hi It was not working when i applied the rules on the vpn card. But I wondered if maybe bridging of vpn and eth0 was messing this up. I thought it was enough to only apply it to the vpn card root at JOTVPN:~# brctl show bridge name bridge id STP enabled    interfaces bridge 8000.000c29638a7e no           eth0                                                                   vpn so I tried the rules you sent me on the bridge card an now it works. But why is not both rules applied on outgoing traffic?...

Hi Im using tinc to bridge networks together. And im using ebtables to block dhcp traffic for ipv4 on each node in tinc. One of my nodes have recently began using ipv6. The isp is using auto configuration to give out ipv6 addresses. The problem is that every computer in my bridged network is getting ipv6 addresses from that node. The other computers behind the other nodes have no use for ipv6
