        Carrier Grade NAT is security for people who carry things uphill.

              @catsalad@infosec.exchange that's why i have triple NAT ​​

              CG-NAT
              NAT in the shitty ISP modem/router
              NAT in my own router

              no way to open up ports anyway on this ISP anyway so i'm not really losing anything

                      @dazo@infosec.exchange @catsalad@infosec.exchange indeed, i forward my server's ssh port to a vps using autossh so i can easily log in remotely and access everything on the lan from there

                      i don't mind accessing things in an ad hoc manner so i haven't bothered with a full vpn yet

                          @ij @catsalad actually... recent advances in processing has made double ROT13 trivially defeatable. NIST now recommends quadruple ROT13.

                                    @chronovore You know... the 13 in ROT13 stands for v1, 3rd grade encryption. So the improved version is v2, 6th grade encryption, hence: ROT26 of the Rorschach-Ohm-Tyson algorithm...
