>Description:
Although there is no ability to see IP firewall rules set up using
FreeBSD 'standard' ipfw package, alternate firewall toolkit -- ipf -- doesn't
honor jail security: ipfstat -io/ipnat -l works fine even inside jail.
>How-To-Repeat:
1) Set up any jail:
mkdir /usr/jail
cd /usr/src
make buildworld
make DESTDIR=/usr/jail installworld
cd etc
make DESTDIR=/usr/jail distribution
2) Run shell inside jail:
jail /usr/jail localhost 127.0.0.1 /bin/tcsh
3) Start 'ipfstat' command:
ipfstat -io
And you will see all of your IP filter rules set up outside jail.
