    Hi all, I’m using zeroshell beta 16 on an alix.
    I’ve created two vlan for the eth0 nic: eth0.50, eth0.52.

    I have then a client in vlan 50 that can ping zeroshell and that can also reach Internet (nat is working then).
    A second client, is on vlan 52. It can ping zeroshell but it can’t reach Internet.

    Off course zeroshell is the gateway of the two client:
    client 192.168.50.2 vlan 50 -> gw 192.168.50.1 (eth0.50 zeroshell)
    client 192.168.52.2 vlan 50 -> gw 192.168.52.1 (eth0.52 zeroshell)

    The true configuration of the zeroshell I’m using is quiete complex but I think I summurized the problem.

    What can I check to understund why only vlan 50 goes through nat?

    Thank you!

    Firewall rules forward chain ?? Somethings about vlan 52 ? Default policy is drop ? Proxy enabled ?

    The chain forward policy was accept but there were several unusefull active rules.
    I disabled them and it seems to be working fine.

    Proxy is disabled.

    Thank you.
