Mm.. I have logged the firewall, here's the messages eb 7 12:07:14 arz kernel: martian source 202.152.xx.xx from 202.59.161xx, on dev eth1 Feb 7 12:07:14 arz kernel: ll header: 00:60:97:63:2c:13:00:0d:28:c7:ae:74:08:00 It happend when I try access ssh from external IP. 202.152.xx.xx is my IP. Any suggestion ? Is it why my server can't be access from outside ?

--> Yes. It means that there is something wrong with the netmask and subnet settings of your configuration. Could you list the settings for IP, gateway, netmask for all your interfaces eth0, eth1, ... I guess the netmask is not 255.255.255.255 as it should be but more like 255.255.0.0 Tell us more about your setup and we may be able to help you.
