Why this can happen ? It pings, it works with main router, it gives internet, but i can connect to it only directrly with lan cable.
Config is almost default, just maked bridge with only one erher1 port, added ip address (10.12.12.1), and turned on DHCP server with pool 10.12.12.100-10.12.12.200 for bridge (ether1)... that's all
