Hi Christopher.
Thanks for the prompt reply. I have tried and have not been able to print across VLANs without enabling Inter-VLAN routing on both source and client networks. Can you please step me through your recommendation for enabling TCP 631 and UDP 5353 ports after disabling Inter-VLAN routing? My expertise is limited here and I don’t understand how this would work.
Just to reiterate my earlier post, Dowling’s 2017 instructions (12427) enable Inter-VLAN routing and then employs firewall rules to restrict all outbound and internal traffic on the printer VLAN. When these rules are in place, the printer VLAN has no access to the Internet nor can the printer VLAN access my untagged VLAN. I don’t know the intricacies of Inter-VLAN routing and Layer 3 protocol on the Peplink router as it relates to security in general and firewall rules in particular.
Thanks, Christopher.
