Thanks for the quick response. I use vigor to vigor IPSEC VPN (LAN to LAN) on BT Infinity and it no longer works. Can you confirm you have this working on BT Infinity?

I don't have a BT line, but I am using an FTTC broadband.

I've managed to get this working but not exactly how I wanted it.

I wanted the BT Infinity site to call the remote site because the remote site has a fixed IP. This will not work, however if I configure the remote site with the fixed IP to dial the BT Infinity site, it works!

I'm guessing the Infinity modem is preventing the outbound VPN call for some reason.
