I am using Xsocket for Duplex communication between server -client .

Every thing was working fine . my sample can work on different network but i find out the Main issue in Xsocket..

if Client is behind Router , proxy and Fire Wall preventing ICMP traffic Then client Can Not Initiate Connection with Server.

mean those client who can't ping Google . yahoo etc but can access them . those can't initiate connection with server.

Should i've to enable ICMP protocol on client fire Wall ?

I don't know how to handle this issue in my Program .

Can you Help me please ??

Thanks Advance .

  • Please don't Randomly Capitalize words, that's not how English works. If your question is _"When a firewall blocks my traffic, should I let it allow that traffic to let my program function?"_ , the answer is _"yes"_. – CodeCaster Dec 22 '14 at 12:38
  • I'm sorry . well if firewall blocking ICMP protocol then xsocket client not get response from server.. how to handle this issue? – Adam Dec 22 '14 at 13:05
  • By allowing ICMP traffic or choosing another protocol. – CodeCaster Dec 22 '14 at 13:08

Try SignalR or maybe SocketIO and see how they do ?

I talked to the best guy I know in networking and he said that

You should not disable ICMP totally, but instead be very careful if changing ICMP at all. Use WSS (ssl/tls), since routers will let that traffic through Out of scope, but turning ICMP off = "fake security" maybe solve your issue .
