Problems to get up multiples networks in VPN with sonicwall and fortinet

The scenario is the following:

A customer is defining several subnets in the fortinet with static Ip and the same on the other end with sonciwall.

10.1.0.0 mask 255.255..255.0

10.1.1.0

10.1.2.0

10.1.3.0,

10.1.4.0

10.1.5.0

We follow this articule and works very goog with only 1 network.

At the moment when you want to add a second network in the same group it doesnt get active.

Any idea about this issue.

    Follow the below steps and try to configure both end;

    Sonicwall Configuration:

    Navigate to the VPN--> Policy--> Edit-->Network; In the local Networks create a address object Group and add the Sonicwall side multiple subnets (if you need to connect those with fortinet. if it's only one subnet, select the Lan Subnet).

    Then the Remote Networks, Create address object group and add those Fortnet side multiple subnets.

    Once you done above steps, Navigate to the Fortinet side and follow the as same as below;

    Fortinet Configuration:

    Step-1

    Step-2

    Step-3

    Hope above steps will solve your issue.
