Country vs Registered country

Am I understanding the things properly ?
If your understanding is that geoip info is changing target and no db is going to be 100% accurate then yeah your understanding it correct ;)
But sure in such a scenario as your example it would be better to use the country vs registered - but does every IP in the db provide this info? I would think not.. But maybe @BBcan177 could make some adjustments to use country if provided?

Conclusion: pfBlockerNG is using the "registered_country" to authorize countries but should use "country" which reflects in a more reliable way the country where the IP is used ... not the country where the IP was purchased ...
But what happens if company XYZ buys a block of address space and uses some of it elsewhere, Maxmind don't know what's used where ?

Not right away that is for sure - we sold off some of our /16 space while back, and it was now being used in the middle east vs the US.. And it did take a while for that info to get updated. To be honest I would have to check - maybe its still wrong ;)

Indeed I used to work for a company that had xx.0.0.0/8 and now some of it is used by Microsoft.

@nogbadthebad I just checked, and the first range that was sold is updated to the new company and country looks correct from what I remember being told where the IPs were going to be used just in conversation when the sale was taking place.
But it was sold if in multiple different size blocks, so would have to check some other ranges to see if they are all up to date.
While in general - I think a really good attempt is made to be correct.. But there are always going to be inconsistencies to be found

Now on my pfblockerNG, as I said I blocked the whole world by doing "Deny both" on absolutely all the 9 lines in GeoIP summary and then I unchecked just France + France_rep (in Europa) and USA + USA_rep (in North America) to allow these 2 countries ... result is weird: without my VPN I can access my server behind the firewall, if I activate my VPN, I cannot access anything if I choose a french location, a US location, a swiss location but if I choose the irish location, I am back accessing the server ...
Don't block the whole world using pfBlocker alias, create a rule to deny all and above create a rule to allow what you want using a pfBlocker alias.
If you deny all with a pfblocker alias you'll have a massive alias that every packet will need to traverse.

Hello,
Well it seems that Maxmind does know pretty well, I tested a lot of the IP's provided by the Mulvad VPN and Maxmind is always returning the proper "country" (ie "country" shows the country where Mulvad pretends to be for that IP and a site like iplocation.net does as well), but Maxmind does also return the "registered_country" which seems to be where the IP was originaly purchased and there is also (but not always) a "represented_country" (used when the IP address belongs to something like a military base) ...
But to summarize, I think that pfBlockerNG should use "country" and not "registered_country" to reflect where the IP is really used. In my case I had to authorize "Sweden" to be able to use an IP used in Zürich Switzerland.Pierre.

@pierr0t Care to share a few of the ip addresses you checked against?
-
For example the one I am currently using, Mulvad VPN Zürich Switzerland, this is the answer from GeoLite:
curl -u "xxxxxxx:xxxxxxxxx" \ "https://geolite.info/geoip/v2.1/country/193.32.127.221?pretty" { "continent": { "code": "EU", "geoname_id": 6255148, "names": { "ru": "Европа", "zh-CN": "欧洲", "de": "Europa", "en": "Europe", "es": "Europa", "fr": "Europe", "ja": "ヨーロッパ", "pt-BR": "Europa" } }, "country": { "iso_code": "CH", "geoname_id": 2658434, "names": { "pt-BR": "Suíça", "ru": "Швейцария", "zh-CN": "瑞士", "de": "Schweiz", "en": "Switzerland", "es": "Suiza", "fr": "Suisse", "ja": "スイス連邦" } }, "registered_country": { "is_in_european_union": true, "iso_code": "SE", "geoname_id": 2661886, "names": { "ja": "スウェーデン王国", "pt-BR": "Suécia", "ru": "Швеция", "zh-CN": "瑞典", "de": "Schweden", "en": "Sweden", "es": "Suecia", "fr": "Suède" } }, "traits": { "ip_address": "193.32.127.221", "network": "193.32.127.0/24" } }%Mulvad tells me I am in Switzerland but I have to authorize Sweden to go through pfBlockerNG :-)

Regarding this specific remark (about denying all and just authorizing specific country): I know, I just have to do it ... but it's a very low traffic firewall so I'm in no hurry ...

The whois reports Services AB infrastructure in Zurich, Switzerland and the IP/ASN reports ESAB-AS, SE.
When you do the AS number it reports 193.32.127.0/24 as belonging to ESAB-AS, SE to the right.
Looks to me like its a Swedish company hosting a server in Switzerland.
-
Yes exactly, IP is being used in Switzerland but was purchased in Sweden (Mulvad being a swedish company).
Maxmind reports it properly, the question is how does pBlockerNG use that info, for me it should use the "country" info instead of the "registered_country" info ... but I guess that only the author of pfBlockerNG could tell me if my diagnostic is true or not.

@pierr0t If BBCan177 doesn't find this thread you could create a bug/feature request at redmine.pfsense.org. If it's not a bug, possibly it could be added as a separate list like "rep" is separate, although it would basically double the size of the existing "all IPs in ___" list if they are listed twice and people allow two. A bit more flexible but more confusing.
IOW does the Swedish company just happen to put their servers in a data center in Switzerland and they are using it? Is a particular block from an ISP that works across borders? Many possibilities.
Allowing your own IP is a bit easier...can be done for one, if you create a dynamic DNS hostname and allow the hostname.
-
@nogbadthebad You could maybe use the providers ASN number, they only use 4 providers in Switzerland:-
-
Yes but at the same time, it's not really me, it's pfBlockerNG ... I understand I could create rules using the ASN but if I use pfBlockerNG it would be nice if they were using "country" instead of "registered_country" ... Anyway I will try to open a feature request/bug as suggested by @SteveITS :-)
Thks.

Interesting, yes that would allow me to use all Mulvad's IP's to go through the firewall, thanks.
I did a feature request here: https://redmine.pfsense.org/issues/14324
