All DHCP requests are routed to the gateway/firewall (No DHCP relay agent). The firewall has IP-address 192.168.0.254 and IP-alias 192.168.1.254.
The above situation works ok. But all traffic from 192.168.0.x to 192.168.1.x and vice versa is routed by the gateway. This poses no problem in daily use. When there is a deployment of workstation images its hard for the gateway (network performance).
Is there a possibility to tackle this issue without requiring another IP range (172.16.x or 10.x.x).
I think it is not in accordance with the standard to change the subnet to 255.255.254.0.
