XenServer 6.2 not forwarding ports to VMs

Question

I have a XenServer 6.2 with OVH with 4 additional IP addresses.

For 2 VMs that are installed all is working fine.

I created now a new VM with CentOS 6.6, added the virtual MAC OVH assigned me for the IP and setup the network interface accordingly.

I can connect without problem to SSH on port 22, but all other traffic (like port 80 for apache2) is not reaching the VM.

I already disabled selinux.

Same for example when i switch SSH port from 22 to let's say 51000 it's also not working any more.

What can be the problem with that?

The problem started to appear after i setup a VM with CentOS 7 on this XenServer 6.2.

You need iptables to forward the 22 to some port from host to VM. Me to tried this but fails, finally we own fail-over IP to assign for VMs — Babin Lonston, Dec 13 '14 at 06:05

Problem solved. We had a CentOS Distro where when installing the httpd server it was not automatically adding the rules to the iptables.
