But, yes, it is possible to replace three NICs with single NIC plus three VLANs. Surely for DHCP stuff. If three NICs were choose due high bandwidth usage, that can't be solved by "VLAN".I guess nick bonding could be used with VLAN.
Hello, ok trying a solution to resolv dnsmasq with vlans and one nic, I do next
I reconfigured the dnsmasq with this and the mikrotik router with tagged vlans.
