Sophos SD-RED 20 and VLANs

Hello, I have the following scenario, I need to transport some VLANs that are on my core switch L3, behind the RED (Appliance), I have already tried to put the Firewall interface marked with the VLANs that I need, in Sophos I grouped the VLANs in a bridge, station behind RED gets ip from guest VLAN but does not browse.

I know it's not a good practice, but I need the Hotspot of my guest network, also in the branches.

  • SD-RED20 is not VLAN aware.
    Possibly the RED ignores the VLAN-tags and just transmits everything.. including the VLAN-tags.
    But i think it is not official supported. (even if it worked with RED15)
    Next, you should check at the branch-switch, if VLAN-packets arrive the switch (VLAN/Port statistics or a packet capture).
    If this is working, the client should get an IP or be able to ping the gateway.

  • Yes, I understand that SD-RED 20 ignores the VLANs tags and just broadcasts everything, I put a Switch behind the RED and put the port as Tagged, my station receives an IP address from DHCP, I can ping the gateway, but not ping the Internet.

  • ok, try to ping the internet and take a look to the log-viewer.
    if you enable "logging" within your firewall-rules, you should see something.
    Unfortunately, the last "default drop" rule doesn't log. (i build a "drop and log" rule by myself)

    I think there is missing a firewall-rule or a NAT (Masquerade) rule.
