Yeah, seems like the registration to IPinfo is required so that you can download a token which then allow pfBlockerNG to download the ASN database. I’ve just registered to IPinfo and it seems like (unless its a false alarm) that it now works.

However, I’ve also learned that all the ARUB ASNs I had didn’t include the SMPTS server I was using.

Basically, I did an nslookup smtps.aruba.it, got the IP and then did a search for the ASN using Team Cymru IP to ASN Lookup v1.0 here asn.cymru.com/cgi-bin/whois.cgi to find the ASN. I then copied the ASN in the WAN_EGRESS list and bingo its working.
