Potential regex bug with IPv4 Bogon parsing

[skaag]

We received a complaint from another ISP claiming we were blocking their range. The range in question is 185.149.252.0/22.

A look at the Firewall logs revealed a surprise: it was being blocked because it was on the list of Bogon networks. I couldn't believe it so I looked at the list of Bogons myself but I couldn't find a CIDR that would match. I'm referring to the list that pfSense updates from, found here:

https://files.pfsense.org/lists/fullbogons-ipv4.txt

I had to temporarily disable Bogon filtering in the Rules section, to allow this ISP's customers to reach machines behind our firewall.

Is this a bug in how pfSense Bogons are parsed? There's a range in there that's close: 185.1.128.0/17
Is it possible a parsing bug associates the ISP's range with this Bogon network above?

I didn't want to submit a full bug report before confirming it here first, on the forum.

Thanks!

I don't see how that could happen if you go under diag, tables you can look at the bogon table - what is in there?  I don't see this 185.149  - you sure that was his IP he was coming from?  You saw it in the logs for blocked bogons?

Your local copy of that file may be out of date. Check Diagnostics > Tables, and pick bogons there. Click the update button to refresh your local copy.
