Hi Rahul

I determined the following is used:
49.44.59.38 over UDP port 4500.

It looks like AS55836 only accepts UDP connections to those IP addresses and hence TCP pings fails. Any further suggestions?

PS C:\Users\daryl\Desktop\PSTools> ./tcping64.exe -p 4500 49.44.59.38

Probing 49.44.59.38:4500/tcp - No response - time=2010.300ms

Have you tried wireshark? You could inspect each & every packet leaving your network/devices ( and port numbers thereof ).

Hi Rahul

I agree with you and TCP Traceroute/Ping was the first thing on my mind, but unfortunately, I'm unable to determine the port number.

Hi Daryll,

Ping is never the ideal tool to conclude if you're able to reach any given destination. Especially ICMP, this is quite common practice to block ICMP responses. I too am not able to "ping" the same host from AS135817 but Jio VoWIFI works just fine for me.

Maybe you want to do a tcp traceroute on the intended port number ( I'm not sure which port number is being used here for VoWiFi ). You'll surely find more useful information.

Thank you.
Rahul

Hi Folks

Does anybody know who I can reach out to for the following issue?

My freshly allocated prefix (103.176.189.0/24) is unable to communicate with Reliance Jio's VoWiFi end-point on AS55836. And hence my Jio numbers are unable to work with VoWiFi when the source IPv4 address is originating from 103.176.189.0/24.
