Hi everybody it´s my first post here

I install proxmox and create 2 containers with OpenVZ , in each container use centos 6.3 and install zpanelx in one case and in other ispconfig for try , all ok i use ip forward for redirect by port and access each container

For example for access the container 1 with zpanel put 34.555.44.33:1080 and in the other case the same ip and with different port for access to the other control panel ispconfig , all working over NAT

Ok the problem it´s how i can add domains , because into DNS i ca´nt add port ..... and my problem it´s this if i have different containers and use the same ip how i can manage different OS in each container and for example add domains , etc for each control panel

I read something about reverse proxy and other things but i supose here sure can tell me something more about this

Sure exists the way for redirect to private ip from ip fixed and in this case to container and works all but i don´t know how i can this

Regards and thankñ´s for the help

yes, you can use reverse proxy for http, otherwise get more ip addresses.

for control panels I don't see any problem as long as they are on different ports.
if you want to have same control panel in different CT, just use different port in each CT.

if you want to use http port for all domains you have to use reverse proxy.

do it in one of CT, or create 3'rd CT, install nginx or apache and than in this CT setup proxying.

it's nothing to do with domains, it's about one port (tcp/80).

Yes sorry howewer no understand this and get errors for this things , if i have one domain this domain need DNS and this DNS go to ip , for example 35.345.65.76 it´s my machine´s ip

I can have 2 containers and in each case :

Container 1 :

35.345.65.76:1080

Container 2 :

35.345.65.76:1075

In the machine i install Debian with proxmox and no have any more

In each container i have 2 CP ISPConfig and in each container i have different OS in this case Centos 6.3

When i go add domains in each CP i need add domain and for example add www.mydomain.com ok all well

Now i go to for example name.com and put the ip of my server in this case : 35.345.65.76

The domain try access to ths ip but never load the container where i put or add this domain , it´s this point where i don´t understand how i can redirect the domain in each case to container where i have the CP and until add the domain , because into DNS and A records of domains i can´t put 35.345.65.76:1080 . impossible put port - , etc , it´s this point where i can´t understand if it´s possible appoint domain to container or different containers with the same ip but with other port - port of container - , many people into OVH tell me this it´s impossible and i need ipfailover

I understand sure there is method for when domain go to ip this ip can detect domain and redirect in mode automatic or manual i don´t know but i supose it´s possible because really all containers use NAT and use private IP

Sorry for this long text and thank´s for all possible help at this point i can´t progress , regards

1. there is no possibility in DNS to tell which port to use.
dns name just tells which host to access.
port is what service to access on that host, as example 80/tcp port typically means http service

2. please read my answers. I already told you what to do

3. you can always redirect connection to some port to CT with iptables. than you can access needed service some_domain.com:some_port

4. if you don't understand how things works (dns, services and etc) please read manuals and books. your problem is not related to openvz.

no, you are not right.

dns only tells which host to access. nothing more.
with iptables you create rules only for ip and port. nothing more.
