Hi!
I have question about iptables:
If I want to block e.g. telnet for my two ippp-devices I do it this way (this works very good :)):
iptables -A INPUT -i ippp0 -p tcp --dport 23 -j DROP iptables -A INPUT -i ippp1 -p tcp --dport 23 -j DROP
So my question: Is there a way that I don't need to write a rule for every single interface?
why don't you try: iptables -A INPUT -p tcp --dport 23 -j DROP AFAIK its not necessary to specify an interface.
Something like "iptables -A INPUT -i ippp0,ippp1 -p tcp --dport 23 -j DROP" (I know this does not work)
