PPPOE broken after 405-5 update

StefBezuidenhout

Hi all,

I've just updated my UTM home to 405-5. Everything was working before but now, after the restart my external interface is down and I have no internet access. Using a Windows PC directly plugged in front of the UTM, PPPOE works perfectly so I know my account and link is working. I've also tested with a hardware modem/router. Account and ISP side is fine but the UTM fails to bring up the external PPPOE interface. All I see in the PPPOE log is this:

Any ideas anyone?

    Hi Stef,

    Can you please verify the configuration for PPPoE in UTM before we proceed further. Please refer https://community.sophos.com/kb/en-us/119003

    The default MTU value of 1492 is required for DSL connections. It may be appropriate to change this if connecting to ISPs that require smaller MTU values. Can you also verify this from the ISP end if we require changing the MTU value as per the requirement?

    Thanks

    Thanks. I did check those things. Config looks like this (creds removed):

    1492 is what my ISP gave me. As I have mentioned it has been working for months with this config.

    Hello Stef
    Just updated to 9.405. PPOE Config. is similar to yours, only "Static PPOE IP" is checked; maybe you can try with your old IP.

    Thanks Peter,

    Yeah not sure what is going on. At the moment I have a semi working solution. I've placed an old hardware router in front of UTM and it just does the PPPOE. All ports are forwarded to the WAN ip of my UTM. This in essence means I'm now double natting which isn't great but since I'm not doing PPPOE with UTM its working. I cant really try the static IP thing you suggested since my ISP doesnt give me a static IP. I have to get it via DHCP. I am starting to think I should build myself a test XG firewall this weekend and see if that can do PPPOE. If it does work I may just be forced to make the switch. I have heard mixed reviews about XG but I may be forced into it.
