Passive mode FTP works over WAN but not LAN

I'm using pure-ftpd 1.0.46 on Ubuntu 18.04 as the server, with TLS and certificates signed by Let's Encrypt. I have no issues connecting and transferring over WAN. I'm using passive mode, the ports are properly forwarded, and I've configured pure-ftpd to respond with its WAN IP.
However, I can not make a connection over LAN, as it complains about TLS connection termination. I've tried several clients and they all have some kind of timeout error. I suspect part of the problem may be my DNS setup. I have a domain name that points to my WAN, and that is what I usually use to connect to the server. But I have my local DNS server respond with the LAN IP for the ftp machine. So when I'm at home, my laptop makes the ftp connection to 192.168.1.2, but the PASV response is my WAN IP 74.x.x.x. In theory, my router should support NAT loopback, which sends traffic originating in the LAN and destined for the WAN IP back to the local IP to which its forwarded. This seems to work fine for http, and I assumed since the client initiates the passive mode data tcp connection, it should work for that as well. But maybe there's some routing detail I'm missing. Could this be the problem?

Destination IP of data connection does not match peer IP of control connection. Not binding source address of data connection.
That’s pretty definitive. The client is not going to accept a control connection established over a local IP and a data connection over a different IP.
Best solution should be to just change the local DNS to provide the public IP address. Shouldn’t be any harm in that if it works.
At first I thought it might be the client rejecting this particular sort of setup, but I tried several clients and none of those work. They just all time out... I'm trying to avoid doing that DNS setup in general because my router doesn't have enough CPU power to saturate my gigabit ethernet while looping back. So most services route over LAN and I can get the full speed. I don't mind if ftp loops back and is slower since I mainly use smb for file transfers anyways, but I'd like it to at least work...

@Kayson the log of whatever client you listed says the above and it is the client rejecting this setup. It’s probably a security feature. Maybe it can be changed on options in the client. But it’s not going to connect if the two IPs are different as is.

Yeah that does make sense. Thanks. I think I need to set up a different server

This is a terrible solution, but I changed my ftp server to respond to passive requests with the local IP. When accessed over WAN, the filezilla client recognizes the internal IP and ignores it, using the control host IP instead. When accessed over LAN, everything works fine.
