| In the event the OpenVPN gateway VM is inaccessible/locked up/whatever, you can open an SSH tunnel (''ssh -D 9999 $YOURUSER@8.43.84.133'') and set your browser's proxy settings to SOCKS5 localhost:9999 to get at the RHEV web UI. That public IP is on store01 and is a leftover artifact from when store01 ran OpenVPN. | In the event the OpenVPN gateway VM is inaccessible/locked up/whatever, you can open an SSH tunnel (''ssh -D 9999 $YOURUSER@8.43.84.133'') and set your browser's proxy settings to SOCKS5 localhost:9999 to get at the RHEV web UI.
