For example, from the router itself, I send a packet to destination 1.1.1.1:1000. I need the dnat to change that destination to 1.1.1.1:2000 as it leaves the router.
Dstnat seems to only work on incoming traffic. Is there something I can do to force it to go through dstnat before it leaves?
it seem imposible, since the dst-nat located on prerouting. But, if this could be done, it would be usefull. in example i would like to make several pptp connection to the same server with difference out interface.
