Hi,

I can reach internal to dmz and dmz to internet and I can reach to fw
external interface from internet and vice versa, but of course I cannot
reach dmz from internet (it means expecting to reach 10.0.0.10 from
internet)

The rouing table looks like

1.2.3.192 0.0.0.0 255.255.255.192 U eth0 #
ext interface with real IP (eth0:1.2.3.194)
10.0.0.0 0.0.0.0 255.255.255.0 U eth1 #
dmz (eth1:10.0.0.1)
192.168.1.0 0.0.0.0 255.255.255.0 U eth2 #
internal LAN (eth2:192.168.1.1)
0.0.0.0 1.2.3.193 0.0.0.0 UG eth0
# default GW (router)

I have a feeling that I'm missing smthg here.

Regards,
Oyku
