Hello I have checked for details but didn't get the luck. My destination host does have the rules: REJECT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:993 reject-with tcp-reset REJECT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:143 reject-with tcp-reset REJECT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:587 reject-with tcp-reset And I telnet from two different DCs (one is Dallas, another is LA), both got timeout, rather than the expected disconnection quickly. $ telnet 193.106.250.86 587 Trying 193.106.250.86... telnet: Unable to connect to remote host: Connection timed out If I clean iptables in the destination host, this telnet will get success at once. Any hints? Thanks. -- sent from https://dkinbox.com/
