Стефане, това само от wireless устройства ли се случва.
Преди около седмица ми се обадиха с подобен проблем, след упграде до
2.4.26....!!!!!!
Проблема е че устройствата в ЛАН-а нямат проблеми, до като за тези които са
зад АП-та имат пинг до рутера, но рутера не роутва за тях....!!!!
Снощи след като ти постна проблема се зарових в гооглето, но ей богу такъв
проблем никой не репортва (поне аз не открих).
Много е възможно именно в 2.4.26 да е проблема.

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.

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 .
