DHCP issues on External Interface with ISP

I have been using UTM for many years now... 6+?  When I first started, there were issues with certain Intel nics when used with DHCP and Cable Modems.

Lately, I have been having problems again.  I have had MANY calls with my ISP, I even went ahead and bought new hardware for my UTM.  Same problem.  I rarely get an IP address from my ISP and when I do, the external interface will only stay "up" for a brief period - and then drop again.

I plugged my "Gateway desktop" directly into my Cable Modem and it ran without an issue for 3 days.  Then I added an ASUS RT-N66 in as a "router".  That ran fine for a week - with A LOT of traffic going through it. 

I add the UTM and BAM!  I am back down again.

My question is - WHERE do I begin to troubleshoot this?  confd logs?  TCPDUMP?  My UTM seems happy to get a DCHP address from my ASUS if I test it that way...  I don't want to bail on Sophos, but I don't know what else to do.  Many years ago, I put an old router between my Cable Modem and my Sophos machine.  I really don't want to do that again.

UTM 9.355-1       

External NIC is an Intel Gigabit PCIe   EXPI9301CT

Quad core i3 with 4GB RAM, 160 GB HDD

  • What model cable modem are you using and how fast is your internet service?

  • What's in the DHCP log? 

    What kind of interface type is it? Can you post a screenshot of it.

    tcpdump would be a good place to start. Do it on the WAN interface for ports 67 and 68. 

  • My modem is an Arris TG862G/CT.  I typically get 60mb down and 6mb up. 

  • The only DHCP logs I see are for the DHCP service (unless the client logs there too... I will check. 

    Also - I just saw the ethtool command... I will post the settings shortly.

  • One thing strange I see here is the MDI-X is set to ON.  I am NOT using a cross-over cable.  I forced it off, with no change.

    gateway:/root # ethtool eth1
    Settings for eth1:
            Supported ports: [ TP ]
            Supported link modes:   10baseT/Half 10baseT/Full
                                    100baseT/Half 100baseT/Full
                                    1000baseT/Full
            Supported pause frame use: No
            Supports auto-negotiation: Yes
            Advertised link modes:  10baseT/Half 10baseT/Full
                                    100baseT/Half 100baseT/Full
                                    1000baseT/Full
            Advertised pause frame use: No
            Advertised auto-negotiation: Yes
            Speed: 1000Mb/s
            Duplex: Full
            Port: Twisted Pair

                                   drv probe link
            Link detected: yes

  • That's a very reliable modem. I have noticed similar issues with my Xbox One. For some reason it doesn't like to auto negotiate the port speed while it's sleeping. I would try modifying the UTM interface hardware settings for that particular port to a fixed 100baseT-Full and see if that helps. You should reboot both devices after making the change so they both recognize the new speed.

  • Can I do that through the webadmin console or do I have to use the ethtool?  My understanding is that if I use the ethtool, it would not be persistent unless I modified a startup file or network config file somewhere.  Attached is my Interfaces page from Webadmin.

  • From that screen just click the Hardware tab... It's the very last tab on the Interfaces menu. Clear the auto negotiate box and then a drop down will appear.
  • OK - tried that.  Still no-go.  I also turned off the HA link option since this is only one node.  I did find a few interesting entries in the system messages and configuration daemon logs (I will insert here.)  Is there a way to insert the logs?  It looks like I just have to paste them into this window..
