Sonicwall Block Bank Terminal

HCECENES_93

Good afternoon.

I am posting this thread because I have a situation with a Bank Terminal, it cannot connect to its server through ethernet and wifi.

I tested with other network without a Sonicwall and it works.

Could you please help me with a procedure to allow this connection?

I will appreciate your response.

Hi

Ensure there is an access-rule allowing the traffic between the terminal server zone and the server zone.

I think there is no need for a NAT rule since its an internal banking traffic.

You can monitor the passing traffic through the connections logs or packet-monitor

if you have SSO Service activated. Check that the CardTerminal is allowed to reach WAN without SSO Authentication.

In DPISSL Service "contentFilter" you should allow Banking.

also an exclusion for the https certificate of the Banking Website / CardTerminal manufactorer Website could be helpful.
