Hi, I have the VMware appliance on 7.511 and I am having trouble with IPSec VPNs.
The VPN configures no problem and the tunnel appears UP, but when I try and ping from the remote location to the Astaro protected network there is no response. However if I leave the remote ping running, go to the target network and ping back along the tunnel (which works without the loss of a single packet), when I log back on the remote site the pings are then running fine.
The tunnel is then fine until it drops again after a period of no use, at which point I cannot use it from the remote site until I once again ping from the target site back down the tunnel.
It almost seems like the initial ping is being blocked by a firewall and not bringing the tunnel fully up, but then why does it suddenly spring to life when a ping in the reverse direction is done?
This occurs on both of two VPNs I want to use, one from a Draytek router and one from a SonicWall NSA firewall. Neither have ever shown any problems with VPNs before.
Regards,
John
