@sussox:
Ok, now i have checked the above. Filtering brigde is enabled. And all rules are removed on both WAN and LAN. I still see DHCP-ACK in the log of the DHCP-server on the WAN when i renew the lease on the DHCP-client on the LAN. Isnt this strange?
This is driving me crazy.. I have it running with a single rule, blocking ANY protocol from the LAN-net to the WAN. But still the DHCP travels the bridge!
When i disable the bridge, the DHCP stops working (of course) but when using a filtred bridge with no rules (or a single a block all-rule, like above) DHCP still gets through.. Bug?
