SoftEther Split Tunnelling

I have SoftEther working fine on my home network so I can VPN into it from my iPhone.

My problem is that I currently only have 1mb/S of upload speed on my home internet connect and so if my iPhone does anything else internet related while I am listening I get audio breakup as all traffic is directed through my VPN so it will use some of my precious 1 meg upload.

I have tried disabling everything that might use bandwidth on the phone but still get audio breakup. Probably frequent pushed emails I need to receive etc.

Has anybody got split tunnelling working on softether so you can push a static routing table out when the VPN connection is made. This can then be setup to only allow traffic for my home network over the VPN and all other traffic from my phone will go on it merry way not using the VPN.

I seem to of got as far as you need to enable Virtual NAT  then Secure NAT but there ends my knowledge.

Has anybody set this up or does anybody know if I am in fact trying to do something that is not possible.

Thanks for any help.

    Sorry should of added that setting the iOS option in the VPN settings to "Send all Traffic" to off doesn't appear to do as expected. All the traffic stills goes through the VPN. I think it actually means disable any routing and put all through the VPN when enabled.

    If a set this option and do a speed test the speed test data shouldn't go through VPN but the speed is throttled to < 1 mb/s by my network upload speed. Without VPN speed is 30 mb/s down 15 mb/s up or greater.
