different subnets for same zone

Tarek,

how they are connected this 2 additional networks? VPN, additional VLAN, separate network?

Can you provide more info?

Thanks.

hello lferrara , thank you for your answer .

the networks are all connected with cisco routers , these routers act as a gateway as well to the sites 

in another world i have a router in Site1 connected by an antenna to the router in Site2 and a router in Site3

all are interconnected 

I can reach the internal network in any site ( as long as they have the respective router as a gateway )

please let me know if this is enough 

Tarek,

so you have XG and then the Cisco is the XG default gateway, right? Did you add the additional networks inside the Unicast Route under System > Routing > Static Routing?

Also make sure a policy rule exist to allow traffic from LAN to additional networks and vice-versa.

hello

I cannot add the cisco as gateway to the XG lan interface ..it is greyed out ..

also how to add additional networks ? I have lan to lan enabled

Terek,

can you share some screenshot of your config?

Thanks.

Tarek,

create additional unicast route under System > Routing > Static Routing.

Also make sure a policy rule exist to allow traffic from LAN to additional networks and vice-versa.

how to create additional networks and what routes should i add ?
