Dotaz: Presmerovavani - iptables

[pdp7]

Pri presmerovavani pomoci iptables dostavam

iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Prosim poradte.

Nejspis to nebude zakompilovany v kernelu (pouzivam vlastni jadro, gentoo). Mohl by mi tu nekdo poradit jak se tam ta polozka jmenuje a kde ji najdu?

[krab1k]

Mělo by to být Networking - Networking options - Network packet filtering - IP Netfilter configuration - IP tables support -Full NAT . Jinak taky CONFIG_NF_NAT. BTW: Při make menuconfig lze vyhledávat pomocí "/".

Mam to nastaveny takhle

#
# IP: Netfilter Configuration
#
CONFIG_IP_NF_QUEUE=y
CONFIG_IP_NF_IPTABLES=y
# CONFIG_IP_NF_MATCH_IPRANGE is not set
# CONFIG_IP_NF_MATCH_TOS is not set
# CONFIG_IP_NF_MATCH_RECENT is not set
# CONFIG_IP_NF_MATCH_ECN is not set
# CONFIG_IP_NF_MATCH_AH is not set
# CONFIG_IP_NF_MATCH_TTL is not set
# CONFIG_IP_NF_MATCH_OWNER is not set
# CONFIG_IP_NF_MATCH_ADDRTYPE is not set
# CONFIG_IP_NF_FILTER is not set
# CONFIG_IP_NF_TARGET_LOG is not set
# CONFIG_IP_NF_TARGET_ULOG is not set
# CONFIG_IP_NF_TARGET_TCPMSS is not set
# CONFIG_IP_NF_MANGLE is not set
# CONFIG_IP_NF_RAW is not set
# CONFIG_IP_NF_ARPTABLES is not set

NAT tam nevidim.

Networking
  Networking options
    Network packet filtering framework (Netfilter)
