I don’t actually seem to be able to initiate any outgoing connections from your server.
You mentioned that your IP address should be “61.91.6.238”, but what I’m seeing on eth0 is actually “61.91.6.224”. Is that the correct IP address for your server?
Right, I saw the message with the eth0 setting at 61.91.6.224 and thought it was odd.
None of the settings were changed, so after using the site below suggested in the forum to check the settings I see that the network ID is 61.91.6.224.
Looking at your bootup scripts, the one I’m looking at has the correct IP address in it. That may mean that just rebooting may resolve your issue… though that doesn’t explain how it occurred in the first place.
However, you would definitely want your eth0 interface to be the IP address you were assigned, otherwise you might see some unusual behavior.
