changed port config, can't connect via WebAdmin

BJohnson

I fear that my issue will result in a reset, but wanted to warn everyone else.

BE VERY CAREFUL when changing port configurations on the SG115w.  I wanted to change the 2 LAN-side ports (eth0 and eth2) to 1000Full with no HA, change the WAN port to 100Full with HA, and the HA port (eth3) to a second, strictly-backup WAN port with Auto-duplex and HA.  Unfortunately, I confused eth0 with eth1, so I changed eth1 to 1000Full with no HA and I changed eth0 to 100Full with HA.

Now, the only port that responds when I connect an ethernet cable is eth1, but I cannot connect to WebAdmin via browser.  When I connect directly to the device via VGA monitor and USB keyboard, it tells me to connect to WebAdmin via the LAN IP of the device, but when I connect to the device via ethernet cable, my browser always times out when attempting to connect to WebAdmin.

Is there a way for me to get back into the device, or am I stuck redoing my entire configuration?

And shouldn't this be just a little harder to do?

Thanks in advance for responding.

    Not sure if you have turn on the SSH access. If not, try this method to have root access to the device https://www.sophos.com/en-us/support/knowledgebase/115346.aspx

    Then log in via CC 

    root#cc

    127.0.0.1 MAIN >RAW 
    127.0.0.1 RAW >lock_override
    127.0.0.1 RAW >OBJS

    127.0.0.1 OBJS > itfhw 

    127.0.0.1 OBJS itfhw > ethernet

    127.0.0.1 OBJS itfhw ethernet > REF_Itf    If you hit 'tab' you will see the list of active interfaces.

    Example : On the eth1 change to auto-negotiate or hardware setting according to your requirement.

    127.0.0.1 OBJS itfhw ethernet [REF_ItfEthEth1IntelCorpo] >auto_negotiation=1  

    127.0.0.1 OBJS itfhw ethernet [REF_ItfEthEth1IntelCorpo] > w   

    It might require reboot for the changes to take affect.

    Hope it helps.

    Thanks!  I ended up loading a configuration file onto a blank usb stick, and rebooting the UTM with the stick connected.  The UTM automatically loaded the config file on the stick.
