Hi zorz, if I change the server to Router 1 i am successful. Therefore, W5200 seems to operate normally. Check your network configuration between Router1 and Router2. What is the external IP address of Router1 ? Check the external IP address of Router1 whether is same network with Router2 (192.168.3.x) or not. If the external IP address of Router was not sam network with Router2, let me know subnet mask of devices in your network. Thanks,

Hi The routers are checked and work ok … if i change W5200 with a PC i am able to make the connection with the server. This is my configuration on the W5200 HW address : SET Source IP: 192.168.4.3 Subnet mask: 255.255.0.0 Gateway address : 192.168.4.1 Destination IP address 192.168.3.20 Destination port: 2020 ( ports are open on the router and port forwarding enabled too ) Selected TCP when i open the socket ( write 1 to 4001 )it is ok when i start the connection ( write 4 to the 4001 ) than the Socket status register ( 4003 ) goes back to 0…meaning CLOSED Soo, what am i doing wrong ? Is the configuration OK ? regards zorz
