Two RHEL 6 machines with static IP cannot ping each other

  • 772

I am setting up a few servers for a conference at a hotel. They have setup a separate VLAN for me and gave me 3 static IP's and a DHCP pool of 500.

The issue I have is that the two servers can not ping each other.

Server-1 has 192.168.150.2
Server-2 has 192.168.150.3

From both servers I can ping the gateway (at 192.168.150.1) or any computer using DHCP.
A DHCP using computer can ping both servers.

I have been screwing around with the ifcfg-eth0 file lots and trying various things but can not for the life of me figure it out. I'm more of a systems engineer than an admin and not amazing with the IT side. What can I do to trouble shoot this?

  1. Go through the process step-by-step and see where it fails. Does the machine you run ping on get an ARP reply? Does it send the ICMP ping? Does the other machine receive it? Does it send a reply?

    My guess would be that the problem is a software firewall setting in one of the machines.
