Adding another NIC to XG home

I have a simple XG Home setup with 1 LAN and 1 WAN card.  I wanted to add another NIC for a separate LAN zone.  Seems simple right?  I added the card and the entire system stopped working.  My previous WAN card began getting a DHCP address from the LAN (not from the cable modem).  Seems like the order of the cards determines which card is the LAN and which is the WAN.  Since I put the new card in slot 2 (original LAN slot 1, original WAN slot 4), it appeared as if the new card became the WAN.  I wonder if slot 1 is always the default LAN and the card in the second position is always the default WAN?  I removed the card and everything works properly.  In the Console, LAN is listed in slot 1 and WAN in slot 2.  Thoughts?

Thx

Rick

  • Hi Rick,

    when you add or remove a card the XG does strange things, but never allows the re-assignment of interfaces automatically as the UTM does. I am stuck with a dual NIC I no longer need because the backups assign it to a physical not logical and ig the physical card are missing then nothing works.

    The only way is a fresh install and then a fresh configuration from my experience. Painful. The LAN/WAN assignment is what you configure at install time.

  • Thx for the reply.  I have confirmed that your observations are correct.  I thought that I had made sense of which card should be LAN, WAN etc whent the new card was added and adjusted the cables accordingly.  Wrong.  Nothing works when the new card is added.  I can't even communicated with the device.  Switch cables to all possible configurations...no go.  Removed the card and back to normal.  Disappointing.  The take home message is to plan for expansion during the original build.

  • I believe it would work in a way that at the time of installation add maximum NICs and use as per the requirement.
