Lost access/ internet after creating a bridge

Hi,

what sort of hardware are you using? Is port 4 configured for access? Do you have a backup of the configuration before you changed the interfaces configuration?

Ian

I am using old Sophos firewall XG 135 appliance. I don't have the latest backup, but I have something that is good enough for it to work. So does that mean load backup? 

I don't understand what configured for access means, therefore, most likely not :-) Port 4 originally unbound, so as the rest, except for 1, 2 & 3. 

Hi.

if you can't access the device you can't load the backup. I was asking if port 4 was configured for any form of access.

You can perform a hardware reset and then load the backup.

Saw that I can by plugging usb in and have backup renamed as restore.abf? Or can't I?

Hi  jang430 

Try to access the firewall with WAN IP and enable appliance access from console this might help to revert back the changes 

enable it with the following command.

system appliance_access show

system appliance_access enable

system appliance_access disable

Regards

Thank you. I will keep that in mind in case I attempt again :-) already initiated reset to factory default.

Hi  jang430 

if you want a redundant connection between your switches, try to set up a LAG instead of a bridge.

Use a different, unused network range on the interfaces instead of using the same one.
