Host WCF Service on Public Ip

Question

I have created a WCF service on my local and host the service on IIS so that I can invoke my WCF service from other PC. Both PCs are under the same router. I am able to call WCF service on my local but not able to browse the same service from other PC.

I google this issue and found many similar issues but not able to understand the resolution of mine. One thread I found little helpful but still not able to get it.

My service host on 192.168.X.XXX:82 , when I browse the same on other PC it shows "Network Issue". Please help me to get out from this.

Answer 1

I have added an Inbound and Outbound Rules on my system and allow Port 82 for "Domain, Private and Public". You can set the Rules " Control Panel-->All Control Panel Items->Windows Firewall-->Advance Settings ".

Hope this helps to someone.
