Thanks to network admins at Bharti and Hurricane Electric, RTT to HE’s IPv6 tunnel server at HK PoP is reduced. Yippee!!

I’m glad you have found the better routing to the Hurricane Electric Hong Kong POP from your Bharti Airtel connection. In general we try to constantly improve peering and global routing as part of our day-to-day operations. In this case your IPv6 tunnelbroker connection is the winner.
Enjoy your faster IPv6 connection.
Hi Martin,
Thanks for the comment
.
Looking forward to see latency reduced even more or better ISPs offering native IPv6 connectivity in India.
Thanks
Hey Ashish,
I just wanted to know how you set up the tunnel? When I tried setting up the tunnelbroker from HE, it said that the firewall had blocked ICMP from external IPs(HE IPv4 address). How did you get Airtel to unblock traffic coming from the IPv4 Hurricane Electric ?
Hi Kaustubh,
For protocol
41(6in4) tunnels (which HE tunnel is), you either need a protocol41aware CPE or you need to bypass NAT. I keep my CPE (modem) set in Bridge mode, and initiatePPPoEfrom my host. So, no NAT, all traffic from Internet comes at the host, and external IP address is also assigned to the host.HTH
P.S. I didn’t get Airtel to unblock that traffic, it’s already unblocked.
Hey Ashish,
Thanks for your reply. Could you let me know what type of connection do you have? I have ADSL Broadband connection where I dont have a static IP from Airtel, but my CPE WAN Interface is connected to an Airtel DHCP Server which assigns the CPE a dynamic public IP address. Now to create a tunnel the HE IPv6 endpoint must be able to ping my public IPv4 address which is not possible, because Airtel has blocked ICMP(prolly at their DHCP itself). Any pointers?
TIA
Hi Kaustubh,
I’m on a similar connection, but I don’t get any address from Airtel
DHCP, butPPPoE, and of-course address is dynamic. ThePPPoEconnection is initiated from my box. I’m able to ping my IP address (on my PC) from outside servers, so I don’t see any issues with Airtel blocking ICMP. As I said earlier, set your modem in Bridge mode, i.e. instead of configuring ATM VC inPPPoEmode, change it toBridgemode in your CPE. And then dial internet from PPPoE client on your PC.HTH
