Wireshark Capture Interpretation

Hello Experts,

Can someone please take a look at the attached wireshark capture and explain why I'm able to ping my router with ip address192.168.1.2, but unable to ping from the router to my PCwith an ip address of 192.168.1.1?

You will notice that the reply is coming back from 'Loop'. Also can someone explain what the protocol SSDP is? Also why is my interface trying to ping 239.255.255.250?

Cheers

Carlton

Usually routers ping out their WAN interface, not back to the LAN side.

As Qlemo mentioned, pings initiated from your PC will be allowed by your firewall. Pings initiated from your router to your will probably be blocked by your PC's firewall.

Here's some information about SSDP:
