<![CDATA[Connections to DMZ kicking me out]]>Hi

I have a problem between my LAN and my DMZ, when I access the Server via it's private IP using SSH or IMAP/S it works perfectly, but When I switch to public IP from within my LAN (I can't reconfigure Mutt everytime I go in/out of my network so I use my domain name) the server closes the connection after 2/3 seconds whether there's activity or not, for example I login from LAN to DMZ via SSH using public IP (Port 22 already has the NAT forwared to 22 as well as the rule), I will be logged in successfully except after a couple seconds later the connect closes with (connection to example.com closed by remote host!), any idea why this is happening ??

My config.xml

Thx

as seen in the picture Server IP: 192.168.2.2, Laptop ip 192.168.1.2, All traffic from DMZ(192.168.2.1/24) to LAN (192.168.1.1/24) is blocked!

Now If I try SSH or Telnet to any service to example.org (by domain name, so My laptop will get it as 2.0.0.2) the connection will be closed after 3/4 seconds of inactivity! however if i use SSH/Telnet but this time to 192.168.2.2 (by ip) then the connection will stay open…

any solution ??

Thx

Check DNS resolution on the server you are SSH'ing to.  This is common when SSHD cannot resolve the information.

Or turn "UseDns no" on in sshd_config

it didn't work, besides it's not only ssh, imap as well
P.S: the domain name of the router is the same domain name i have, does it matter?
