 2   10.254.1.4/24      10.254.1.0      ether1

My working network is 10.254.1.0
Behind 10.254.200.0 there is a DHCP server for this network.
But i noticed, that clients from my working network 10.254.1.0 are trying to get an IP from DHCP server 10.254.200.252
How can i disable DHCP request between ether1 and ether2 ?

but i created only one rule - forward

It think it would be better to solve this in switch chip.. but then you must have ether1 and ether2 in same switch group (master and slave interfaces..)
