How to I create a network group/alias for rfc1918 subnets?

[g0nz0uk]

Hello,
I'm coming over from pfSense and I am trying to create a rfc1918 group to block local private subnets for my guest network.

In pfSense I just create a new alias and add the name and subnets, what am I doing wrong here as I don't get the option to add the local subnets?

You have to type them into the "content" section

Thanks, I've added 10.0.0.0/8, 192.168.0.0/16 and 172.16.0.0/12

Now I need to create an Alias for port 3074 on TCP and UDP, what is the format for this please?

Create an alias with that Port
After than you have to create a Rule for UDP with that Alias. Same for TCP

You should read the Docs
https://docs.opnsense.org/manual/aliases.html

It's the same like in pfsense
