Hi all,
obviously, I am a beginner and I would like to know wath is wrong with my router settings if some programs communicate over internet does not work (When I put the cable directly in my computer, all work fine) ! I tried to make a dstnat to open a port for Bitcomet (P2P download) but it does not work ! Some other programs do the same !
Little help could be very very…very appreciated !
Thanks
Try uploading your config using /export compact so that we can comment.
I did /export compact and I screenshoted it

I would remove all the entries in “/ip firewall nat” and use only this:
/ip firewall nat
add chain=srcnat action=masquerade out-interface=ether1
My clients have no trouble with bittorrent behind my routers, even behind a hotspot. The problem is trying to block them. 
… and make sure that when you follow SurferTim’s suggestion that you don’t just delete the other entries. The current SRC NAT masquerade rule for ether1 is restricted to TCP which is probably where the problems started!
Everything work fine (for the moment :s) ! Thanks a lot guys ! It was the specific protocol in my srcnat ! I just recreate the srcnat without specific protocol and all was fine but I leave my other dstnat and it don’t cause problem !
Again, thanks a lot guys
