Dear friends,
saya lagi coba bikin bridge dengan konfigurasi sbb:
br0 (192.168.100.11)
+--------------------------------+ 192.168.100.254
! ! +----------------+
LAN ----//----- eth0 ---+ +- eth1
------------------+ Router +---> Internet
via ! ! Cross
+----------------+
switch +--------------------------------+ Cable
untuk simulasi saya gunakan konfigurasi berikut:
br0 (192.168.100.11)
+--------------------------------+ 192.168.100.254
! ! +----------------+
notebook_a ---- eth0 ---+ +- eth1 ------------------+ notebook_b
cross ! ! Cross +----------------+
cable +--------------------------------+ Cable
command yg saya run:
# ifconfig eth0 0.0.0.0
# ifconfig eth1 0.0.0.0
# brctl addbr br0
# brctl addif br0 eth0
# brctl addif br0 eth0
# ifconfig br0 up
# ifconfig br0 192.168.100.11 netmask 255.255.255.0 up
output ifconfig command:

Hasilnya :
1. notebook_a bisa reply ping dari bridge, begitu juga sebaliknya.
2. notebook_b tidak bisa reply ping dari bridge, begitu juga sebaliknya.
3. notebook_a tidak bisa reply ping dari notebook_b, begitu juga sebaliknya.
pertanyaan:
bagaimana agar hasil no. 2 dan no. 3 tidak terjadi? sehingga dari kedua
notebook bisa saling reply jika dilakukan ping.
thanks in advanced
