So sniff on your wan and try to go to www.googhe.com - do you see a syn go out?

Not at all. It seems the UDP traffic is routed via the RDP client via the local client connected. I see a lot of UDP back and forth to the external IP of the client machine

Its mega weird...

UDP ?
RDP ?

Where is google.com ? That one is TCP - and what has Google to do with RDP ?

Huh???

Here - I sniff on my wan for the www.google.com IP..

I then open a browser to https://www.google.com - and you see the SYN sent, and then syn,ack back and the conversation.

Cool_Corona

@johnpoz I see nothing to google.com in the packet captures....

Like in NOTHING. Despite typing www.google.com in the adress bar of the browser.

Locally I run the ASUS RTAX88U and pfsense runs on a server at the office and is accessed via RDP.

From pfsense do a traceroute to the www.google.com IP.

Are you tracing to the correct IP?

Your not showing the traceroute command.

So clearly you have a route - so why does your fetch say no route?

There is a piece to this puzzle that is missing - and once figure that out.. Its going to be a D'OH! moment..

I had a similar issue about couple of days ago but couldn’t find any issue with pfSense as I could do ping trace etc. It sorted itself out the next day.

I don’t think it’s a pfSense issue.

I have one of the VLANs setup for testing purposes bypassing Suricata and DNSBL. So I can test if there is any problem accessing websites (without upsetting my wife )

Hope it helps !

stephenw10

So to be clear you are RDPing to a machine at your office and testing from that machine?

That is where all your traceroutes pings etc are run? Not locally?

It did here also until it stopped again. I cant wrap ny head around it. Stopping and clearing Suricata blocks... stopping DNSBL and it still doesnt work

I got that.... its funny HAHAHAHAHA

rameshk

@cool_corona did you disable Suricata and pf blocker and restart pfSense.
Also try from a non Windows machine as windows machines can drive you crazy when testing something like this.

Cool_Corona

@rameshk I dont have any other than windows machines to test on.

I have rebooted, disabled, rebooted to no avail.

stephenw10

Still need to see exactly what's happening there.
Previously it looked like you could ping www.google.com but fetch returned 'no route to host' which seems impossible!
Try doing those things consecutively.

Steve

rameshk

@cool_corona Ohh that’s a shame. I use Ubuntu laptop for diagnostic purposes as it’s lot easier. Windows got their mindset and make life harder at times.

Did you check any other search engines I.e bing

Anything else than google.com works no issues.

Indeed it should be impossible but its apparently not.

@cool_corona
Please check DNSBL whitelist to see whether there is any entry for google.com

It looks like google.com is blocked somewhere unintentionally.

Packet capture and Wireshark are your friends. Keep us updated.

Wish you good luck.
