Unable to connect apache server ouside local address

[jean-marie.schneider@xxxxxxxx]

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
6  0.692928  
192.168.6.17      192.168.10.113 TCP    
 66     http > 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 
8   0.943963  
192.168.6.17      192.168.10.113  HTTP  
341    HTTP/1.1 302 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
