I have a strange one I have setup an IPsec VPN between 2 sites I can ping some addresses ie 10.x.x.10 but not others 10.x.x.9.When dialing in PPTP from Site A using dial up connection can ping all no problem. I have a Lan to Lan VPN (2960-3900) setup and working fine.

Any ideas would be most welcome as its not running ideally and I'm getting no response from Draytek support (email)
