Thanks for your quick response.
My router is having 4 ports.3 are LAN ports and one WAN port.
I connected one PC to the LAN port 1 using an ethernet cable and one PC to WAN port using an ethernet cable.
I assigned a static IP address to PC connected to the WAN port.
Network settings in PC connected to WAN port are the follo.
IP address 192.168.2.235
Subnet mask 255.255.255.0
Default gateway 192.168.2.1
PC connected to the LAN port will get an IP address 192.168.1.33
Router IP address is 192.168.1.1
Ethernet as WAN IP address and remote IP address is 192.168.2.1
Testing Set Up 1:(Sending UDP packets):
Server side(PC connected to LAN port):
i run the application iperf -s -u
Client Side(PC connected to WAN port)
iperf -u -c 192.168.1.33
Result:UDP packets are receiving at the client side.
Testing Set up 2:(For sending TCP packets)
iperf -c 192.168.1.33
TCP packets not receiving at the server side.
When i analysed using ip_conntrack tool connection is establishing but server is sending LAST_ACK.
My aim is to send some TCP packets or video from WAN to LAN.
Any help is appreciated.
