my internet connection in some sort of lock down mode

[Just_Client]

I was trying to get help from service and after waiting for a half an hour just decided to post problem here, with hope it will be picked up by service people.

I suddenly got a huge problems with my internet at home.

All my networking programs stopped working after recent update to my router.
After some checks it appeared that network is blocking all network ports except a small number of services like port 80 or 443.
Everything else is blocked.
Network applications one by one stopping to work completely.
All my networking programs which were working OK for a year, all went Red and failing to make connections.
I have problems with connecting to my work using VPN and it is even getting worse by the day.
Some websites became blocked today and were working even yesterday.
As far as I can tell, my internet connection in some sort of lock down mode at the moment.
I do have Unlimited Fibre 65 plan - which I completely unable to use at the moment.
Looking at logs, I see that this service cut off happened somewhere 5th of June.

Does anybody have similar problems or can guide me were to raise this issue?

As I can't get to service desk.

Hello,

Could you try factory resetting the router and then re-setting this up again to see how this compares please.

Thanks

I forgot to mention, that I did setup DMZ on the router to see if it will help to expose computer to Internet without any router firewall involved. 

Basically everything left the same, just couple more ports became open for communication. Namely 30000 and 30100.

Hi Debbie.

No I did not reset my router, but I did unplug from power it for a moment and switched on again - all problems were the same.

I did not understand what is going on and was assuming that something wrong with programs I use or even my computer setup.

However, after I managed to get VPN up - all failed progrms started to work.

Proving that it is network filtering/blocking.

I also can tell now, that I started to have issues maybe couple months ago in some limited areas.

For example I even raised service ticket with my VPN provider after suddenly I was unable to use UDP protocol for VPN connections.

As I see it now, that was early manifestation of coming big today's problem.

Should I try router reset to factory settings?

Hi Just_Client

Thank you. Can I just check, have you also tried factory resetting the router using the pin hole reset for ten seconds?

I guess I made it.

I meant I did update the profile.
