Hi All:
I got problem with firewall UDP port 80 and 443. Here is the detail information:
Our company network is use sophos firewall. And our company need to use other company application just like chat tools :skype. the application server is open UDP 80 port to listining the message from client.
1) our application use UDP port 80 and client computer is inside in company. Server is outside and use like AWS cloud server.
2) client send request to server with UDP 80 and then client get response message.
we do the test like
1) we use moble phone wifi network skip company network(skip firewall) program is working well.
2) use company network Server can get message from client but client can not get response from server.
3) if we change the server UDP port from 80 to 82 or 40010 or 8080 it is also work.
Any one face this problem or help me out?
Thank you so much.
