Zywall 110: Subnet Problem with IPSec VPN

lbu

We have a Zywall 110 with two IPSec VPN connection.

First VPN connects to the remote network 10.10.125.0/24 (10.10.125.1 - 10.10.125.254)

Second VPN connects to the remote network 10.10.0.0/18 (10.10.0.1 - 10.10.63.254)

In the VPN Configuration the Network mask is displayed correctly (Remote Policy: SUBNET, 10.10.0.0/18).

But under Maintenance > Packet Flow Explore > Routing Status > Dynamic VPN the route is wrong for the second VPN: 10.10.10.0 - 255.255.255.255.

So it's overlapping and not working. Looks like a Bug, the route is not set correctly.

Firmware Version V4.72(AAAA.0)
