Hi
My HN (CentOS, kernel 2.6.18-92.1.1.el5.028stab057.2) has 4 vlans configured (see attachment for details).
There are multiple CT, on different vlans. The problem I am having is that one CT is able to communicate with another on a different vlan, where there should be firewall rules protecting it. They are also able to communicate with other hosts on the said vlans.
Is it possible to force outgoing traffic through the vlan trunk (eth1) and stop it from being routed "internally" ?
Please let me know if further information is required to answer this question.
(eth1 is the vlan trunk, eth0 is configured in a bridge with the HN ip virbr0 and a few other CT interfaces because of special needs.)
Regards,
Bjorn
