Sophos Xg 115 rev 3

misabih

Hi, this is my first time installing pfsense. I installed the software on a sophos xg 115 rev 3 just yesterday. When I reached the assign interface stage I get the usual four ports igb0-4.
I automatically assigned wan which it detected. And LAN i had to assign manually and I did it to all 3 remaining as I figured that was the way. The problem i have now is no internet for starters and I do not know which port is wan and which is lan. I looked up online and nothing does make sense to me as I'm not very tech savvy. If anyone could help me figure this out it would be great. Thank you.

@misabih since you got the device it's up to you to test it, documented it and let us know. Connect a cable to a switch and to a port and check with eg `ifconfig <interface>' for the field 'status: active'. If no link is detected then 'status: no carrier' is shown.

 igb0       igb1    igb2    igb3    igb0 (again)

And maybe it's similar to the 105: XG105rev3 numbering explained

Yup you can confirm it at the console. Drop to the command line using option 8 at the menu then enter ifconfig.

That will show you which NICs are linked. So if you connect only one port you will be able to see which NIC that is.

For example on this box only the WAN is connected:
