Does anyone know if Virgin Media / NTL block PPTP VPN connections?

Last Modified: 2013-11-16
Hi guys; this is a real simple question. Does anyone know if Virgin Media / NTL (same firm now) based cable broadband in the UK block Microsoft based PPTP connections (in either direction on the line)? It is a home based line (not business).

I have a situation where a PPTP connection that was working perfectly is no longer. I've tried everything under the sun, but it is clear that no PPTP connections can leave the site to any other network, and no inbound PPTP connections will come in either. The Firewall is a Netgear FVX538 v2. We have 2 of these firewalls at the other sites, and they work perfectly. All firewalls have the same firmware, and ultaimtely the same configuration. So I cannot work out what is going on!

Note that PPTP Ping was removed from the Windows 2003 support tools.  Download the 2000 versions here: http://www.microsoft.com/downloads/details.aspx?FamilyID=f08d28f3-b835-4847-b810-bb6539362473&DisplayLang=en


Many thanks Steve - I hoped such a tool might exist, I'm downloading this and giving it a go now.....


Hi Steve - sorry I didn't come back here sooner - it's been a very busy week! I worked out the problem in the end - PPTP passthrough was fine, but a replicated DNS zone that shouldn't have replcaited on the remote server was causing the problem. The Zone contined records that related to the internal FQDN of servers at our Surrey site, but the Southampton site got this zone and therefore didn't resolve the external FQDN it need to to see the VPN (that was part of the same domain as the zone).

As soon as I spotted this, I created an external host record in the zone, replicated this, and we were away.

Many thanks for you input - I'm giving you the points because you helped clarify NTL were not the problem, and that PPTP tool will come in handy in the future. Many thanks, and Merry Christmas!

You're welcome.  Glad it's sorted.  Merry Christmas to you too :)
