I've noticed a strange and frustrating problem when connecting to SSL sites on Vodafones Wellington cable (formerly TelstraClear) network. I can't seem to connect to any of our (work) network appliances via ssl anymore. If I switch to tethering my Telecom 4G mobile, suddenly everything works (and the internet seems much, much faster overall). Things also work right when I use a VPN.

I can ping the IP address of the SSL site just fine, I just can't connect. I've tried multiple browsers, computers, and even OS's. No dice.

Everything seemed to work ok, albeit very slowly a few weeks ago. The problems disappear when I use a VPN so I suspect Vodafone is at fault.

Is anyone else seeing connection issues lately on Vodafones cable network?

Happyfunball, if you want to PM me a few examples I can try connecting from here (I have both Vodafone cable and Snap DSL so I can compare).

I do use a couple of SSL-enabled websites and see no problem but it could be specific. Let me know.

Any other examples or just those you sent me? They both fail for me on Vodafone cable but work fine on Snap DSL.

Those are all from the same provider. Do you have examples from other providers? I wonder if Vodafone's IP range is blocked on the other side - perhaps you should contact them?

I have contacted them, I work there. No blocks.

Thanks for confirming its a Vodafone issue. I see the same thing on other sites and especially network appliances but that seems intermittent.

I guess I have to burn an hour or two talking to a friendly Filipino :(

Thanks Freitasm for helping out. Wouldnt suspect blocked IP ranges. Bad routes most likely. Works fine from xDSL. Trace route supplied below.

Ping works ok for me on Vodafone, the connection is dropped on the HTTP reply. The web server is contacted but doesn't come back. ssh works ok, just not port 80 or 443, and only for the last 3 hours! And its the whole subnet, which consists of many network appliances and servers.

I suspect a filter somewhere, and AFAIK the Vodafone link is the weakest link here as far as shaping is concerned.

Any tips on who I should talk to about this?

You can start now by turning the router off/on, turning the modem off/on, rebooting PC, connecting the PC directly to the modem bypassing the router, etc - they're going to ask you to do this anyway.

All done a long time ago, I'm way past that.

If you can't connect either than we know its not my router LOL :)

Man I hate that tech support script. :/

Tell them to log a ticket for "Cant browse single websites" Provide trace routes and path pings plus failed attempts with URL and time. If works with another DNS e.g google DNS.. They will look into further.

I logged a ticket with them after 40 minutes on hold. They bumped me to lvl 2, which is apparently an email :]

Anyone else on cable having problems connecting to this site?: www.vimyfoundation.ca

Routing problems are one of the reasons I switched from cable to Snap fiber. They couldn't route directly to Australia, a 30ms trip, it always had to go via somewhere that took 150ms.
