By 'card', do you mean the lwIP device? And what do you exactly mean with "the 
router don't see" that card? Do you have a small broadband router an wonder why 
it doesn't list the lwIP device under it's active network devices in it's web 
server? If so, that's probably a limitation of the router (in that it only 
shows the DHCP addresses which it assigned to devices) and there's probably 
nothing you can do about it.

I don't know why you need the router to "see" the device (if I understood you 
correctly, see above). As long as you've got the routes set up correctly (or 
for a broadband connection at home, set up NAT or port-forwarding correctly), 
the router should just pass on packets, no mater if it "sees" a device or not.

Calling dhcp_inform() will probably not help you there and doesn't sound like 
the correct thing to do...
