One way access between two subnets
-
I have a 1 and 10 subnet. They both work fine, but I would now like to restrict some access. My 10 subnet if for IOT and Guests. I don't want them to have access to the 1 subnet at all. Additionally I want anyone on the 1 subnet to have full access to the 10 subnet.
I was able to block access to a specific address 192.168.1.1 (the router) with a rule, I then added pass rule on the 10 subnet that says: for IPV4, any source, any port, Desitnation !LAN net. I thought this would only pass traffic out that is not headed to my LAN (subnet 1). But it doesn't seem to do anything. I can easily get to my file server, which is what I don't want.
Do I need to add a block, any, any, destination 192.168.1.0/24, I kind of thought that is what the previous one did.
thanks,

1) Clear your states after you make a rule change. Existing states will continue to function even if blocked by rule.
2) Post up a screenshot of your rules so we can see what you're really doing.
3) Try to avoid using negate operators. If you don't want them to access your LAN, put a block right at the top to prevent it.

Here is what it looks like today:
it does block 192.168.1.1, but that is all. If I change the last rule to a block evertying to the LAN net, then nothing works. I can't even ping my DNS.
thanks for the quick response

Change your block rule from 192.168.1.1 to LAN network and change the protocol from IPv4 TCP to any. Move it under your Plex rule. Change your last access rule from ! LAN net to *. Done.

thank you!
I never tried both of those changes.
