L2TP vpn can't get connected

[Posix]

Hi, with Optus NBN, I'm running an L2TP vpn ( with ipsec) server in my home PC, and I tried to dial vpn into my home PC through my Optus mobile phone, the connection is always failure.  

    Is this vpn protocal banned in Optus network? How can I get it through?

Thanks,

J

Hi @Posix, you'll have to discuss this with our tech team on 131344. This is something they can only confirm. Please do let us know once you've spoken to know with them.

@Posix I'm using L2TP/IPSec VPN no problems.  I terminate my Optus NBN connection at my Vyatta-based firewall (bridged modem).  No issues connecting from my iPhone over Optus mobile broadband to home.

Firewall rules and NAT issues are the two things you need to double-check by checking packets arriving and correctly processed.

PS: I have a static IP.

Have you tried to contact with your VPN provider? I faced the same issue and when i contacted my VPN provider, they solved the issue.

I was using PureVPN for Wifi Security

Hi There,

I wanted to make some enquiries on this matter ,

I am looking to set a client up with a VPN

I am looking for some setup / config device surrounding an L2TP VPN setup and wanted to enquire what the port forwarding / NAT situation is. 

I know that I can establish a PPTP connection to the resources fine currently 

Though I am receiving an error about NAT which could be the config of the Modem/ router or Port forwarding not being setup / NAT settings.

The Client is running Windows 10 , I have allowed the ports on their device itself and made changes  to the registry to allow UDP Encapsulation.

So any help which can be provided would certainly be appreciated
