nfs over floating ip

I am having trouble mounting an nfs share on a VM over its floating
IP. The nfs fileserver is on the same subnet as the floating IP. I
used Fuel to install the cluster, and it is configured with
FlatDHCPManager. I roughly understand that the host is SNATing the
packets from the VM, so maybe the responses from the server are not
finding their way back to the VM?

I assume that your security group rules allow all the standard NFS ports?
111 tcp/udp, 2049 tcp/udp, 4045 tcp/udp

Re: nfs over floating ip [In reply to]

Thanks, Abel. Your response kind of got me looking in the right
direction. I didn't have the security group correct, but more
importantly, the nfs server's iptables were blocking the requests.
Our default rule set would have allowed it, but this server had a
different setup.

Sorry for the noise. All works as expected now.

Thanks,
Chad
