What could be causing this? I don't think it was any settings I made as there was only a couple. Is there some sort of firewall on the box that is killing me maybe?

OpenVPN server drops off the local network
The other day I built an OpenVPN 1.6.1 box using the Virtual Appliance they provide. After a bit of configuring I rebooted the server and noticed I could not log on to the Admin page. I did some digging and found I could not PING that server either. I walked away from it for a day or so and decided I must have done something to cause it. So I decided to start fresh. I blew it away and built a new box but this time I upgraded it to the latest version (1.8.something). All was going smoothly, I made only a couple changes in the admin page and rebooted the server, but then it happened again... After the reboot I found I could not connect to the web page and sure enough, I could not PING the server either. I did another reboot, but this time I set a flood PING to see what it did. I found that it did start to PING as it was starting up, but once it got fully up the PING's stopped...

Re: OpenVPN server drops off the local network
You didn't write about configuration and changes you made. Are you using routing or bridging mode? If the box repond for a time then stops, log in to console and see the logs and start-up scripts.

Re: OpenVPN server drops off the local network
OK....through a series of VM snapshots and roll backs I was able to narrow down to which thing is causing the connectivity lose. It happens when I changed the "Dynamic IP Address Network" setting. I must be reading the verbiage wrong as i am taking it that I need to set it to the network IP/subnet of my internal network (where my DHCP server is located and broadcasting). But once I do that and update the server....poof...off the network it goes. I'm assuming I am miss-configuring it so what do I need to put there? Should I just leave it to the default of 5.5.0.0/20?
Mimiko, to answer your question, it is at the default of Routing.

Re: OpenVPN server drops off the local network
Where/how are you currently changing the IP address of the appliance?

Re: OpenVPN server drops off the local network
This can be done by following instructions on setting a static IP in CentOS (the base OS that the vApp is built on). However, this is not what I am trying to do if that is what you are asking...
