How to change default gateway for Cisco ASA SSL VPN

Ok.

So we have this Cisco ASA 5512 running iOS 9.5 (2) 5. (Yes, shining like new car...). We have deployed SSL VPN using clients and have set up split tunneling.

Everything is fine, except that traffic is routed to another firewall and not our internal router.

VPN clients local home router: 192.168.0.1
Cisco ooold Pix:     10.117.0.1
Ciso ASA 5512  :     10.117.0.3
Internal router:      10.117.0.11 (this is where the traffic should go to)

Route print from a connected client (i've removed localhost and unicast addresses from the list):

Why on earth is the client selecting a random IP (ok, not entirely random IP) instead of - at least - it's own gateway (10.117.0.3)? I've been unable to find a setting in the ASDM for that.

Thanks for any help
