The dev in responsible for this was going to release an update a few days ago when he noticed a critical bug. I'm not dure when he is hoping to release it now.

FWIW one bug he was going to fix was where there is a space in the endpoint name such as "Hong Kong" and "New York". At the moment you cannot use these endpoints.

Speed should not be an issue unless you have a very fast internet connection. The underlying app is OpenVPN so anything you can achieve with OpenVPN on your server should be possible with ibVPN.

For speed issues, as a lateral jump, what is the output of:

lspci -k | grep Eth -A 3

00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connectio n (Lewisville) (rev 05)

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 P CI Express Gigabit Ethernet Controller (rev 06)
Subsystem: TP-LINK Technologies Co., Ltd. TG-3468 Gigabit PCI Express Ne twork Adapter
Kernel driver in use: r8169
Kernel modules: r8169

You have the infamous RTL8111/8168/8411. Assuming you're on ClearOS 7.4, please can you do a :

yum install kmod-r816*

Then reboot. it should improve you networking performance through that interface.

Under the bonnet, it replaces the r8169 driver with the r8168 driver which is much better sited to your NIC.

I am able to get 1GB speeds at 112MB/sec for read write over the network to shares and my speedtest.net is able to pull down my full internet speeds of 150 down and 20 up.

Its only when I send connections through ibvpn that my speeds slow down to 30 down and 9 up. I applied the update you suggested.

It looks like there is an update available for testing. See here.
