Iptables
Hola, estoy intentado aprender a configurar iptables y creo que por fin
he conseguido activar las opciones del kernel necesarias pa que
funcione. La he puesto como módulo y cuando ejecuto un 'iptables -L' pa
ver las reglas que tengo me da el siguiente mensaje:
/lib/modules/2.4.19/kernel/net/ipv4/netfilter/ip_tables.o: unresolved
symbol nf_unregister_sockopt
/lib/modules/2.4.19/kernel/net/ipv4/netfilter/ip_tables.o: unresolved
symbol nf_register_sockopt
/lib/modules/2.4.19/kernel/net/ipv4/netfilter/ip_tables.o: insmod
/lib/modules/2.4.19/kernel/net/ipv4/netfilter/ip_tables.o failed
/lib/modules/2.4.19/kernel/net/ipv4/netfilter/ip_tables.o: insmod
ip_tables failed
iptables v1.2.6a: can't initialize iptables table `filter': iptables
who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Parece ser que falla el módulo aunque no tengo ni idea de por qué. La
versión del kernel, como veis es la 2.4.19. Puede ser que aún me falte
alguna opción del kernel por activar?? Tengo activadas las siguientes:
