no no no ... it shouldnt be invalid. a single jump rule with no other specifiers (in-interface, out-interface, ips, etc should all be blank) and jump to chain=ppp. It has always been this way, even in 2.9. The dynamic jumps are placed in the ppp chain then and are used.
Well, it's invalid until the PPP user connects, then it becomes valid and applies the rules appropriately. It would be nice if it were valid at all times..
ah ... i think thats why ive seen a blank passthru rule at the top in the hotspot on the custom chains... can you enter a passthru rule with a comment and have it always be valid ?
