Hi Vadim, =20 I don't quite understand your question. =20 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. =20 This ppp bug appears to be uncovered by the arp-v2 changes, however, I was informed another thread on net@ also raised a ppp issue of similar erroneous behavior in 7.x. =20 So if I remember correctly, the problem you've reported is a different issue. I had to fix the kernel code. =20 -- Qing ________________________________ From: owner-freebsd-current@freebsd.org on behalf of Vadim Goncharov Sent: Mon 12/29/2008 5:24 AM To: freebsd-current@freebsd.org Subject: Re: NAT (ipfw/natd) broken in latest -CURRENT Hi Li, Qing!
