I too am using 255.255.255.0, and have set the netmask option in ppp -- and
even though it doesn't seem to have any effect shown in the routing table,
it seems to be working:
redhat 5.2 (kernel 2.036, pppd 2.3.5, pptpd 0.91)
server 10.0.1.1/24
local ip 10.0.1.2
remote ips 10.0.1.3-10
Client Win95 w/MSDUN1.3:
I connect and receive ip 10.0.1.3 (255.0.0.0 in routing table), yet I can
ping another host on the internal network (say 10.0.1.11/24) with no
problems. Traceroute shows hop of 10.0.1.2. (from the other direction,
traceroute shows hop of 10.0.1.1).
Of course, if you have another internal 10.x.x.x network, then you have a
problem.
