Help!!! Redirect all DNS queries to go through the router

I have never done very much programming on a router and would like some help please. I would like some help to setup a user script to force dns that I have set on the WAN interface on my merlin Asus rt-ac66r router. I have enabled JFFS partition but have no clue how to proceed to plant this into the router.

iptables -I PREROUTING -t nat -p udp -s `nvram get lan_ipaddr`/`nvram get lan_netmask` ! -d `nvram get lan_ipaddr`/`nvram get lan_netmask` --dport 53 -j DNAT --to-destination `nvram get lan_ipaddr`

On the chance you weren't aware of it, have you checked Merlin's wiki page:

I have looked at the wiki and it says that I need to create a nat-start script. I don't know how to script so I was hoping someone could help me out with this. I also know that I need to telnet or SSH into the router but don't know how to set that up exactly. Any assistance would be great. Thank You.

I'm so sorry. I've been logging in here almost daily yet your last post did not pop up as new (so I didn't know you replied).

I've not messed with scripts yet (tho I've been reading a lot and kinda half-way know where to look. Does this post help you out at all?:
