MACsec usage

Wed May 10, 2023 1:39 pm

Hi

I have the following setup:

Main router RB750Gr3:

interface macsec
add ckn=(hidden) disabled=no interface=ether4 \
mtu=1468 name=macsec111 profile=default

Second router RBwAP2nDr2:

/interface macsec
add ckn=(hidden) disabled=no interface=ether1 \
mtu=1468 name=macsec143 profile=default

Mac sec is running fine:

[admin@Ogrodowa 146] /interface/macsec> print
Flags: I - inactive, X - disabled, R - running
0 R name="macsec111" mtu=1468 interface=ether4 status="open-encrypted"

How can I allow only incoming traffic from macsec111 to passthrough further and block other traffic from interface=ether4 ?

Tried the followin firewall rules at main router:

add action=passthrough chain=forward comment="Pass MACsec 111" in-interface=macsec111
add action=drop chain=forward comment="Block 111" in-interface=ether4

but it does not do the trick :(

Can anyone help please ?
