Sigh, okay I am trying XG again...

I have it installed, and I *think* I have some things configured correctly.  I have been running this only a couple of days, and that is longer than any time before.  ;)  So, there is some hope still of me keeping this (long time UTM user - old dog, new tricks issues).

I do have some questions and concerns about XG:

- Why are we not allowed to edit the Exceptions lists that are built-in?  Microsoft Updates are disabled by default in exceptions, and Office Updates are being blocked by default.  That's a bit concerning to me.

- Rules and Policies are still an absolute mess to me, but the Assistant does help a little bit (a lot) with this.  Thank you for that tool built-in.

- I do a lot of gaming and I am used to having to open ports to make things work.  I have yet to open a gaming port after being on XG - how is that possible?  And, adding a custom port to open (HomeAssistant) was painful to get right.  Does XG 'just know' what to block here?  This is my big concern with this: A rogue PC/device/etc on the local LAN transmitting out to a site.  It seems pretty solid for anything incoming, but outgoing I question.  Perhaps I don't understand the behavior of XG in how it handles outbound traffic, but at first look it feels like everything is open and you have to close everything up, completely contradictory to what it's always been.

- I have an extremely large list of web ad URLs.  It appears that the only thing I can use to add this for filtering is creating categories and applying them to be blocked in my policy.  The issue I have with this is that I am only allowed 2,000 entries per category, so this isn't an effective method of blocking ads.  I had to create seven categories and add them to a policy to filter out some ads (aside from any other filtering going on).  I could have just set this up completely wrong, but was the only thing I saw where I could import text files.

- Is there going to be any kind of allowed modifications to change the display such as the connection list?  I have a 4k monitor with a 3840 resolution.  Everything I have to scroll through to be able to see everything even with this large of a resolution because these lists don't adapt to screen sizes.

I have more, but I can make another post or reply later on.  I'm sure   will hate me being here (ha!) as I am pretty critical of this software and keeping them on their toes.  I really do want to like it and use it but I have no time for boxing matches with software, and if it's not for me then so be it.  I'll give it a fair try this time (I've only been able to stomach this software in the past for only about four hours before I went back to UTM).

  • Hi Amodin,

    easy bit first, the GUI display is an ongoing issue and usually get raised during each EAP.

    Next, the block advertisement using web and application policies does block most ads at least  on my system, What you can't block are the inbuilt ads to a web page, but when you click on them they are then blocked. To use the web and application policies fully you need to enable IPS rules eg LAN to WAN or one of the less strict default versions. Enable Applications even if just allow all at this stage and the same with the WEB policy. I do suggest you use the web proxy until you are more comfortable with the XG behaviour. SSL/TLS does not scan UDP in the current version of XG.

    The XG allows ports that you have enabled for your rules then opens other ports as requested by the connection, this is a function of stateful inspection design firewalls, these are closed at the end of the connection.

    The MS exception list is a bit out of date and you can add to some of the existing policies by cloning a copy and add your extras.

    Mo firewall will stop a rogue device from transmitting to the internet, but how much and where it connects to are dependent on how tight your firewall rules are. Most games will require some open rules with no scanning.

    Please feel free to ask if I have missed much.

    The XG has a default allow firewall rule from Lan, any host, to WAN. I think that is pretty similar to the default UTM allow rule of

    Internal-->ANY service-->External. but you are right in that it will allow everything outbound and you should delete that rule and only allow the essential services to get you started like HTTPS/HTTP/NTP/DNS/Up2Date outgoing and then add rules for any other services outgoing you need. 

    It seems like a pain trying to add all those web ad URLs. I looked into AdGuard home DNS which links your devices to ad guard's cloud DNS service to let you choose adblocking lists just like the browser add-ons, but it's all done from their DNS servers. That way you'll not have to worry about importing all those lists.

  • Hi,

    there are a couple of documents in the recommended reads at the top of the forum that might help you 7nderstand some of your issues.

    Yes I see that now as I was reading the replies - thanks for that.

    Good to know, and as Alan pointed out I have an edit to make. ;) As for the office updates, I planned on just cloning and modifying my own to fit, I was really just curious why none of the ones built-in on the installation were not accessible to edit. 

    Mo firewall will stop a rogue device from transmitting to the internet, but how much and where it connects to are dependent on how tight your firewall rules are.

    My big concern here is really about my cameras - most want to make that connection to the outside for whatever reason and do their thing.  I don't like that, and I shut them down with rules. That's about the only rogue device I anticipate on my network, as we are pretty aware what happens here.  You never know what will happen though and I again defer to Alan's (now obvious mention) rule modifications.

    Thanks all.  Slight smile

  • Yeah I am looking through them as I go.  The Assistant really has been helpful as well.  I don't believe that was in there the last time I had XG loaded.  I do need to find Country Blocking though, that's a must for me, lol.

  • I have country blocks at the top of my rule lists, only works for outgoing on most sites. My cameras are only allowed to talk to the camera companies cloud server using specific ports.

  • Does this look correct to block outbound traffic to certain countries?  I want to make sure I understand the Rule structure correctly:

  • I wonder if you could create a null IP address outside of the DHCP range, and point your camera's settings to use this "blackhole" in a destination NAT rule.

    The other option is a firewall rule blocking the camera from connecting outbound which would work as usual.

  • Your country blocking rule looks good, it need to be in position 1.

  • Yeah I thought about that, and they oddly enough use a 169.x address when they transmit.  They don't use my assigned IP, which irks me, but the 9999 port they use gets them every time.
