I have a problem with RV-042 (126.96.36.199 firmware) router. There is a FTP server behind the router. I've set up port forwarding and noticed a strange problem accessing it from Internet. I have two ISPs (WAN1 is faster 2048/2048, WAN2 is 128/1024). If I choose "Smart Link Backup" FTP works with selected WAN without any problem. If I use "Load balance" and set "Max. Bandwidth provided by ISP" to above parameters I can FTP via WAN1. If I try lo login via WAN2 ftp client logs in, but after "dir" stops with "Can't open data connection". If I reverse bandwidth parameters (cheating a little ;-)) I get this problem on WAN1 (and WAN2 works well). I tested both passive and active FTP mode - no effect. Any suggestions ?
