Совет номер один - читать внимательно документацию по TCP/IP. Раздел "маршрутизация".

Совет номер два.
Вероятнее всего на Линухе не настроен шлюз по умолчанию. При запуске pppd укажи опцию defaultroute

Для полной диагностики положи сюды ответы от прог ping IP-адрес, traceroute IP-адрес и route

IP-адрес - это IP компа с которого не работает чего-то.

На компе libra.syunik.am неверно настроен шлюз по умолчанию.
В этом все проблемы.

Внутренняя локалка (сервера syunik.am iz real ipov) идет по маске 255.255.255.240 для линуха был взят один из этих реал IP но в настройке нетмаск стоит 255.255.255.255 .. может проблемма в этом?

Выложи сюда результат команды route с Линуха
И с тех компов.

Думаю тогда разберемся.
