Hello everyone.

I have an omada stack

ER605 -> TL-SG2210P -> EAP610 (PARENT) ---> EAP610 (CHILED Meshed)

            -> OC200

I've been configuring a Guest VLAN with a subnet of 192.168.250.1/24 and a IoT VLAN with a subnet of 192.168.25.1/24

Now, i have a rasberryPi that is running CUPS in the 192.168.25.1/24 network

Those clients in the Guest VLAN cannot print any document.

Now, clients in Guest VLAN can ping the rasberryPI's ipaddress so ICMP seems to work. 

its just that they cannot print anything.

However, if the client switchs from GUEST Vlan towards the same VLAN as the IoT

client can print successfully, this means same network printing is OKAY

Based on the CUPS documentation, it runs on TCP/UDP 631

I've check via wireshark TCP ports 631 and it seems that i can't get ACK

it is always retransmitting

I've set some switch ACL (like allowing IP-Port Group TCP/UDP 631 on SRC and DST) but it seems that it don't do a thing. 

Right now i've deleted all ACLs that i have from Gateway to EAP, still it won't print (i've read that by default, all traffic from all vlans are allowed)

still not working .

Anyone can advice me on this.

Thanks
