Country Blocking Not Working for a WAN > LAN Rule

Timothy Stewart

Hi.  It seems like country blocking is not working for WAN -> LAN (or any other protected network behind XG Firewall).

I have tested this with a proxy in the blocked countries.

I have this rule at the top of the list and network traffic still passes even though the rule shouldn't allow it, basically ignoring it.  The rule is never triggered thus always stating in 0 B, out 0 B.  I have tried every combination of Source/Destination/Zone/Network and still it doesn't work.

    I have read through this thread and forgive me if I missed it, but it wasn't clear to me whether or not this is a confirmed bug in the XG or not?  I've seen some various workarounds offered (thanks for those) but has Sophos confirmed this is a bug?  If they say its not a bug (I have no idea how that could be true) is there a feature request somewhere we can upvote?

    No, this issue has not been recognized here by anyone from Sophos.  It is also still missing from the known issues list.

    In his post on page 2, Aditya Patel demonstrated that the IP to country mappings are working correctly (which had already been proven in this thread).  But there has been no other information about the actual issue that blocking by source country in a Network Rule is broken in XG.

    , how is the status of Country blocking?

    It simply does not work on Wan to LAN Firewall rules. This is a bug and it is not even tracked. Users cannot use this features.

    Can you update us? We expect to see Reference NC soon.

    Thanks

    Hi

    I can see this thread has gone on for a while and there has been a lot of confusion.

    The issue that Aditya referenced above (NC-17519) relates to incorrect classification of IP address to country definition in certain cases, so I don't think that directly relates to the original issue in this thread. E.g Country blocking WAN to LAN simply not working at all.

    I'll try and setup some tests here to test this behaviour, as it isn't something i have come across before, and update you.

    In the meantime, if anyone has anyone support case references where this has been raised or "NC-" reference numbers that they have been given by Sophos Support in relation to these symptoms can you private message them to me?

    Thanks

    Hi All,

    I can confirm that this is something that has been logged and the intention is to change how this behaves in v17 MR1. The reference for this change is NC-17413 in case anyone needs an update on the release version from Support.

    Interestingly, the root cause of this isn't specifically connected to country blocking itself, but is more related to the way that zones work internally in relation to DNAT and business application rules. I'll spare you the technical details, but suffice to say the plan is to change how this works so that it aligns more with how one would expect the configured ruleset to behave.

    In the meantime, IP based access to a given DNAT can be controlled either within the DNAT rule itself, or by placing another DNAT rule above it to blackhole the traffic as already mentioned in this thread.

    , 

    thanks for your reply and info. What is strage and unacceptable is that Sophos took more than one year to give us an official answer and a NC number.

    This should never happen!

    Many users have forgotten this feature or even explained to customers that the feature Country Blocking is half working (not in all area).

    Really disappointing thing![:@]

    Hi Luk,

    I agree this thread has become a little confused with discussion of the IP classifications which hasn't helped the communication, which is why i wanted to try and clear this up.

    The advice we would always give to get an official answer on potential bugs or changes to the product is to log a case with Sophos Support, they will then be able to provide the correct information along with the reference IDs where applicable. I can see support cases have been logged for this particular issue and the correct information provided to the customers logging those cases, but that hasn't filtered down to this thread.

    This thread was brought to my attention via a support case that was logged earlier this week.

    By the way, on an unrelated note, thanks for all the posts and information you contribute on this forum, it is appreciated.

    Hi Luk,

    As Greg mentioned, the issue is not completely related to the Country Blocking module but it affects the discussed feature. I understand your concern towards the delay in creating the NC-ID but looking at the issue there was a working work around to blackhole the IP addresses and meanwhile, there were a lot of bug fixes during this time. Please be asure that we are continuously working on the XG firewall and  the accountability of bug fixes are considered on the basis of the criticality of the issue. 

    Thanks

    Silence and sometime in the future are quite different period of time and they have different meaning. If there is SW code there are bugs and no one complains on that. What we are not happy and really angry here is the silence for a long time and then...pooof someone from Sophos reported the NC and gave even an expected release version.

    So be sure to properly report time and NC most efficently here and to all users. Another issue that is around the forum are bookmarks. There is an NC number but it does not cover all issues (I guess).

    Taking a year to have an answer is more than alot. Be sure to at least inform as that it is a bug, your are investigating, or whatever phases you are but the silence is the worse phase users accept.

    Silence means poor quality!

    Kind Regards

    We understand the concerns but the NC-# was not created until v16-MR1 and the JIRA was not directly referenced to the country blocking issue, which is one of the reason my team was not sure to reference it. We were already discussing this internally but we were not able to get a solid case reference on this issue. The cases were mostly resolved configuring a blackhole business rule and it is an accepted solution as we see. 

    We work as a tangant team between the Support and a Customer hence we can only report and expidite the NC-# if they are already created & reported but we cannot emphasize on creating one of the NC#. The reason we were not able to provide an update on this issue is because, the workaround was accepted and the cases were never reported in the escalations or went cold. 

    I will take the responsibilities of such unresolved thread, please PM me and I will make sure they are immediately looked upon by us and the support team. 

    Sincerely,

    Hi.  I created the original issue and I want to make sure it is not getting diluted with other issues and workarounds.  The issue still stands.  My steps to reproduce are in the first post.  A workaround of a blackhole is just that, a workaround and not a fix.  Will this issue be fixed?  Is it being address?  The feature clearly does not work.
