I have just had to change ISP from BT Business as my company no longer provide it. I have gone with PlusNet but can't get the VPN which allows me to work from home to be accepted. When I asked the PlusNet helpdesk they told me that "This is a setting that can be changed on your router however we do not support this as we block these ports for security"
The settings in question (according to my work helpdesk) are:
"Work with your ISP (internet service provider) to verify and ensure the ports below are open:
Packet filters for Point-to-Point Tunneling Protocol (PPTP)
TCP destination port of 1723 = PPTP tunnel maintenance traffic
IP Protocol ID of 47 = PPTP tunneled data
Packet filters for Layer Two Tunneling Protocol over Internet Protocol security (L2TP/IPSec)
UDP destination port of 500 = Internet Key Exchange (IKE) traffic
UDP destination port of 1701 = allows L2TP traffic
UDP destination port of 4500 = IPSec network address translator traversal (NAT-T) traffic"
Can anyone help me on this please? Is there any way I can amend my settings on my router - a Belkin N300 - to allow the VPN to work?
Or do I have to find an ISP whose broadband will allow this? If so, how will I know which ISPs do this?
As you can tell, I'm not a techno-whizz, and any help will be gratefully received.
