I'm running VMware Kerio webserver Virtual Appliance (CentOS).
On CentOS everything working just fine . Having the problem to connect Kerio over webmail on the local net .

1)Telnet <mailserver IP> 110 , 25
on host PC ( windows XP ) does not returning anything.
2)Ping <mailserver IP> -
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
( from host PC to CentOS and back OK no problem)
3)firewall everything open one way and other way.
4)telnet from host PC and CentOS (pop3, SMTP) to ISP and remote mail box no problem.

Thank you in advance.

Then trying to find out which ports open:
Nmap scan report for <mailserver IP>
Host is up (0.00s latency).
Not shown: 88 filtered ports
22/tcp open ssh
25/tcp open smtp
80/tcp open http
110/tcp open pop3
119/tcp open nntp
143/tcp open imap
389/tcp open ldap
443/tcp open https
465/tcp open smtps
631/tcp closed ipp
993/tcp open imaps
995/tcp open pop3s

Hi Alex,
the two things necessary to make the Kerio VM work are:

Please have a look at: -static-ip-address-on-centos-linux.html

Two steps are necessary to make the server work:

1. Configuring the network:
should do the trick. I did the configuration not in the graphical interface, but on the command line. The necessary static information I did get from my hoster.

After that one, the server should be already pingable, but you should not get any website to load in the included Firefox.

2. Setting up correct DNS Servers:
This step is also described in the tutorial. /etc/resolv.conf is the place to go.
It might be, that you should't edit that file directly, but use the network manager you should find in the menu. I used the Google DNS Servers: and for that step.

Restart the server and everything should work.

In YOUR post, you MIXED two methods, that do not fit together. If you have set your VM as "bridged", that is all you have to do. You have your VM DIRECTLY on the net, without ANY adaptation of the host OS necessary.

With some providers, this however is not possible (they only allow one MAC/host IP). In this case, you would have to setup the VM in "NAT" mode and THEN (and only then) you would have to setup port forwarding.

Once again: the ONLY thing necessary on a "bridged" VM is the correct network configuration!! No forwarding!

Hope this helps. Maybe this answer would have helped other people as well? A public post would have made sense, possibly.

Hello Thunda.
I didn't check all options , but at first sight , NAT stoped my telnet to SMTP and POP3 .
Fine, better start by numbers:

1. configuration I have :
Guest OS (CentOS + Kerio) -> Host OS( Win XP) -> DC (W2K3 ) ->Router->ISP->MailBox (

2. Guest OS ( Static IP[] + NAT ) -> Host OS (Static IP[ + Firewall ) -> DC (IP[] DNS [], DHCP , Firewall) -> Router ( Static IP = Gateway [] , Firewall)

in this configuration I have NAT running on another Guest OS (W2K3) but there were no problems at all since it never been used for local access over https or http , so I did try telnet to this GuesOs as well but same result telnet hungs up.

That's it for the moment.
Going to check other options .
