Title: Wildcard netmask in alias or firewall rules
Post by: olest on April 23, 2021, 01:39:06 pm

I need to create a firewall rules that gives access to IP's which ends at e.g. .64

Using another firewall provider we could do this by using wildcard netmasks as this 0.0.0.64/0.0.0.252

Can this be done some how with OPNsense?


We need to do the same as this other Cisco example:
Match all 192.168.x.1 addresses:
permit 192.168.0.1 0.0.255.0
