newbie sort of question: does slave ifs of a bridge need to iptabled? does one need to forward/input etc.. them? It should be only bridges in this situation, right? also maybe someone could share his/her thoughts on this one problem I have, that boggles my mind for I'm unable to fix it, namely: I had to introduce additional routing tablesand rules in order to allow for source based routing, before it was working what was? - guests(VMs) behind a bridge interface(that comprised of tap interfaces, one tap IF per VM) could see/reach hostsystem one specific, separate/physical interface now these guests cannot do that anymore, I think ever since I introduced source based routes into this environment I should try to provide you with better picture.... VM(via tap) --- HOST VM(via tap) --- ------ > br0(taps + em4 + eth0); br1(em1 + eth1); em2; em3 etc ...... --- now, VMsreach allthe interfaces but one em3! VMs also reach outside world to which em3 is the gateway(masquerade) naturally VMS are reachable from the HOST itself and each other, but not from/behind br1 VMs are on/behind br0 here are rutes+rules: ip route add table internal from 172.25.12.0/24 to 192.168.2.64/27 via 192.168.2.65 dev br0 ip route add table internal from 172.25.12.0/24 to 192.168.2.0/24 via 192.168.2.100 dev br1 ip route add table internal to 172.25.12.0/24 via 172.25.12.203 dev em2 ip route add table external to 192.168.2.0/24 via 192.168.2.100 ip route add table external to 192.168.2.0/27 via 192.168.2.65 ip route add table external to ext_NET/24 dev em3 ip route add table external default viaext_IP(via em3) ip rule add from 172.25.12.0/24 table internal ip rule add from 192.168.2.0/24 table internal ip rule add from ext_NET table external or is it iptables?? but there is: -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT -A FORWARD -i br+ -o br+ -m state --state NEW -j ACCEPT i really cannot get my head around it, have tampered with routes+rules, iptables..cannot.. anybody's input much! appreciated regards -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
