hiya people! im just wanting some advice on fiewwalls. i would like to set ufw to drop incoming contacts by default. but im not very bright - so between man ufw, and https://wiki.ubuntu.com/UbuntuFirewall, i think its a simple matter of typing
i would like to know is this right? and what are the rammifications of my doing this. will i still be able to brows the web with firefox, or will i accidentally cut myself off? if i accidentally cut myself off, will i have to give ufw specific instructions to allow firefox to connect to the web, then specific instructions to allow update manager to connect, and to allow synaptic, and so forth. and then if i do, how do i do that?Code:sudo ufw default deny
at the moment, ive got the firewall enabled, but its default policies are all accept (am i right), so enabling it is a little pointless.
oh - and im not using samba, nor wine, nor anything else like that. i would just like to know how to configure the firewall to aggressively block internet connections, while at the same time letting me choose who gets in or out.
hope its clear what i want to achieve!
thanks to anyone who's reading this!
