 |
|
I'm trying to forward port 80 to 8080, but whenever I try I get:
| Code: | iptables -t nat -A PREROUTING -i $WANIF -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables: No chain/target/match by that name. |
However, it does not seem to be a problem with the nat table as this gives no errors:
| Code: | iptables -t nat -A PREROUTING -j ACCEPT
|

Well, then it's the REDIRECT target?

| But what is wrong with it? All references and guides I find seem to advice the above. Is there a kernel option which have to be enabled for redirect? |

| Code: | $ zgrep REDIRECT /proc/config.gz
CONFIG_NETFILTER_XT_TARGET_REDIRECT=y
CONFIG_IP_NF_TARGET_REDIRECT=y
CONFIG_BRIDGE_EBT_REDIRECT=y |

Thanks. In which kernel were these introduced? It seems like my kernel is too old as I don't have any options named REDIR. |

IP_NF_TARGET_REDIRECT was in the kernel at least since 2005.

| Yep, that was the problem. The option was not enabled in the kernel. Works now. Thanks! |
