Port forwarding from Dynamic

RouterOS Beginner Basics
1

I have a router set up with Eth1 set a WAN port with a dynamic IP address. The rest of the unit is bridge and is the LAN side of the router. I am trying to set up a port forward on ETH1 to a specific IP address on the LAN. Basically if anything is coming in the router on port 53 of the public address i need it to go to LAN IP 10.10.10.234. I have found this syntax, but the problem is the IP address changes and I’d rather not have a script on the router.

/ip firewall nat
add action=dst-nat chain=dstnat comment=“” disabled=no
dst-address=<public_ip> dst-port=53 protocol=tcp
to-addresses=<private_ip> to-ports=53


Like I said there is only one WAN port so is there any way to set dst-address to a wildcard or ETH1 instead of a static address?

Thanks,

remove dst-address and use in-interface.

So just to confirm I would need to use this syntax right:

/ip firewall nat
add action=dst-nat chain=dstnat comment=“” disabled=no
in-interface=ether1 dst-port=53 protocol=tcp
to-addresses=<private_ip> to-ports=53

Thank you,
