pfSense NAT forwarding simply doesn't work

I've followed the short docs on pfSense's website on how to do this but it isn't working. I have an FTP server running vsftpd sitting behind my pfsense firewall. I have a regular router between me and the internet, and pfsense is just another computer on my network. Behind pfsense is a switch, with multiple vlans configured, and the FTP server is running on one of these vlans connected to the switch.

So basically what I am trying to do is configure port forwarding so that when I do
ftp (pfsense_ip) 13421
It forwards traffic to the FTP server on port 21. I've created a NAT forwarding rule from the pfsense IP and port 13421 to the FTP server IP and port 21. I've created a WAN rule to allow traffic on port 13421 through. I've enabled NAT reflection. I've restarted pfsense half a dozen times. Not only can I not connect, but no matter what rules I create on the WAN interface, nothing seems to change. If I create a WAN rule for port 22, then scan with nmap, it shows that port 22 is filtered still.

So in short, it appears as though the firewall is literally ignoring everything I tell it to do. I'm sorry I am asking this here instead of pfsense's website, but they are largely inactive. Thanks.

Just off the top of my head, is your switch 'vlan' aware ?

BTW their forum is not inactive...

It is certainly vlan aware. Part of the strangeness is that this exact same(I thought) set up worked awhile ago, the only difference being that it was for port 22 instead of 21. I apologize, I realize that it will be hard for people to help me without knowing more information. Information which would be hard to convey over the internet. I suppose I should figure it out on my own. Mods feel free to delete this thread.

Again I apologize.

Is the port being blocked from your ISP, or any device prior? Does wireshark show any traffic on those ports?
