For your router LAN to be able to route Internet traffic to the VPN tunnel towards the ASA, the crypto ACL needs to be:
On router: 10.14.0.0 0.0.255.255 any
On ASA: any 10.14.0.0 255.255.0.0
On ASA, if you are routing the internet traffic out the outside interface of the ASA, you would need to configure the following:
same-security-traffic permit intra-interface
And because the router LAN 10.14.0.0/16 is private ip address, before being routed towards the Internet on the ASA end, it needs to be PATed to public IP, hence you need to configure:
nat (outside) x 10.14.0.0 255.255.0.0
global (outside) x a.b.c.d
OR/ you can use existing global sequence for example:
nat (outside) 10 10.14.0.0 255.255.0.0
which will use the corresponding global address of 12.69.103.129
Hope that helps.
