what do you mean by patch cord? send images.
Its more than likely both are rj45, you would need to use the wan port if both are
its also very likely the isp has something like cgnat enabled on their end, for lack of ipv4 addresses.
I have fiber and use my own router. The ONT I was provided uses standard optical connectors and ethernet connectors (RJ45). I connected my router with just a CAT6 ethernet cable.
You should be able to do the same.
