Нали на втория или третия хост нямаш iptables rule, който да спира трафика към 192.168.1.16/28 например. Защо също така не изпратиш рутинг таблиците на 82.147.151.81 и 82.147.151.68 (всички от /etc/iproute2/rc_tables) - ip route list table local, main, default, etc... Ако те притеснява да изнесеш цялата информация - | grep 192.168.1.
Best e-gards,

Няма филтри. роутинг таблиците са наред . Ето тук е интересното : Рутера
дропва пакетите към 192.168.1.18 , т.е не ги изпраща на eth0 .
