private ip not work with apache

[ramires]

hi
i have a server behind firewall..*(ispcp omega stable 1.0 on debian lenny)

my internal ip 192.x.x.x
my external ip 89.x.x.x

I used 89.x.x.x in Installation process.

when i add a domain to the server all dns and apache real files ip's turn to 89.x.x.x
but i need apache files to be 192.x.x.x becouse of firewall. I have no problem with dns it worked well with 89.x.x.x

Also I changed tpl files
als_entry.tpl:<VirtualHost {ALS_IP}:80>
als_entry.tpl.orj:<VirtualHost {ALS_IP}:80>
dmn_entry.tpl:<VirtualHost {DMN_IP}:80>
dmn_entry.tpl.orj:<VirtualHost {DMN_IP}:80>
ispcp_base.tpl:# httpd [{IP}] virtual host entry BEGIN.
ispcp_base.tpl:# httpd [{IP}] virtual host entry END.
sub_entry.tpl:<VirtualHost {SUB_IP}:80>
sub_entry.tpl.orj:<VirtualHost {SUB_IP}:80>
vh_b.tpl:# httpd [{IP}] virtual host entry BEGIN.
vh_entry.tpl:NameVirtualHost {IP}:80
vh_entry.tpl.orj:NameVirtualHost {IP}:80
vh_e.tpl:# httpd [{IP}] virtual host entry END.

and working file /etc/ispcp/apache/working/ispcp.conf
IP parts to 192.x.x.x but this time gives this error

get_tag() | ERROR: '# httpd [89.x.x.x] virtual host entry BEGIN.
' ne '# httpd [89.x.x.x] virtual host entry END.
', '# httpd [89.x.x.x] virtual host entry BEGIN.
' or '# httpd [89.x.x.x] virtual host entry END.
' missing in src

I try to fix that with perl files but i couldn't find copy part.
if i find that i can easily change real file with sed.
