I'd guess TEE would be the right place to look at since it creates another packet and sends it on. But beware, it's buggy in current kernels, a fix by Eric Dumazet is required: diff --git a/net/netfilter/xt_TEE.c b/net/netfilter/xt_TEE.c index ee2e5bc..bd93e51 100644 --- a/net/netfilter/xt_TEE.c +++ b/net/netfilter/xt_TEE.c @@ -70,6 +70,7 @@ tee_tg_route4(struct sk_buff *skb, const struct xt_tee_tginfo *info) fl4.daddr = info->gw.ip; fl4.flowi4_tos = RT_TOS(iph->tos); fl4.flowi4_scope = RT_SCOPE_UNIVERSE; + fl4.flowi4_flags = FLOWI_FLAG_KNOWN_NH; rt = ip_route_output_key(net, &fl4); if (IS_ERR(rt)) return false; Hope that helps, Torsten -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
