Hi folks,
Just came across this thread. The setup of the Xen box here is as
follows;
DomO - a workstation for remote setup/config DomU
DomU1 - mail server for routing (headless)
DomU2 - mail server for domain1 (headless)
DomU3 - mail server for domain2 (headless)
DomU4 - mail server for domain3 (headless)
etc.
Firewall is only running on domU1. I'm running virtual domains, with
all domains pointing at the same public IP (one public IP). All ports
on router are forwarded to the local IP of DomU1. Do I need to have
firewall installed on each DomU? TIA
B.R.
