O2 and the mysterious case of the missing VPN


It may as well be a murder mystery. I’ve killed the best part of a week on this and I’m still without a satisfactory resolution.

The story goes like this. I rely upon a VPN connection to access the office from home. I don’t use it all the time but when something goes wrong and I need access to the servers its invaluable. I’m 25 miles and the best part of an hour away from the office. At some point the week before last my VPN stopped working. As with all the best stories there were sub plots and red herrings. In my case another user had lost connection which lead me to think it was the common denominator – the VPN access point. So after much investigation and test it turned out that in the other users case it was a forgotten password and the timing was pure coincidence. Armed with that knowledge I made some progress.

I had been hindered by the fact that the only place i could test from was my home office. Had I been able to try from elsewhere I may have spotted this earlier but having found that the problem was only affecting me I tried a little experiment. I disconnected my iPhone from Wifi, configured it for VPN and managed to successfully connect via the mobile data network. Reconnect to the Wifi and the connection failed. This pointed the finger squarely at my O2 router. After a bit of rummaging through support forums I found I was not alone.

I called O2 armed with this knowledge and the experience of previous callers. The first person I talked to said she was aware of the problem and I needed to talk to second line support. I found myself on hold only to be cut off. I called back. The second guy was in denial of the problem but I insisted to talk to the second line techies.. he cut me off. On the third attempt I got the “we don’t support VPN” that I had been warned about in the forums. He tried to fob me off on my works system administrator. That wasn’t going to work as he was talking to him. He tried a number of other excuses which didn’t work other than elevate my own frustration levels. Finally he said that the necessary tech guys don’t work weekends and he would get one to call me on Monday to schedule a firmware downgrade. Finally the result I wanted if not to the expected timetable.

Once off the phone I thought I’d try and sort it myself but O2′s tools are Windows only. I tried VMWare with a copy of Vista and the password was rejected. I tried another route with BE support but I needed a member login. Having gone round the houses I finally found a copy of earlier firmware and a Thomson update tool. (for those reading who don’t know O2 broadband is BE and the O2 Wireless Box II is a Thomson). Unfortunately I hit the brick wall of rejected password again. I know the the username SuperUser and the password O2Br0ad64nd is right as I can login via a browser. In the end I’d wasted more time.

I’ll wait for a call on Monday and post an update. In the meantime I’m going to research alternative Broadband suppliers. Its a shame as O2 to date have been great but this is a deal breaker. And if anyone from O2 is reading this I can say with an element of certainty that if you lose my broadband custom you will also lose 3 personal iPhone contracts (Vodafone with a Sure Signal Femtocell looks good) and it will be a nail in the coffin for your (large) contract at work.

Interesting to hear your troubles, as my VPN has also mysteriously stopped working, as of Thursday last week.

I’m yet to call O2, as I’ve been dealing with my own system admin to make sure the problem isn’t on our end. It appears not to be.

Let me know how you get on. I’ll be ringing O2 tomorrow morning. I really, really need this VPN!

Got exactly the same problem, thought it was me till I realised all my vpn connections were affected.

I have had nothing but trouble with the O2 Thompson router. Two weeks ago it decided to forget everything and I had to reconfigure my home network.

I am in the process of trawling the forums to find a solution. Might be shelling out for a draytek router.

Here’s a quick update. I’ll have a closer look tomorrow (long day) but…

I came home to find my network broken. More specifically O2 seem to have downgraded my firmware. In doing so they trashed the DHCP pool so I had to recreate it.

The firmware version they stuck on is 7.4.20.5 and from what I’ve read this is still a problem. The suggestion is that I need 7.4.20.4

Well, I got off the phone with O2 about thirty minutes ago, with them agreeing to downgrade my firmware, though they reckoned it probably wouldn’t get done ’til the end of the week.

My network went down ten minutes ago and refused to connect, so after a hard reset of the router, my firmware is now 7.2.20.5, and my VPN is working!

How’re you getting on, Redsmartie?

As per my latest post I was one step away from resolution. Once O2 initiated a factory default restore with the 7.4.20.5 firmware in place it started working.

Well… at least they seem more aware of the issue now, if no more helpful.
Like you I am the system Admin for my company, and Mac user, and occasionally need to VPN into my network. All was well with o2 and I never had an issue connecting, until I came to do so a couple of days ago.
At first, the answer was “We are unaware of any issue with VPN connections. Maybe there is a problem at the server end.”
It seemed odd to me (since I administer the system) but we have just upgraded our server hardware, so it was theoretically possible, I guessed.
Well, the problem isn’t with the server (I could connect from my iPhone) so i called them back.
This time I got the “We don’t support VPN connections, they can be used to bypass bandwidth shaping measures” answer. However when i reminded them that I am on an LLU connection, which they say isn’t throttled they said they would need to transfer me… and got cut off during the transfer (sound familiar?)

By the time I called them back about 10 minutes ago, they seemed to know all about the VPN issued, had a list of how to resolve it myself (using the installation CD… on Windows) however, when I explained that I am on a mac, neither the tech support guy, nor his supervisor were aware of any way to remotely downgrade the firmware.
They insisted that it simply wasn’t possible, and needed to be done using the CD.
One step forward, two steps back it would seem.
Guess i need to dig out my XP cd and load bootcamp again (Grrrrrrr)

Be insistent with them and force your technical knowledge on them. That’s the only way I made progress.. the old “I know more than you” routine, which incidentally was true.

As you’ve seen from my post their responses are inconsistent but remote downgrades ARE possible and they ARE carrying them out.

I was an o2 mobile customer, there customer service attitude failed me and I swore never to use them again. After many years and seeing someone else using a fast home broadband service from them I decided that maybe they have changed. Now my VPN is dead thanks to them (I tested connecting via my 3 dongle and straight into the VPN). I don’t have the techyness to argue the toss with them, I’ll just vote with my wallet. Yet another faceless couldn’t give a toss huge company.

I’d give them a call. There’s enough info in this thread to see you through and to quote. Besides I think I was at the bleeding edge of the problem and I’d expect that their support people will be well briefed now.

I too had problem with my VPN connection over O2′s broadband. In my case it turned out to be the latest firmware version for the O2 Wireless box (8.2.23.0) has caused problems with PPTP VPN connections and to resolve it I had to downgrade the firmware and block the port that O2 use to remotely update the router. Now everything is working again.

I written up a full blog post about my VPN issues with O2 Wireless Box II and how I resolved it.

It’s now May and O2 have “upgraded” my box to 7.4.20.5 VPN not working. Wish I’d found this thread before I rang them.
I am using an IPCOP firewall behind the O2 box and am using a MacBook to access the VPN with IPSecuritas. It works fine via 3G network.
What are the other settings (if any) on the O2 box that will make this work? (I have tried with the MacBook plugged direct into the O2 box)

O2 have to initiate a factory reset although I see no reason you can’t do that yourself. You’ll probably have to log in as superuser (do a Google for that)

Just got off the phone to 02 – they are downgrading my firmware and it should be done within 24hrs.

Fingers Crossed!!

Thank you.

Have previously phoned o2 3 times and got nowhere. In the end googled ‘does o2 block vpn’ and found your comments and seem to have now made progress.

It definately helps to sound like you know what you are talking about when you phone the helpline!!

Firmware downgraded and 24 hours later we are able to access vpn.

Thanks for all your previous comments.

Just started a new job and now VPN is important to me again (last job didn’t really need it that often).

The girl at O2 understood the situation straight away, but after being on hold she came back and explained my firmware (8.2.7.7) was fine for VPN.

Eventually we tried simply holding a pin in the Wireless-box-ii’s reset button (with the power on) until the lights flashed (about 10s).

Low and behold – all passwords reset, etc, but the VPN started working.
(http://o2wirelessbox.lan – and the ‘Administrator’ password starts ‘CP’ and is found under your wireless-ii box)

I was unable to connect last week (5 Jan) but today I tried again and it was fine.

I am running O2 Wireless Box II with 8.2.7.7. I attempted to do a firmware downgrade but was running Windows 7 in a virtual environment so it didn’t work. The box did reset itself though.

After reading post 16 I thought I would just try the VPN again and low and behold – it worked!! Very happy.
