iptables is targeted towards system administrators. openSUSE users should use the Yast Firewall module to configure and control the firewall.
To verify the version of the firewall, perform the following from the terminal.
/usr/sbin/iptables --version iptables v22.214.171.124
To manually update the firewall, visit netfilter.org and download iptables. Verify the signature or checksum, unpack the package, read INSTALL, and then perform the following steps listed below:
Configure using a standard account. Since setting up iptables only requires reading source files and invoking tools, a standard account is adequate and there is no need to log in as Root. Note that the iptables default prefix is /usr/local, which is a different path than used by openSUSE.
cd iptables-126.96.36.199/ configure --prefix=/usr
Make using a standard account.
Root and directory change
Acquire administrative privileges and then change directory into the package directory used to build iptables.
su - password: # cd iptables-188.8.131.52/

# /sbin/rcSuSEfirewall2 stop Shutting down the Firewall done
Install the new firewall.
# make install
