Compartmentalize vlans...

Hi,

you would have to create reject rules between VLANs for each combination.

VLAN 1 on an XG, try to avoid using that until v17b has been tested.

Can you give me an example of a rule? I'm still trying to figure out the method of thinking when it comes to designing these rules. Coming from pfsense ha.

I've created a rule that prevents any of the vlans from talking to the entire LAN section. However LAN can talk to them. They are still able to get out to the web. It was end of the day so I didn't get to test if they could communicate between each other.

Hi,

you will  need one for each direction. I just created and tested this rule to make sure I had the structure correct.

Ian,

inside the source/destination network Port should not be used (because they do not work). IP, Subnet, ip-list should be used.

Hi Luk,

The rule I posted actually works, I tried it our before posting. Somewhere something has been fixed in 5.7 mr7 maybe?

Ian,

since first version, firewall rules do not accept port on source network.

I remember even a Sophos KB where they say do not use ports inside source network (quite new KB than what discovered from community) but I cannot find it.

Hi Luk,

when I initially tested the rule it blocked access, now no effect. Deleted it.
