Hi,
I have
br0 - LAN
br1 - Internet
br2 - WLAN
First problem:
Main Linux machine which is running all this can't connect to internet.
Physical machines connected to this bridge via switches can access internet.
So how I add default route as br1 or straight vlan 333? For some weird
reason it seems to get only one packet.
Like:
# ping -c 4 ping.funet.fi
PING ns-secondary.funet.fi (128.214.248.132) 56(84) bytes of data.
From 192.168.1.1 icmp_seq=2 Destination Host Unreachable
From 192.168.1.1 icmp_seq=3 Destination Host Unreachable
From 192.168.1.1 icmp_seq=4 Destination Host Unreachable
--- ns-secondary.funet.fi ping statistics ---
4 packets transmitted, 0 received, +3 errors, 100% packet loss, time 3000ms
, pipe 3
# ping -c 4 -I br1 ping.funet.fi
PING ns-secondary.funet.fi (128.214.248.132) from 62.204.1.12 br1:
56(84) bytes of data.
From 62.204.1.12 icmp_seq=2 Destination Host Unreachable
From 62.204.1.12 icmp_seq=3 Destination Host Unreachable
From 62.204.1.12 icmp_seq=4 Destination Host Unreachable
--- ns-secondary.funet.fi ping statistics ---
4 packets transmitted, 0 received, +3 errors, 100% packet loss, time 2999ms
, pipe 3
# ping -c 4 -I eth1.333 ping.funet.fi
PING ns-secondary.funet.fi (128.214.248.132) from 192.168.0.1 eth1.333:
56(84) bytes of data.
From 192.168.0.1 icmp_seq=2 Destination Host Unreachable
From 192.168.0.1 icmp_seq=3 Destination Host Unreachable
From 192.168.0.1 icmp_seq=4 Destination Host Unreachable
--- ns-secondary.funet.fi ping statistics ---
4 packets transmitted, 0 received, +3 errors, 100% packet loss, time 3001ms
, pipe 3
How it sends UDP packet (DNS) through br1 and gets answer and then nothing?
Second problem:
What do I add to br0 and br2 so those can access internet through br1?

This seems to be a IP routing issue, not a bridging issue at all. You have set up default gateways for your own IP in the interfaces configuration for br0 and br2. Things should be better if you get rid of the gateway lines in the br0 and br2 sections.
