I don't know. This is ISP controlled device. To make insult worse it used to work with OpenBSD pppoe (no custom kernel), until it stopped (maybe ISP didn't want to present device IP to the client ?). I had to learn why it stopped and then I found out about Bug in sppp regarding remote IPCP negotiation endless loop. > > # /etc/hostname.pppoe0 > inet 0.0.0.0 255.255.255.255 NONE pppoedev vr0 authproto chap \ > authname 'some-customer-id-here' authkey 'secret-key' \ > description "pppoe uplink" up > dest 0.0.0.1 > !route -nq add default -ifp \$if 0.0.0.1 So with in another reply I found out that I can set remote IP to pppoe and it seems to be working. Here is my working for now config for /etc/hostname.pppoe0 inet 0.0.0.0 255.255.255.255 10.64.64.33 \ pppoedev em0 authproto chap \ authname 'testcaller' authkey 'secret' up !/sbin/route add default -ifp pppoe0 10.64.64.33 This allows me to assign bogus IP for ISP pppoe device (10.64.64.33) and default routing rule so I can forward packets. Although the remote IP is bogus so packets with IP dest 10.64.64.33 won't be replied by ISP pppoe device, but I don't have need for that. I just need to forward my packets to the internet. > > I don't remember any issues with above setup and that OpenBSD > machine was running -current and was rebooted many times during > its 6+ years of service.

Hope it makes more sense now. Thanks for the help. -- -- Best Regards Krzysztof Kanas
