ER-X Load Balance Port Forwarding

[DocUmibozu]

Hello,
at home I have an fttc 60/20 mb connection that is stable and reliable.
My ISP recently gave me a free LTE SIM with unlimited data cap and with it I can obtain a 100/30 mb connection after dinner and in the weekends (when internet is used the most at my home).
I decided to try load balance and a friend of mine offered to give me an edgerouter ER-X to try.
Now I use an asus router with merlin firmware, on which I run an OpenVPN server that needs to be online on the most stable connection (the fttc one).
I'd like to put the ER-X between the ISP modems and the Asus-Merlin, which will continue to serve my lan.
I'm a novice on ER-X and, before embarking on the journey of configuring it, I've a question to this group gurus: it's possibile to instruct the ER-X to forward the Openvpn listening port (1197 in my case) to only the fttc lan so to block access to the LTE connection?

I'm not sure what it runs for an os but, you should be able to put a static route with the port or an iptables entry for traffic destined and from that port.

I read some howto and it seems to be based on linux

Linux makes it easier then.

Looking at what @Tech9 posted though it feels more like something else like a hybrid of Cisco/juniper commands.

EdgeOS. Some GUI, some CLI.

You can place your Asus router's WAN IP in DMZ and save individual port forwarding.
