No Traffic over l2tp VPN
Hi i have a problem that no traffic appears to travel over a vpn link to a remote office when initiated from windows 7 pro, i have no problems with xp or vista or even with xp mode in windows 7 they all work fine.Remote office has a draytek router providing the endpoint.The connection initates and authenticates fine and will stay connected for hours i am however unable to ping, tracert, run rdc, access the router or any server via browser. Currently i have disabled ipv6 and the windows 7 firewall to try to get as close to vista or xp as possible both of which work fine. I have had connection but only briefly and when i disconnect i cannot restablish even though the settings have not changed, most of the time it simply won't establish rdc which is the primary use for me.I cant install the other copies to staff laptops as i am not convinced that outlook will sync with the exchange server all the time i cant get a simple ping to respond.could it be some odd dns issue?thanks for any help Paul

Paste your route table first. To get it, input route print in the command console.
