I'm working with a customer who has a camera system installed by a different vendor and it's configured for remote viewing. Unfortunately, this is causing the customer (a retail store) to fail their PCI compliance scan due to open ports.
My suggestion was to purchase a second static IP from their WAN vendor (Verizon FiOS) and use 2 routers: one for their POS system (an existing SonicWall) and a new router for their WiFi and camera access. So the system would look like this:
Verizon FiOS ONT Box
HP 1810-8g Switch
The problem is that when I connect the SonicWall through the HP switch, the WAN port won't connect. When I set a laptop to the same static IP and plug in it to the same switch port on the HP, it connects fine and is able to pass data. As soon as I connect the SonicWall directly to the FiOS ONT, it works fine.
Here are a few more specifics:
SonicWall MTU: 1492
HP MTU: Default (1500?)
HP Switch: No VLANs set; LLDP disabled; jumbo frames off; port mirroring off; flow control off; green features off; loop protection off; advanced security off; no trunks configured; management port set to Port 8 on an unused subnet
Any help would be great. Thanks.
