Re: [FW-1] The Possible Reasons Why I Telnet Very Slowly from LAN to DMZ through FW-1...
Hello Allen,

AA> Nevertheless, I telnet from LAN to DMZ. It takes almost 2 minutes to show

AA> Can someone tell me what possible reasons it would be?
Your server in the DMZ uses public DNS servers, and tries to resolve
your LAN ip adress (probably part of unroutable IANA private IP space)
(So you probably get two DNS timeouts, or NXDOMAINs.)
Just add your LAN's ip into /etc/hosts on your DMZ server with whatever
name comes to your mind at that time.
PS this has nothing to do with FW1 ;)
