Help with setting up my tunnel

wrecksan · January 17, 2011, 05:24:11 AM

Hey ive been getting the error message:

Error: Your IPv4 endpoint is unreachable or unstable. Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 66.220.2.74 through your firewall.

I've disabled my firewall, windows firewall and the router firewall and still no luck.

Is there any chance someone could help me? Thanks

What's your IP address?

That error message means that HE is unable to ping your public IPv4 address

My IP Address is 92.17.38.21

Its dynamic IP but that shouldnt matter for setting it up should it?

Code Select


C:\Users\cholzhauer>ping 92.17.38.21

Pinging 92.17.38.21 with 32 bytes of data:
Request timed out.

Ping statistics for 92.17.38.21:

Yes, your IP is dynamic, but it probably doesn't change that often.

Is there anything I'm overlooking with this?

Has to be ;)

If you connect your computer directly to the cable modem/DSL router, does it work?

If it does, there's a setting you missed.

If it doesn't, you've either forgot to disable the firewall on the OS or your ISP is blocking ICMP

Maybe this is just a coincidence or Im having a wrong angle at this, but I googled a bit and, according to this guy,
your ISP carphone warehouse blocks ping requests to their networks.

Is there a way to get round that? I haven't got the facilities to change the wire/wireless as this is on a desktop and havent got any cables long enough :(

I'm not trying to be awkward though sorry

cholzhauer · January 17, 2011, 07:23:17 AM

He's saying that your SOL...ICMP is being blocked before it even gets to you

wrecksan · January 17, 2011, 07:28:16 AM

Oh right, I was referring to that but yeah if its getting blocked before it reaches me I havent got a chance :p Ok thanks very much for your help both of yous :)

The only thing that comes to my mind is looking for a vpn service (there are a few free ones), it might work with one of them, but that depends on a few things.
It most likely only would be useful for doing the certification at most, if theyre not blocking http/smtp etc services.
Either use a completely free one like Hotspotshields (tho the Tunnel didnt work for me), or get a free testing account for a UK based one.

Its always worth a try.
