Any advice? Cheers

Just had the same issue, I think it is due to the vnic address attached to the eth0 interface I am declaring as 'NETIF' the function get_nic_subnet_mask returns two subnet masks and the second one added to the command accessing the function gets messed up.
No answer for it yet as I am still a beginner, but it may help you.

I have changed the following in vpn_base.sh to correctly gather the subnet and IP address of a vnic:

function get_nic_ip { ip addr show $1 | grep $1 | grep -Po '(?<= inet )([0-9.]+)' }

function get_nic_subnet_mask { ip addr show $1 | grep $1 | grep -Po '(?<= inet )([0-9.\/]+)' | cut -d "/" -f2 }

I then get completely locked out of the remote machine as all networking is routed elsewhere until I restart. Hopefully you will have more luck.

Sorry for the dead post, but I have encountered the same problem and have found part of the solution... after much trouble shooting, I have gotten rid of the 'integer expression expected' errors. my problem was that for some reason my network adapter has 2 ip addresses assigned to it, so the ip addr show $1 | grep -Po '(?<= inet )([0-9\.]+)' command in the get_nic_ip function shows 2 ip adderesses on 2 lines. This caused the command on line 13 to break. I fixed this by only getting the first ip (changing the command in the function to ip addr show $1 | grep -Po '(?<= inet )([0-9\.]+)' | head -1) My problem now is that the 

Bad argument `24'
Try `iptables -h' or 'iptables --help' for more information.

exception is still coming up. I will update later when/if I fix that.
