Hello, I have a dedicated server which has 5 IP addresses provided.
Sometime back, the serve went offline and I requested the provider to reboot. They rebooted the server. After it came back online, one of the IPs (the main ip) is kind of blocked to outside network, but other IPs allocated for the dedicated work fine.
I shutdown iptables (service iptables stop) and apf (apf --stop) and restarted the network. But still that one IP does not seem to work. And the website hosted on it and SSH through it, does not work.
The technical guy from the service provider is also looking into it. Any help on fixing this would be highly appreciated.
Can you ping that main IP from within the local server?
Have you tried restarting ipaliases if it is cpanel?
Does your route -n look ok?
What ends up fixing it? If it just "randomly" fixes itself sounds like it might be something within the datacenter. One possible way to work around the problem is getting a 6th ip and moving the site to that ip.

Yes, I can ping the main ip from within the server. But I cannot access the outside network within the server coz that being the main IP. Ping requests to google, yahoo and trying to ssh another server with an other provider fails. Tracert to outside network fails at the 2nd hop. It is able to ping its gateway.
looks like you need to contact your provider.
your subnet mask is a 16IP one,
you have only five configured, and looks like the gateway is in the middle of that subnet, so i can only guess what they have configured on thier router / switch acl ...
you ip block should be like this;
Network IP : 188.8.131.52
Broadcast IP : 184.108.40.206
