Описываю ситуацию
Есть firewall с iptables, за ним в локальной сети есть pptpd сервер. Снаружи я подключаюсь к нему без проблем, но!!! акромя локальных ip pptpd сервера и локального ip компа я пинговать ничего не могу. firewall для LAN шлюзом не является. Клиент pptp получает ip из диапазона локальной сети. Файрволл на pptpd сервере не запущен. С такими же настройками pptpd сервера всё работает на другом компе, коннекчусь и в LANе как родной.
Но здесь я в LAN не попадаю!
В чем может быть трабл? Почему ppp0 не заворачивает в lAN? С рутингом всё в поряде.
