You need to recompile your kernel -- do you have the source code installed for your kernel?

First you could check whether the feature isn't enabled already.

Try 'zcat /proc/config.gz | grep <the feature>'

oh, dear, it sounds very scary for the newbie i am... i don't know if i have the source code. how can i check it?
in case it means anything, i'm using kanotix64 (based on knoppix).

abisko00:
i'm afraid i can't understand the answers
do you think you could please be so kind as to tell me whether it's ok or not?

For Linux 2.6.x: You must enable (as a module "M" or compiled-in "Y") the following features in your kernel:

"Device Drivers / Networking support / Universal TUN/TAP device driver support" (CONFIG_TUN)
CONFIG_TUN=m
CONFIG_TUNER_3036=m

"Device Drivers / Networking support / Networking Options / Network Packet Filtering (replaces ipchains) / IP: Netfilter Configuration / Connection tracking (required for masq/NAT)" (CONFIG_IP_NF_CONNTRACK)
CONFIG_IP_NF_CONNTRACK=m
CONFIG_IP_NF_CONNTRACK_MARK=y

"Device Drivers / Networking support / Networking Options / Network Packet Filtering (replaces ipchains) / IP: Netfilter Configuration / IP tables support (required for filtering/masq/NAT)" (CONFIG_IP_NF_IPTABLES)
CONFIG_IP_NF_IPTABLES=m

"Device Drivers / Networking support / Networking Options / Network Packet Filtering (replaces ipchains) / IP: Netfilter Configuration / MASQUERADE target support" (CONFIG_IP_NF_MASQUERADE)
for this one, it doesn't say anything. just shows the prompt in a new line.

is it so that all the features except for the last one are enabled?

Is seems you understood very well

Indeed, all features seem to be enabled in your kernel, which means you don't need to re-compile the kernel. The last feature may be called differently. On my system, I have CONFIG_IP_NF_TARGET_MASQUERADE=m. If a feature is not set, the configuration usually says so: e.g. # CONFIG_REISERFS_CHECK is not set. The complete missing of this feature indicates that the name has changed.
