They are NOT taken. Both ports have been forwarded to the local IP
of
the routing server under testing.
Hi Stephen,
the forwarding sounds like it might be the cause of the problem,
though I must confess that I am not sure. How is the forwarding
being done?
Hi Simon,
This is a Xen Box, a Virtual Machine
Host - Debien Etch workstation, local_IP 192.168.0.110
Guest1 - routing mail server, local_IP 192.168.0.213
Guest2 - mail server, local_IP 192.168.0.208, domain1
Guest3 - mail server, local_IP 192.168.0.209, domain2
Guest4 - mail server, local_IP 192.168.0.210, domain3
On router all ports are forwarded to 192.168.0.213, the routing mail
server.
Example;
Service Ports Server IP
143 192.168.0.213
993 192.168.0.213
etc.
Mail clients connected to local network can find their own mail server
sending/receiving mails without problem. All incoming mails are
pointing to the same public IP and delivered to their own mail servers
by the routing mail server according to domains.
B.R.
