A firewall is software that selectively inhibits communication. (1) Turn off the firewall, completely. (2) Test connectivity (3) If you can't connect, it isn't the firewall, its your network configuration. > > Here's what I tried with Debian 13: > 1. install from DVD > 2. go back to DVD, pull iptables .deb file (which the default install > didn't set up) off DVD > 3. install iptables (version number is 1.8.11, using nf_tables) > 4. fix sources.list so it points back to debian.org repositories > 5. go to out-of-date Ubuntu machine that can't safely connect to internet > since it's no longer supported, > run ufw enable, dump output of iptables-save and ip6tables-save in text > files (same version of iptables) > 6. use those text files on Debian machine as input to iptables-restore and > ip6tables-restore > 7. turn on wifi connection > 8.
