Hi! I'm using netfilter (PREROUTING chain) on my router for redirecting all the trafic passing through designated to certain port to a local port on my router.
I'm interested in getting the original dest. address (adress before DNAT) from my server (which listens on local port on the router). I see there is a /proc/net/ip_conntrack file which shows connections active on the machine, but I wonder is there easier way of getting that information other than parsing that file? Which would be the easyest way to do this?
