Cannot browse WEB but can browse LAN

[Franchino]

Greetings,
I set up an OpenVPN server on my DD-WRT flashed Netgear R8000 router. Using the OpenVPN Windows client everything is working fine, I can connect to it, browse (server) local LAN and navigate on Internet. Using the iOS client I am able to connect and browse the local NET but cannot navigate on Internet. Any idea of why is it happening?

This is the client log content:

and the client config:

cipher AES-256-CBC
ca ca.crt
cert iphone.crt
key iphone.key
auth SHA512
remote-cert-tls server
comp-lzo
tls-auth tlsauth.key 1

the settings on the iOS and Windows client are the same (except for the cert and key option that are specific ofc)

Any help would be greatly appreciated
