HI. Well wouldn't say an expert but I do use iptables for my firewalls. Their are other things you can use. Some of which are an easier front end to iptables itself. UFW uncomplicated firewall for ubuntu. Shorewall is another where you define zones. A lot of the documentation out there on the web about iptables is old or inaccurate. For example. I remember reading somewhere that the default policy in iptables input chain is drop. Not so as you can see with the command. iptables -L INPUT I prefer to use iptables as it's explicit what you're doing. Anyway what specifically are you trying to do? My advice would be as for most tests, do it with vms first. And always add a rule allowing established connections and ssh from your own machine first.

Hello,
If we have any iptables experts please contact me privately. I am not and I can not wrap my head around iptables, I am trying to do two adjustments to a raspberry pi firewall (without breaking anything), and wanting to add two features.
Help appreciated.
Thanks. Dave. _______________________________________________ Blind-sysadmins mailing list -- blind-sysadmins@lists.hodgsonfamily.org To unsubscribe send an email to blind-sysadmins-leave@lists.hodgsonfamily.org
