Setting up second wan connection.

I live in a remote area in broadband terms.  The service we now enjoy is beamed from the next hill and acceptable but we have no fall back connection.  I do however have an ADSL copper connection which is available from a different ISP. This has a much lower bandwidth but would be available as a fallback option should the wireless link fail.  Is there a wiki which would get me started with setting this up please.  I am using an SG135 UTM. 

I searched for a guide but didn't find what I needed.

Grateful for any pointers please.

  • It's easier than you expect:

    1. Connect to an unused NIC.
    2. Configure an interface with a default gateway on the NIC.
    3. Make a Multipath rule like 'Any -> Any -> Any : bind to original interface'.

  • Hi Bib,

    Found this answer and am working on it now.  Before I make a mess of things please could you clarify what you mean by "unused NIC"

    Could mean several things to me.

  • Hi Philipp,  Thanks for pointing this out to me but as I stated above I have no idea how this has been set up or when.  What is worse is that I have no idea if I need Web Filtering or on which interfaces.   What function do these serve?

    Why for example are Admin and Internal allowed and how are they defined.  I shall now look further into the machine but if there are any guidance notes please advise.

    Many thanks again,

    Alastair.

  • Hi Philipp,

    The Optional Interface you have highlighted is not visible on my device.

    I turned the Web Filtering off and the Uplink balancing still does not work.

    Is there a step by step guide on how to do this please?

  • Hi Alastair,

    In Web Filtering you can configure different Profiles so that traffic for different groups or internal LANs can be handled differently.  In order for WebAdmin to show the 'Optional interface for outgoing traffic' as suggested by Philipp, you must run the following command as root at the command line:

         cc set http enable_out_interface 1

    Cheers - Bob

  • Hi Bob, I am not having much success here.  The Web Filtering was a surprise as I had no idea it had been set.  I wonder if it came as a result of my setting something else.  

    Can I leave Web Filtering off while I try and sort out my second WAN connection?

    I tried this, as I said earlier, but even with Web Filtering turned off I still had no internet or email access as soon as I turned on the multipath rules and uplink balancing.  What next I ask?  

    With regard to Philipp's advice and your related help I note that if I access the UTM as root it negates any support available from Sophos.  Do I really have to go in using SSH. Surely it shouldn't be necessary for what I am trying to achieve?

  • Yes, it's not advised for people to start mucking around with things at the command line unless it's something known to be acceptable.  Sophos UTM: How to change the outgoing interface for Web Filtering gives more instruction than I did, but it clearly indicates that the command I give above is acceptable.

    How about a picture of your Multipath rules?

    Cheers - Bob

  • Hi Bob,

    If I try and set the GW on the second interface it automatically turns on the Uplink Balancing which calls a login popup and stops my WAN connection so I have not included the default GW on the AAISP interface.

    On the multipath rules there is only the one rule.

    I have set an arbitrary IP subnet for the AAISP interface.  I do not have the IP address of the router but can get it in the morning.

    I am having trouble inserting the file so see if it works:-

    file:///home/alastair/Pictures/Pictures.tar.gz

  • For reasons I don't understand I cannot insert my zipped screenshots this time.  I get a message saying the file or url is not allowed to be inserted!4667.Pictures.tar.gz

    But this seemed to work.

  • Sorry, Alastair, but I don't have a tool that lets me see those pics.  How about just jpegs or pngs?

    Cheers - Bob

  • Hi Bob,

    Ok I think my file was damaged.  Try this.

  • Hello Alastair,

    what makes me wonder here is your remark "it automatically turns on the Uplink Balancing which calls a login popup and stops my WAN connection". What do you mean by "login popup"?
    And, of course, the second GW forces uplink balancing to be enabled, that's by design.

    @Bob: I think we need to fix this "login popup" thing before we ca go any further here...
