I finally found a spare USB stick to try out FTP on my WRTSL54GS, and I've been running into trouble. I'm able to access the share via SMB and FTP locally, but I seem to be unable to access it from outside. I've enabled both the FTP Server and WAN FTP Access radio buttons in Storage/FTP Server configuration, and I've tried changing the port in case 21 was blocked. (Is the FTP Server needed, or is WAN FTP access enough? I don't need local FTP.) I've tried adding the port to the port forwarding rules. (Is that necessary, or is the router smart enough not to block that port?) Does anyone have any suggestions? I'm running "Firmware Version: v2.00.5, HyperWRT + thibor15c+grcore6" Thanks in advance!
