PortForward con ipchains e kernel 2.4.18
ciao,
devo semplicemente forwardare (brutto) su 192.168.1.101:25 e 110 le richieste che pervengono
dall'IP pubblico.
INTERNET--->Firewall debian---->mail server
come si fa?
ho provato con
# iptables -t nat -A PREROUTING -p tcp -dport 110 -1 eth0 -j DNAT --to-destination 192.168.1.101:110
..ma mi da questo errore:
/lib/modules/2.4.18/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy
/lib/modules/2.4.18/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.18/kernel/net/ipv4/netfilter/ip_tables.o failed
/lib/modules/2.4.18/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed
iptables v1.2.6a: can't initialize iptables table `nat': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

come faccio a fare il PortFW sotto kernel 2.4.x compilato per ipchains?
ciao,
