[users@httpd] Unable to connect apache server ouside local address

[je...@pcas.com]

Hello 
 
I have an Apache server running several applications. From my subnet I 
have no issu to connect to them (adresse in 192.168.6.).
But from other place (adresse 192.168., like 192.168.1) we are unable to 
connect to these applications. And that occur from only two weeks ! We 
have a redirection to Google (which search adresse of the server)
 
>From these places we are able to ping the server.
With wireshark I see the communication between the client and server (see 
capture in attached file ) line 5 we have the get request and line 6 ACk 
from server:
5  0.468164   192.168.10.113   192.168.6.17     HTTP   361   GET / 
HTTP/1.1  Chat

61228 [SYN, ACK] Seq=0 Ack=1 Win=65535 Len=0 MSS=1460 WS=1 
SACK_PERM=1 Chat
 
Then a new ACK from client line 6, and line 7 the redirection from the 
server :
7   0.693046   192.168.10.113   192.168.6.17     TCP     54     61228 > 
http [ACK] Seq=1 Ack=1 Win=65700 Len=0

302 Found  Chat
But I am unable to understand why I have this 302 redirection.
 
What can I do to identify that behavior ?
 
Thanks your for your help
