I try to telnet from outside, but there's no response. From internal or my other servers that in one subnet, I get this answer telnet reynaldi.dyndns.org 25 Trying 202.152.21.230... Connected to reynaldi.dyndns.org. Escape character is '^]'. 220 arie.reynaldi.dyndns.org ESMTP Postfix But from other place I got no response telnet reynaldi.dyndns.org 25 Trying 202.152.21.230... telnet: connect to address 202.152.21.230: Connection timed out And in my /var/log/mail, there's no messages that shows any connection from ex. yahoo.com or any other servers. I think it's firewall problem :(

Test it from outside with a

$ telnet yourserver.dyndns.org 25

If you get an answer like:

220 yourserver.dyndns.org ESMTP Postix

it is not a firewall problem. Then you will have to configure postifx correctly.

Hi !

I try to telnet from outside, but there's no response. From internal or my other servers that in one subnet, I get this answer telnet reynaldi.dyndns.org 25 Trying 202.152.21.230... Connected to reynaldi.dyndns.org. Escape character is '^]'. 220 arie.reynaldi.dyndns.org ESMTP Postfix

But from other place I got no response telnet reynaldi.dyndns.org 25 Trying 202.152.21.230... telnet: connect to address 202.152.21.230: Connection timed out

And in my /var/log/mail, there's no messages that shows any connection from ex. yahoo.com or any other servers.

--> I could image two options: 1) your ISP is not forwarding packets to port 25 ==> talk to the tech people of your ISP 2) the packets are blocked by the firewall ==> try to enable logging of all packets in the SuSEfirewall2 script, section 16 FW_LOG_DROP_ALL="yes" Then have a look in /var/log/messages or /var/log/firewall to find out why the packets are dropped.

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 ? regards, On Thursday 05 February 2004 16:53, Togan Muftuoglu wrote:

A wild guess could it be your ISP is blocking port 25

try with logging options set to yes in /etc/sysconfig/SuSEfirewall2 and to test it use "SuSEfirewall2 test" command (warning this is not firewalling all your ports are open it just shows what would SuSEfirewall2 do to the packet )
