Does ZeroShell support VLAN IEEE 802.1Q?
Yes, ZeroShell supports trunk protocol IEEE 802.1Q. For each network interface (Ethernet card, bridge, VPN LAN-to-LAN and VPN bond) it is possible to add one or more VLANs by specifying the VLANID between 1 and 4094. Practically, what you get is a virtual sub-interface whose name is the name of the main interface merged to the VLANID (separated by a point). For example, the VLAN 1250 applied on the ETH00 is represented by the logical interface ETH00.1250. To this VLAN, represented as a normal interface, you can add IP addresses, enable routing and NAT, apply firewall rules, attribute services such as DHCP, DNS or a Captive Portal. • I configured a VLAN on a ZeroShell Ethernet port, but the packets that are too big don’t reach their destination. What does it depend on? Unfortunately, for a minority of Ethernet and FastEthernet cards there is no support for trunking 802.1Q within the Linux kernel. 802.1Q protocol includes a maximum size of 1522 byte (1518 normal + 4 for the tag) for Ethe
