From looking glass or another offsite location ping each end of the tunnel, if there is packet loss, you need to resolve that first.

icmp is working without any losts

I am getting a similar problem, try turning off packet filtering under Advanced settings (Firewall) to see if its Firewall or IPSEC related.

Mine is something to do with firewall as turning it off makes everything work.

turning off packet filtering is not possible, because nat will also turned off :(

[richie1985]

did we have any other idea?
