RE: NAT (ipfw/natd) broken in latest -CURRENT

Hi Vadim,
 
I don't quite understand your question.
 
The ppp route insertion code always set the RTF_GATEWAY flag
regardless whether the gateway information is present.
I fixed the code such that the RTF_GATEWAY is set only if
gateway is given.
 
This ppp bug appears to be uncovered by the arp-v2 changes, however,
I was informed another thread on net_at_ also raised a ppp issue
of similar erroneous behavior in 7.x.
 
So if I remember correctly, the problem you've reported is
a different issue. I had to fix the kernel code.

Will it break again all the NAT-PMP using programs which need to determine
IP-address of default gateway? Currently it works with mpd, which sets default
gateway to correct IP, not an interface or self route.
