Hi, everyone, I'm find the ipchains not work , I
think is my fault , but don't know where I wrong sir..
My configuration is like that, I'm using Masq , and
now my other PC use internal IP to connect the redhat box with
adsl-line, and I wana to DENY outside people try to ping my host, is that
call ICMP ? and I before try a line like
that..
ipchains -A input -s echo-request -i ppp0 -j DENY
But after that I try to telnet another host and
ping myself redhat box, it STILL can ping and have response , so weired ?
thankyou your reply , sir /mardam
before the ( ipchains -A input -s
echo-request -i ppp0 -j DENY )
I also type "ipchains -L"
here is below I get the result..
