Firewall allowing connection against set rules?

[LeroyM4567]

Hello! Looking for some help with an issue I'm having.

I have a new OPNsense 22.1.7 install and I have multiple interfaces. The issue is follows:

I have client A on interface LAN that is allowed to ping or otherwise communicate to anything on interface LAN2. However, nothing on interface LAN2 is allowed to talk to anything on interface LAN.

The problem is, if I initiate a ping from a machine on LAN to a machine on LAN2, then the machine on LAN2 can ping that machine on LAN until the connection times out. Is there any way I can make it so that that does not happen? I don't ever want any client on LAN2 to be able to ping or connect to any clients on any other interface at any time.

If I do not ping the client on LAN2 first, then it is blocked and working like it should.

On my old machine that has OPNsense 21.7.3 this does not happen.

Thank you!
