I have a SonicWall TZ100, firmware SonicOS Enhanced 5.8.1.13, with a static subnet of 10.0.6.0/24
on X0
. Ports X2-X4
are port shielded to X0
. On ports X3
and X4
I have two devices that were moved from different locations and we forgot to update their settings while on site. Their IPs are 192.168.213.254
and 10.0.4.253
. I'm not sure which one is connected to which port.
What do I have to do on the SonicWall to gain access to the web interfaces of those devices so I can change their IPs? I don't have physical access to the devices which is why I'm trying to do this remotely.
I tried assigning the X3
and X4
ports with static IPs of what the gateways for those devices should be, but it didn't help so I reverted it back. Help would be appreciated.

I'd approach this in a totally different way: Configure a PC (laptop) with 3 IP addresses: 192.168.213.250 and 10.0.4.250 and an address on the new subnet. connect the two devices and the laptop on the same VLAN. (no firewall, just (an isolated) hub/switch or direct connect cable) just connect to the old IP adres and start reconfiguring.
Then change your laptop back to DHCP client.
In cases where I don't even know the IP address of the network device, I connect directly with wireshark capturing with an arp filter. Most of the time, the device does an gratious arp, and then you know the IP.
