Welcome to Vodafone Community
Can anyone tell me what light 1 flashing and 3 & 4 solid orange means, I have never been ably to get the Sure Signal working but I have dug it out becasuse the new one I bought seems to be one of the ones that blows up after a couple of years
With the light sequence you're seeing on your Sure Signal @miller75 I'd advise speaking with your Internet Service Provider (ISP) and let them know you're trying to set up a VPN tunnel.
If you have a dynamic IP address, please let them know the IPsec is being transmitted in transit. If it's a static IP address, please advise them that the IPsec is being blocked on an internal firewalled server within the network. I hope this resolves things for you!
