Hello,
since one week I can't find out why will my LVS not work. It's a setup only
for testing:
The LVS setup after boot up:

My tests from the LVS host:
[root@lvs1 ~]# telnet 192.168.13.182 80
Trying 192.168.13.182...
Connected to 192.168.13.182.
Escape character is '^]'.
GET / HTTP/1.0\r\n\r\n
HTTP/1.1 403 Forbidden
Date: Tue, 08 Jul 2014 13:35:01 GMT
Server: Apache/2.2.15 (CentOS)
Accept-Ranges: bytes
Content-Length: 5039
Connection: close
Content-Type: text/html
(.....) This is the CentOS Apache start page
=> the real server is working, tested from the LVS
But this is not working:
[root@lvs1 ~]# telnet 192.168.130.241 80
Trying 192.168.130.241...
telnet: connect to address 192.168.130.241: Connection timed out
The LVS seems not tranfering the traffic to the real server - but I don't
know why.
Can anybody help please?
best regards
Frank
