Title: default deny rule blocking traffic accross bridge
Post by: commissar0617 on August 09, 2021, 02:16:08 pm

so, i have my WAP connected to my firewall so i can filter traffic from the vlans in it. vlan 1 is on a bridge with lan, no vlan. they're both the same subnet,a nd DHCP is handled by my DC.

i was able to connect to the WAP just yesterday, but im unable to connect now today, despite not making changes. firewall logs show traffic to/from the wap being blocked by the default deny rule,  despite having explicit blanket allows on the bridge in firewall.

Did you set the necessary tunables as documented here in step six?

Not quite - the fact that you need to explicitly enable the interfaces is documented here:
