Problem with TCL blocked by firewall!

Hi all.I have this problem some time and i can't solve it.Before i changed my ISP everything was Ok,but now i have new modem/ruter and i forwarded ports but still have a yellow light in Bitcomet and this error about TCP.

TCP Connections:    Established: 8 [MAX:65] / Half-Open: 12 [MAX:65]
LAN IP:    192.168.0.101
WAN IP:   
Listen Port of TCP:    23595 (Blocked by Firewall/Router)
Listen Port of UDP:    23595 (Opened in Firewall/Router)
Windows Firewall:    Added [TCP opened, UDP opened, TCP(ED2K) opened, UDP(ED2K) opened]
UPnP NAT port mapping:    Added

I'm behing two routers adn i use Bitcomet 1.36 because 1.37 doesn't work on WinXP SP2 32-bit.First one (main ADLS router) is TP Link TD-W8951ND and second one is TP Link TL-WR941ND.Internet connection is 17Mb ADSL,antivirus is turned off,only firewall from windows is enabled.
Can you tell me why i got only TCP blocked while UDP is open?Thanks in advance.
