Unexpected Connection Time Outs
Hello everybody. I have these experience frequently with pfSense of having connection timed outs to specific websites. Most 99% of the websites works normally but specifically connecting to Google's classroom.google.com produces unexpected connection time outs.. Sometimes its good, sometimes not..
I have nothing installed but pfBlocker and Snort and it works perfectly.. Just that for a some reason, pfSense is having its days... What would the problem be?
If you test without Snort or pfBlocker does it still happen?
Otherwise check the list of usual suspects here:
Yes it does still happen even if Snort and pfBlocker disabled/uninstalled. The only way around it is to reboot. But this is quite a disruption.
I checked all the usual suspects and (probably) could not find any. As I can access those timed out website normally using a different connection (mobile).
Ok, you need to see what's actually failing there. If there is nothing logged as blocked you may need to catch it failing in a packet capture. Once it fails does it stay failed for a bit? Something that might be easy to capture?
Seems like I figured it out. It was not a problem on my side but the ISP. I was running the WAN in bridged mode PPPoE and seems like my ISP is picky about MTU since we have a business(school) plan. Was running it at pfSense default. And changed now to what my ISP pref.... Weird thing, but well. it's ok now..

Unless you set the MTU larger than expected, it wouldn't make a difference. You can smaller and it will only affect throughput. So, I assume you set it too big.
