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 ?
Hi,
I think that TCP server send RST packte to SET.
For more information, Capture network with ‘WireShark’ program(it’s free) in both site(SET site and TCP server site), and post it.
Your configuration is OK.
As you know already, You did confirm it by replacing W5200 SET with a PC.
Once the connection b/w W5200 and PC is successed, The network configuration is correct.
If PC-to-PC test is OK but W5200-to-PC is not OK, it is likely to have problem in W5200.
I guess you mistaked a few in porting or operation in W5200.
Just wont to the say that the problem was resolved …the issue was in Linksys E3200 router … when i removed it …everything is working now … if i will have the time i will try do ckeck the situation and report …
