Try looking in the state table for what is associated with this IP address. (Diagnostics / States / States)
I will be more and more curious....

With the settings discussed, the dnsleak test should show something like this....

The only difference between the DNS settings of our systems is that I perform DNS queries through a VPN tunnel. (ExpressVPN)
since the datacenter is two blocks away from me and both the Cloudflare and VPN provider ping times are 2 to 4 ms (therefore, DNS over VPN also provides very good speed)

BTW, Do you have a VPN?

cburbs

No VPN here just trying to tweak my Pfsense box as a starting point. Lock things down better.

Also Do you have any rules under firewal/rules/wan?

Yeeeepppp is actually the box for that.

to your previous question: Also Do you have any rules under firewal/rules/wan?

I don't like to load the WAN side with rules, it's like drilling a hole in a sieve, pfSense block all unsolicited traffic on the WAN, so I have more floating rules

@DaddyGo

I have a WAN rule called - Easy Rule: Passed from Firewall log view - says it was created by Easy Rule .

Trying to figure out what it is -
Protocol: IPv4 TCP
Source: ISP IP addres
Destination: 104.25.242.31
Port: 80(HTTP)

Destination IP is Carrier: cloudflare

Confused?

Easy Rule

Yes it is, :-).
did you add it this? with this? (https://docs.netgate.com/pfsense/en/latest/firewall/adding-rules-with-easyrule.html)

cburbs

It has a date from almost a year ago. Could have as I think that is when I was looking at snort but was having all sorts of issues so I disabled it all.

So I probably don't need that rule - I won't do anything with it now but remove it later today.

cburbs

Do you use squidguard on your system? That was the next thing I was going to implement.

squidguard

I use HA proxy I think for my purposes more appropriate, Squid is problematic among MITM, so SquidGuard doesn't work for me either
But I strongly recommend installing Suricata/Snort and pfblockerNG-devel

DaddyGo

Delete the rule for said http 80 port because it is unnecessary!
I didn’t investigate all the way through, but it points to a Cloudflare CDN

cburbs

Yeah snort and pfblocker are on my list. I played with these a while back but it broke many things and haven't got back to them.

Before you jumping into these IPS / IDS, DNSBL, etc. things, I highly recommend Bill Meeks (alias: bmeeks) posts Snort / ÍSuricata and BBcan177 on the topic of pfblockerng
