So here's the prob:

I used to DCC Send with no problems. Well, suddenly I couldnt send files anymore. And this didnt happen after a reboot or a system config change, NO, it happened right after I sent a file, without changing ANY crap on the computer.
Since 2 weeks, everytime I try to send a file, the destination sees "failed to connect" and the send doesn't start.
I have a Draytek 2600 Vigor router, but that's not the problem sice with NO port forwarding I used to send files and from the other PC i send files with problems.
There's no ip mismatch, no firewall, no anything. What can I do? Thanks a lot smile
