PCI Compliance failed UDP port 500


#1

Hello Everyone,

I have a customer that has a Peplink Balance One running FW 7.1.0 Build 3433. Just recently they started failing PCI compliance and the results were stating because UDP port 500 was open relating to remote desktop. After taking a look I showed that I had remote user access turned on using L2TP with IPsec. I turned it off and the PCI scan then started passing. However, the user needs this remote user access turned on to get access to the network remotely. Is there by chance an updated firmware that fixes this issue?

Hello jondjr,

UDP 500 and 4500 are common port when IPsec is being used. This port being open is expected.
