IPSec on iOS not passing internet traffic

I setup a Barracuda firewall and IPSec VPN for iOS clients to connect via the VPN.  When connected to IPSec, we have did all of the normal tests with DNS, http, https.  The barracuda shows all traffic passing through it.  I don’t know what to do.  We have a packet dump from the barracuda that shows the traffic passing back to the iOS device, so the website should load, but its not.

i am a bit confused as it sounds normal for a VPN client on iOS, without a filtering or blocking. do you have an firewall rules already applied?
