That's strange ... I have a simuilar setup on my router
which was upgraded from FreeBSD 6.x to 8.x recently.
I don't have any routing problems. So maybe it is a
problem with your configuration, not a FreeBSD bug.
My rc.conf contains:
ifconfig_fxp0="up"
ppp_enable="YES"
ppp_mode="ddial"
ppp_nat="YES"
ppp_profile="pppoe_myisp"
gateway_enable="YES"
And ppp.conf looks like this (few things omitted for brevity):
default:
set ifaddr 10.0.0.1/0 10.0.0.2/0
set server /var/run/ppp.ctl "" 0177
nat enable yes
pppoe_myisp:
set device PPPoE:fxp0
set authname myauthname
set authkey myauthkey
set dial
set login
add default HISADDR
enable dns
resolv readonly
The default route is set correctly:
$ route get default
route to: default
destination: default
mask: default
gateway: gateway.myisp.net
interface: tun0
flags: <UP,GATEWAY,DONE,STATIC>
recvpipe sendpipe ssthresh rtt,msec mtu weight expire
0 0 0 0 1492 1 0
Best regards
