Firewall: FortiGate 60F
Firmware: 6.4.8 Build 1914 (GA)
Mode: NAT
NGFW Mode: Profile-based
Central SNAT: Enabled
Switches: S148FP
Switches Firmware: S148FP-v7.0.2-build0049
Issue: VLAN 30 (Workstations) cannot add a printer via TCPIP to VLAN 60 (Printers)
Firewall Policy is set to wide open for traffic to pass either way, but cannot connect any printer.
I have tried to use a NAT rule going both ways with no luck.
Also tried a multicast policy both way with no luck.
Been going back and fourth with a Fortinet tech but have gotten no where.
If more details are required, please let me know.
Any advise would be appreciated.

OK so that's a packet sniff output. Please go to that doc and do the steps in Step 4 which would be a flow trace.
Here's what it would look like:
diag debug enable
diagnose debug flow filter saddr 10.100.30.22
diagnose debug flow filter daddr 10.100.60.40
diag debug flow show iprope enable
diag debug flow trace start 100
diag debug enable
Please confirm source address (Saddr) and dest address (daddr) makes sense. daddr should be your printer.
After you've entered those commands, run an attempt to add the printer and paste the debug output.
Also of note, the output of the packet cap you pasted only shows SNMP traffic.

Looks like SNMP traffic is being sent by windows to determine if printer is offline. It also looks like your Central NAT is applying SNAT on the return traffic breaking the SNMP communication.
Can you post screen shot or output of your Central NAT config?
show firewall central-snat-map
config firewall central-snat-map

Can you do flow trace again but with the reverse saddr and daddrs? So:
diag debug enable
diagnose debug flow filter daddr 10.100.30.22
diagnose debug flow filter saddr 10.100.60.40
diag debug flow show iprope enable
diag debug flow trace start 100
diag debug enable

OK it seems windows is using SNMP to poll the printer to see if its online. The FGT is allowing this traffic. So we need to dig deeper to figure out what SNMP is saying and why windows thinks printer is offline.
Can you do a packet capture from the GUI with the appropriate filters for your workstation and printer IP only and UDP port 161. Start the packet cap, try and add the printer, then stop the packet cap and download the pcap and post it here please.

Please do it from the GUI and save the pcap as requested. I need to see the IP payload, not just the headers.
