SONICWALL MAC ADDRESS LOOKUP SERIAL
SONICWALL MAC ADDRESS LOOKUP MAC

I was troubleshooting for a while and those addresses kept appearing until GVC. And as SOON as I exited the Global VPN client she got an IP address.

SONICWALL MAC ADDRESS LOOKUP MAC

And that's when it hit me, could the Sonicwall Global VPN client be causing these weird MAC address issues? Sure enough her Sonicwall Global VPN Client was running still. I let her know something was weird on the network so she couldn't get an IP address (after clearing BAD_ADDRESS') and she casually mentioned she was on the VPN last night. The culprit turned out to be the Sonicwall Global VPN Client! A user could not get an IP address on the LAN but her WiFi luckily had a super slow connection so she complained.

It was not a rogue device on the network. I found the computer that was causing the problem so I was able to troubleshoot why it was doing this today. The good thing - I finally found the cause of this today. I looked into blocking by the mac address of the device but it doesnt look like the SSL VPN uses the mac address for connectivity. I thought about blocking by IP address but both locations have dynamic IP addresses from the ISP. Of course this does not explain what is happening but it lets us know it's not random so probably not some bad hardware device. I want to allow the desktop in the remote office access and block access to the desktop in their home. If you convert the rest of the numbers in the bad MAC address you will see it is simply the bad IP address backwards (in HEX). You will see that is the last number in the actual IP address. E.g., first bad address the first two digits of the MAC address is 27. The IEEE OUI and Companyid Assignments searchable database may be used to locate the manufacturers of Ethernet devices.

The SonicWall's MAC address is its serial number. The second half is used to identify the device itself.

To give an idea of what that incorrect MAC is simply take the first two digits in a HEX calculator and convert to decimal. The first half of the MAC address, the Organization Unique Identifier (OUI), identifies the manufacturer of the device. So in case anyone is having this weird problem with inaccurate MACs that have that weird ascending order.

Have you added any Wireless Controllers, or Access Points? Have you deployed any new Switches or Firewalls.ДЎ.Make sure you have only one DHCP in the network and the DHCP server is not running on a multihomed computer.Дў.During the troubleshooting process, disable the DHCP fail-over and make the scope available on one Server only to isolate the perception of DHCP Fail-over or multiple DHCP Servers issue.Д¤.Use some tools such as Wireshark to capture Live Network Data and analyze the process of Ip address distribution.
