We have a client who uses a draytek Vigour 2820vn as an endpoint of a vpn tunnel to our Watchguard X2500 firewall.

Currently the issue is that the tunnel while still working and showing as active is preventing access for their PC's to our network.

If we ping any device on the clients network we get a response from the draytek unit. The client is at a loss as to what the cause is.

The VPN tunnel allows access
from 192.168.46.0/24 ( client side )
to 192.168.10.0/24 ( our side )
Draytek address 192.168.46.69 on Client LAN

If we ping 192.168.46.20 from our end the reponse comes from 192.168.46.69

The draytek was configured by an employee who left their employment and we do not have direct access to the Draytek unit - although we are working on that.

Is there a setting that would cause this issue ?

We have other clients using Draytek units who do not experience this problem.
