NOTE 3:
L3 Firewall settings do not impact packets received and redirected from/to Radio channel. The
problem described in NOTE 2 will not happen when the affected RipEX router is a radio repeater,
i.e. when it uses solely the radio channel for both the input and output.
MAC (L2)
List box: Off, On
Default = Off
If "On" and when in the Router mode, simplified Layer 2 Linux firewall is activated:
Filter mode
List box: Blacklist, Whitelist
Default = Blacklist
Blacklist
The MAC addresses listed in the table are blocked, i.e. all packets to/from them are dis-
carded. The traffic to/from other MAC addresses is allowed.
Whitelist
Only the MAC addresses listed in the table are allowed, i.e. only packets to/from them
are allowed. The traffic to/from other MAC addresses is blocked.
If "On" and when in the Bridge mode, a standard Layer 2 Linux firewall is activated.
Protocol
List box: possible values
Default = All
All – Ethertype is not checked, i.e. no packets are selected by the filter. addresses is al-
lowed.
Manual – set 2 octets of Ethertype (in Ethernet frame) which are selected by the filter.
Not VLAN – only frames which are not embedded in VLAN are selected by the filter.
All VLAN – only VLAN frames are selected by the filter.
IPv4 – only IPv4 frames are selected by the filter.
IPv6 – only IPv6 frames are selected by the filter.
ARP – only ARP frames are selected by the filter.
LENGTH – only Ethernet frames from obsolete IEEE 802.3 Ethernet are selected by the
filter.
VLAN
Default = None
This VLAN filter supersedes settings in Protocol. Frames with this ID of the 1st level VLAN
will be selected by the filter.
NOTE: When VLAN field is set, all settings in Protocol are applied to frame embedded in
VLAN (Ethertype of the 2nd level).
