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 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...

  • Thanks, Alastair, that helps.  I don't think this will work if the AAISP interface doesn't have a default gateway.

    Agreed, Philipp, that confused me, too...

    Cheers - Bob

  • Hi Bob & Philipp,

    Sorry for the long pause.  We have guest occupying the room and I have to wait until he leaves and I can access the AAISP router.  Hope will get there this evening and check out the AAISP connection and router settings.  I thought AAISP could access from their end but couldn't.  More fun later!!!

  • OK, I have checked out my other broadband connection with AAISP.  The connection is up and working.  The router lan port is configured as a normal access port with DHCP and default GW and I can connect to it with laptop and browse.  All OK so far.

    On the UTM I have set up a dedicated access port, port 1 on its own subnet with unique IP/25 addresses and it is connected to the AAISP lan port. 

    The problem is when I try and set the default GW for port 1 on the UTM, things go wrong.  As soon as I do this I get the warning that uplink balancing is required and is enabled.  I then get a link error on the AAISP.  

    If I try and cinnect to a website using a Firefox browser I then get an Warning:Potetntial Security Risk from Firefox with the message.  See screenshot and note the Network management prompt in the corner.  Unfortunately this also took me off line so I have to back out to be able to send this which may be why the screenshot appeared above!!!

    Grateful for what to try next.

  • That PC needs to have the Proxy CA from the UTM installed on it, Alaatair.  You can download that in WebAdmin or via the User Portal.  With a second WAN connection, you want Uplink Balancing enabled.

    Cheers - Bob

  • Hi Bob,

    As usual I am finding this hard going.  I was able to select the button on WebAdmin and download the certificate to my laptop.  I was then able to go into Firefox an upload the certificate using settings security pages in Firefox. To be sure I rebooted but sadly when I then enabled the default GW on the AAISP port and the load balancing clicked in, I still could not access a website.   This really shouldn't be this hard.  Where next?

  • "Uplink" balancing is different from "load" balancing.  The latter applies to inbound traffic that's load-balanced between two or more servers.

    Show a few lines from the Web Filtering log where the traffic is blocked.

  • Bob I mistyped.  I was referring to Uplink balancing.

    I shall gladly share a few lines from the Web Filtering log when I know where to find them and copy them.  All new stuff to me I regret. 

  • Hi Bob,

    Had to leave the second connection mid thread while trying to keep business running.  Should have finished it as now I need the fallback connection to work and it doesn't.  Please could I resume on this thread or should I start over. 

    Regards,

  • Hi Bob,

    Just wanted to apologise to you for making such a meal of this and to thank you for your help.

    My problems were due to lack of know how on my part and a mis-configured router thanks to ISP.

    With some additional help from Dirk and some time on phone with ISP I now have the basics sorted out and have two WAN connections.  I therefore am closing this thread and thanks again,

    Budge
