[strongSwan] Iphone IPSEC VPN - No traffic being forwarded

[Joshua Paye]

Evening,

I have configured Strongswan to accept connection from the Iphone
ipsec VPN (cisco) client.  However no traffic is being forwarded from
the VPN server to the rest of my network.  Not sure if this is a
strongswan config issue or a linux config issue.  I have IPv4
forwarding enabled on the server.

How do I configure my interfaces and strongswan for traffic to be
routed in the following manner?  I need my client to be able to
connect and access my internal (10.10.10.1/24) network.  Any guidance
would be greatly appreciated.

Setup:
VPN Client
Right Virtual Address: (192.168.10.10)

VPN Server
External: 192.168.1.100/24
Internal: 10.10.10.100/24
Left Virtual Address (192.168.10.100)

Strongswan Configuration:
