network on vm weird

[xxx31fr]

hi,

I've some weird things with my LCX container on my Kimsufi.

I detail:

On the host, there is 3 NICs:
1/ eth0
2/ vmbr0 | linux bridge | port slave : eth0 | ip publique de mon srv...
3/ vmbr 1 | linux bridge [ port slave : dummy0 | ip: 10.10.12.254/24

on my LCX Container
1 NIC net0, called eth0, bridge mode on VMBR1 and ip address 10.10.12.1/24

On host (proxmox), I runned the following commands:
echo 1 > /proc/sys/net/ipv4/ip_forward
and
iptables -t nat -A POSTROUTING -s 10.10.12.0/24 -o vmbr1 -j MASQUERADE

From my container, I can ping 8.8.8.8 or any domain name, example google.com

But an apt-get update failed:
ex:
Failed to fetch http://security.ubuntu.com/ubuntu/dists/trusty-security/main/binary-amd64/Packages 404 Not Found [IP: 91.189.88.149 80]

I don't understand where is the problem

Thanks

that's not a network, but a configuration issue - it seems like the "Packages" file is missing, but "Packages.gz" and "Packages.bz2": http://security.ubuntu.com/ubuntu/dists/trusty-security/main/binary-amd64/

you can contact the Ubuntu people about this issue or convince your apt to fetch the compressed packages file anyway, it's not related to PVE at all

no, no, you're wrong,
It's seem like all http request could not be reach, because, when I open lynx, I can't access any http/https links

but, a ping with any domain name works
