Routing Issue from Blue to Green

Hi,

I am facing an issue with routing, I am trying to add a route to access Green Network from the Blue Network host. I have added a route to the Firewall to allow all traffic coming from the specific Blue Network host. The host accesses all clients except the Gateway.

Green Network = 192.168.8.0/24
Blue Network = 192.168.11.0/24

The Nethserver IP address is 192.168.8.230

From Green Network I can access the Nethserver using 192.168.11.230 or 192.168.8.230.

From the Blue Network I am not able to Ping and access Nethsever using 192.168.11.230.

Can anyone please help me to find out a way how to access Nethserver using Blue Guest Network?

By adding local rules, I was able to access the gateway from Blue Guest Network.
