TZ 270 blocks Triumph-Adler Cockpit
I use a TZ 270 and a printer from Triumph-Adler with a hardware device to send actual information about the printer as toner status. The traffic works over a xml-based interface with port 443.
Since I implement the firewall, the connection between the data center of TA and the hardware device does not work correctly. In consultation with Triumph-Adler, they told me, that Sonicwall is rated TA not correctly and I must redirect the traffic in the firewall.
In the access rules from LAN to WAN all Ports are open and I added also a NAT Rule, but still not working.
With the old TZ300 all works fine without configure any policies.
Does anyone have an idea, what the problem can be?
Thanks for the help.
