Brian,
I will begin drafting a novice-level wiki page about firewalling, basic
security, various tools available (e.g. iptables, fail2ban, port
knocking, etc.). I'll attempt to parse the Archives for comments
regarding security matters, device configuration considerations, route
tables, firewalling, etc. that have been helpful security practices
amongst those in AMPRNet.
Thanks,
- Lynwood
