Hello,

I am new to networking. My setup is like this:

ISP Modem > ER605 > SG2218P > SG108E (this is where I am connected)

Vlans are: 50, 68, 69, 99, 101, 102. SG108E is at my office and my PC is on PORT 2 untagged for VLAN 99. My NAS is on PORT 4 untagged for VLAN 50.

My router came in with firmware "Build 20220106". BEFORE I upgrade it to "Build 20240718" my ACL rule seemed to work. Unless there was some kind of a cache thing. I was on port 5 at first that is again for VLAN 50. I deleted the rule, upgraded and remake it. But now, it doesn't work. I google, it said I should make an opposite rule for DENY 50 to 99. I did it. Nothing!

Any ideas? Please guys. Pitch anything.
