Sophos UTM and BT Infinity Static IP Range

BigRich100
Does anyone have any experience of getting a UTM box working correctly with a BT Business Infinity service (with 5 IP addresses). 

I have already got the service connected and working correctly using the external interface configured using PPPoE but I can't get any config to pick up my external IP's to static NAT through to some internal devices. I understand that BT uses some WAN IP aliasing but no idea whether this translates to what Sophos call Masquerading or whatever.

Any guidance gratefully received as I've been banging my head against the virtual wall on this one for hours.

Thanks in advance,
Richard

    Hi, Richard, and welcome to the User BB!

    You need to use the 'Additional Addresses' tab and what I call Rule #4:

    When creating DNATs for traffic arriving from the internet, in "Going to:" always use the
    "(Address)" object created by WebAdmin when the interface or the Additional Address was defined.
    Using a regular Host object will cause the DNAT to fail as the packets won't qualify for the traffic selector.


    Cheers - Bob
