Which ISP's block VPN by default

My company is ramping up work from home due to social distancing.

Could people advise what ISP's block VPN by default due to their parental control tools etc?

I have found Virgin block VPN due to Web Safe. Anyone else?

When you say VPN are you sure you do not meant Remote Desktop/Teamviewer some ISP do block these (can be removed on request) reason for block being that scammers get people to install these and use them to take control of PC to carry out their scam

I'm on BT with their protection turned on and can confirm Cisco VPN works fine.

I used to be a Plusnet customer and while their protection doesn't block VPN, they have an IP range which used to be registered in the US and can cause VPN issues if you are unlucky enough to get an IP from that range.

No this is a secure tunnelled VPN client we use on their laptops when out and about.

It still is registered in the US, "BT America" with a Californian address. I don't think ARIN assigned addresses are allowed to have a UK address, otherwise they would have done it by now.

You should have asked which allow VPNs as well so you end up with a VPN list and a No-VPN list.

BT uses VPNs for most of it's Homeworkers so no problems.

So SKY and TalkTalk, BT allow use of home VPN service. I have not heard from my company of any that do not allow the "corporate" vpn service to allow working from home.


So. Just use it.

You do find some ARIN blocks with UK addresses when the service is based in that RIR region. You can also find the opposite which is what they're doing with some of the old Infonet/BTA blocks.

There is an increasing number of blocks that were assigned by ARIN moving to the RIPE service region (and others), although you have to wonder if that is because of the fixed fees RIPE now have instead of paying $4,000 a year to ARIN for a /16.

Now that v4 is exhausted, the RIRs don't seem to care as much with the plentiful supply of v6.

As I said, Virgin Media block VPN using the Web Safe tool.

Plusnet also.

I need to know which ISP's with these parental control shields block VPN.

So end users can't 'just use it' because it won't connect due to these shields being enabled by default.

I know EE and BT allow VPN even with the parental control shields on. I've been on both recently.

The other big ISP's our staff use are Sky and TT.
