I just looked at my routing table, and the route pppd created does not
have the "G" flag like I'm used to, is there a reason for this?
PPP is Peer to Peer Protocol. Ie, it is from one peer to another. It has
nothing whatsoever to do with gateways, etc.
Now you CAN use the peer as your gateway if you wish, but there is no need
to.
In your output the default route is delivered to the ppp interface and
since there is only one thing, the remote peer, connected to that
interface, all traffic is sent out to that remote peer.
A gateway says "if you get traffic for this range of addresses send it to
this IP". In your case it says "In the default case just dump it onto the
ppp interface"
This is output from route:
# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.64.64.64 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 br0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
It seems to work, I'm just wondering why? And can it affect something
in the future?
