Unable to ping 1.1.1.1 or 8.8.8.8 or google.com or any other address/IP. Looks like ICMP 8 is blocked by BSNL.

temp-Image-P2-W4-BR.avif

There is no information reg latency/uptime now in unifi because of this.

Code: 
PING 1.1.1.1 (1.1.1.1): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
Request timeout for icmp_seq 4
Request timeout for icmp_seq 5
^C
--- 1.1.1.1 ping statistics ---
7 packets transmitted, 0 packets received, 100.0% packet loss

The PPPOE server mac changed to a Nokia mac address.
 
Runs fine here. Could be temporary due to new BNG and they are setting up things. You still get CGNAT address?

Both v4 and v6 are working fine here in BSNL Pune.
 
probably something related to ipv6 setup they are doing here. This issue started yesterday after a brief outage (they moved to a new PPPOE server). Now this was the log after they moved to new PPPOE server as had ipv6 disabled -
Code: 
pppd: Unsupported protocol 'IPv6 Control Protocol' (0x8057) received

I have enabled ipv6 now and ipv6 is working but ping for ipv4 addresses is failing. traceroute works fine.
 
Then it's their mistake while configuring the new server. The server in my region was also recently changed from Juniper. After the change there was very brief period of no internet occasionally but connection was up each time that happened. Things are fine now. So give it a few days and then if nothing changes submit a complaint.
