I have ubuntu (8.10 with kernel from 8.04 supporting openv) box (HN) with 2 NIC: eth0 - ISP1, eth1 - LAN (192.168.7.1).
It acts as simple NAT (iptables -A POSTROUTING -s 192.168.7.0/24 -j MASQUERADE), so ip_forward is enabled.
On eth1 I created bridge (br0) to let VE see the network.
Also this box acts as DHCP-server.
On the other hand I have adsl-modem configured as router (192.168.7.3, ISP2). I'm trying to pass all traffic from some machines through ISP2. It is easily done by specifying "option routers 192.168.7.3;" in dhcpd.conf per machine. And it works fine with physical boxes, but not with VE (192.168.7.6).
In VE I'm trying to add default route, but it has no effect - no packets are going through router:
root@gretchin:/# ping ya.ru
PING ya.ru (213.180.204.8) 56(84) bytes of data.
--- ya.ru ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2007ms
root@gretchin:/# traceroute ya.ru
traceroute to ya.ru (213.180.204.8), 30 hops max, 40 byte packets
1 192.168.7.3 (192.168.7.3) 2.059 ms 2.693 ms 2.997 ms
2 * * *
I'm sure that it isn't router's issue, cause doing such on HN helps:
ip rule add from 192.168.7.6 table 6
ip route add default dev br0 via 192.168.7.3 table 6
But why it isn't running without adding routing rules on HN?
