[rhelv6-list] network problem on RHEL6.3

[Tiziana Manfroni]

I do some tests and I have  problems with 192.168.114 private network . 
Infact if I connect from public network (193.204.165.*) or another private 
network (192.168.115.) it's all ok, but for example, if I connect from a 
host with IP address 192.168.114.30 in 'ssh -vvv www at 193.204.165.224' the 
output is "ssh: connect to 193.204.165.224 port 22: no route to host". 
When I connect with 'ssh -vvv www at 192.168.114.60' I see 
"www at 192.168.114.60's password:" I have this network problem for all 
services on server (http, https, mail) and not for only ssh. This server 
worked with RHEL5.8 but after upgrade to RHEL6.3 there is this problem.

Any idea?
