Hi to everybody, I have a very strange problem here.
One of my client buy a “new” software. The problem is that not work with mikrotik, and wor fine with tplink or linksys.
I make a zoom to the code, And notice that the software login fine into a FTP server, but has error when try to upload.
I ask for the ip/user/pass and test it on Filezilla, this work fine. (ip/user/pass work fine). And why not work the software??
The owner of the software tell me that they use WININET.dll in Visual Prox. For that reason i see that the problem is that library.
I try this software in my home with a mikrotik and have the same problem. If I change the router for a linksys work fine.
In my home I hace a simple connection pppoe and all for default. I run the default script in mikrotik.
by default work fine in RB3011UiAS-RM
by default not work on 3x 951G-2HnD
by defoult work fine in linksys or tplink
why is a user bug? I disable all default rules in “/ip firewall filter”
Only one WAN (pppoe)
/ip firewall nat
add action=masquerade chain=srcnat out-interface-list=WAN
/ip firewall filter
Disable all rule, all work fine except this software and the FTP
