SSL VPN not working on iOS but works fine on Windows

So, I've got a SSL VPN set up (on UDP port 443) which is working perfectly on Windows.  I can connect, I get an IP, if I go to Google and type "what's my ip" it shows my home public IP address, all my traffic is routed through the VPN and I can connect to internal DNS names.  However, on iOS I can connect fine and I get an IP but the VPN doesn't actually work.  If I ping an internal IP it doesn't work (internal DNS host names don't resolve either) and if I go to Google and type "what's my IP" it shows the IP of my phones cellphone connection.

Here's the log file from the iOS client:
