Ubuntu

since update no one can remote connect to me

Asked by Daniel Pantic

I apologize in advance ive never experinced this issue nore do i know which part of the system to look at to even try resolve this myself.

i updated from ubuntu 14.04 to 20.04 with heart ache to figiure out netplan to setup a static ip and a dhcp for my cable modem finally got thier all my rules were working correctly, did a apt-get upgrade and dist-upgrade as i had secirtiy updates, rebooted the server now i cant direct connect to none of my hosted servers in my local network and no one esle can remote connect it.

system was fresh installed 18 days ago (uprecord report) hosting my servers for 16 days without a glitch.

im sorry if this is vauge to my problem but i currently have no idea where to even look as normally my iptables fail when my wan is down.

Did you upgrade to 16.04 in between or did you wipe the 14.04 install off and do a clean install of 20.04?
