Any known issues with Sonic wall TZ400

Just replaced Cisco 891 VPN router with Sonic wall

DHCP scope setup for With enable DHCP conflict detection enabled.

Customer has very old printers Tally line printers with network cards using 9100 TCP

192.168.212 and 213

Since connecting sonic wall, the printer intermittently go offline. Reset printers and they are back up for about 30 minutes then off line again. we can still ping printer but unable to telnet port 9100 when its in this state/

Software customer uses running on OLD AIX system, so not sure if the conflict it there as this is where the printers are install

Swore it wasn't the sonic wall, but customer overnight, just plugged Cisco back in, and sure enough all day printers have been fine.

Any thoughts or idea appreciated

    Create Static ARP entry for those printers and try.

    What else is in the topology of this network (switch, hub, anything)? Did anything else change besides the firewall? Are you using other interfaces / sub-interfaces / subnets on the Sonicwall? Do you have a copy of the config of the Cisco to compare?

    The fact that you can still ping them but cannot telnet to them is interesting. But is this pinging from the AIX system that prints to them or from a different device? If the AIX is the only thing that prints to them then something is going on with communication between only those devices, which brings me back to my first question...

    Also, to answer the question posed in the title of the thread: look at firmware release notes for known issues.
