@janisk thx for the respons.........

i have 3 ethernets with the config :

1. ether1 - ip (10.10.0.251/16) - subnet (255.255.0.0) - static IP
2. ether2 - ip (10.10.13.2/16) - subnet (255.255.0.0) - static IP
3. ether3 - ip (192.168.4.1) - subnet (255.255.0.0) - dhcp IP

Now that just plain doesn't work..... network 1 and network 2 are the same network. Go back to the drawing board!

With two DIFFERENT network interfaces as this
1. ether1 - ip (10.10.0.251/16) - subnet (255.255.0.0) - static IP
2. ether2 - ip (10.10.13.2/16) - subnet (255.255.0.0) - static IP

You have one that is on the network 10.10.x.x (interface1, 10.10.0.251/16 ) and the second that is on network 10.10.x.x (interface 2, 10.10.13.2/16). These are BOTH on the same network..... you are violating the most basic rules in IP and routing!

It's like having Main Street to the left in an intersection AND also Main Street to right... but they are not the same Main Street! How would anyone know which Main Street a specific house number is on?

With bridging you actually connected the two Main Streets together so that they are the same street..

Please read a few primers on basic network design!

@joeri91942 thx for the info......it'ss my mistake here is my new network design.....

now i have 5 ether

ether 1 - > 10.10.0.251/16 (static clients / IP Local)
ether 2 - > 202.165.x.x/24 (IP Public)
ether 5 - > DHCP (IP Local)

i use bridging for ether 1-4.....
i use difrent bridging for ether 5 (cause i want to use a dhcp)
