Dave not nuts lol. Yes am running IPSEC VPN - appreciate any additional comments on this as far as I can tell this is TCP traffic and the WAN has no way to know that it is UDP inside therefore errors packets dropped over VPN will get retransmitted no?

Obviously running PP over the VPN is only going to show the source and destination that is why I did the testing outside the tunnel to see whats happening through the hops that the VPN runs over.
