failrwall выключен

Ниже приведён конфиг, не подскажите в чём причина.
Заранее большое спасибо.
