Karena eth0 & eth1 nya sudah di-layer 2-kan, seharusnya tidak melakukan filter terhadap operasi layer-layer di atasnya.
Setup semua kompie : default gateway 192.168.100.254 (kecuali kompie yg menjadi gw internet) utk bridge : netmask setiap interface dijadikan 255.255.255.255 sebelum di-masuk-an ke bridge ( sebelum addif ) echo 1 > /proc/sys/net/ipv4/ip_forward semoga membantu...
