change ip/ dual IP when ispCP behind nat

[bitte]

Hello Forum,

if I have following Setup:

ispCP Server has internal IP-Address (e.g. 192.168.0.200) and I have this IP-Address natted from outside (public IP Address e.g. 141.14.120.200), and I want the customer use its own DNS Entries or Website I configured ispCP to listen on both IP Addresses.

Code:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 00:aa:aa:aa:aa:c3 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.200/24 brd 192.168.0.255 scope global eth0
    inet 141.14.120.200/32 brd 141.14.120.255 scope global eth0:2
       valid_lft forever preferred_lft forever

But unfortuenately, this does not work for the apache, which answers
from outside with the admin website.
when using from inside the customer's website exists.

So - what to do to get a system setup to hide internal ip-addresses and use the external/public one.
If setup ispcp i need to give the system the internal ip address.

Best regards.

Best might be, if vhost entries might be created both for the internal and the external IP Address. Is this possible? Currently there is only one IP Address configured for a domain, even if i have a reseller who provides both external and internal IP.
