Can't connect to Alfresco

I have installed Alfresco 5.0 on VM (Centos) in our company. Alfresco logs look fine and Alfresco is working. But if I try to call Alfresco-Website from my Windows Office PC, I won't be able to connect to it. I call the site http: // IP-Address: 8080 / share At first I thought the firewall was blocking port 8080. Other web applications like Joomla or Moodle, which also run on Centos-VM, are accessible over the Internet without problems. I am stuck here and would appreciate any help. Below are the results from netstat, iptables and nmap:

It seems to be listening on port 8080:

netstat -an | grep 8080 | grep -i listen
tcp 0 0 :::8080 :::* LISTEN

      

        
        
        
      

    

Here's the iptables output:

iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT icmp -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere tcp dpt:http
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:mysql

Chain FORWARD (policy ACCEPT)
target prot opt source destination
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
