Thank you for sharing your inputs. I tried Tunnelbroker but I could not setup tunnel as I have no control over Public IP now. As a first stage, their setup tried to ping ICMP the public IP and since ISP has blocked it, it failed. So could not setup anything further. Still I don’t know how it would have redirected the request to my private IP otherwise.

@mmp Netassist doesn't have the silly ping test which HE does. But it is still unlikely to get it working through a CGN.

When choosing a VPS you need to make sure you choose one which will give you a routed prefix (/64 or shorter). Some VPS providers will only give you a /64 link prefix, in some cases it is not even a dedicated link prefix but rather one shared with other customers.

@kasperd: It's not silly. If you can't get something as simple as ICMP pings working (even have the router itself reply to them), then an IPIP tunnel is even more unlikely.

@grawity I have been on at least one network where I had to use Netassist because of that requirement. A 6in4 tunnel worked perfectly fine on that network, but because the network dropped ICMP packets, I could only use Netassist. Besides even if something responds to ICMP echo requests, there is no guarantee that thing will allow 6in4 to work. So the risk of false positives and the risk of false negatives are both so high, that testing for ICMP is pointless. Testing ICMPv6 echo requests inside of 6in4 would OTOH make sense, but I don't know if any 6in4 provider does that.
