Hi,
I'm connecting via PPPoE to my ISP (SBC).
I've a static IP /29 assigned to me (x.x.x.232 - x.x.x.239).
To 'get at' (for firewalling, etc, eventually) all the static IPs,
I've setup in-kernel PPPoE to negotiate the connection through
an ADSL mode config'd in bridge-mode.
I'm confused about assigning NETMASKs.
I'm making my primary ppp connection at interface
ppp0, IP address = x.x.x.238
and setting up interface aliases of,
ppp0:1, IP address = x.x.x.233
ppp0:2, IP address = x.x.x.234
ppp0:3, IP address = x.x.x.235
ppp0:4, IP address = x.x.x.236
ppp0:5, IP address = x.x.x.237
using an intfc cloning range defined in
"/etc/sysconfig/network-systems/ifcfg-ppp0-range0"
I plan to handle each interface ppp0 + ppp0:1-5 separately in my firewall.
Questions:
What should be the NETMASK for the primary 'ppp0'? /29 or /32?
And for each of the aliases?
If the right answer if ppp0 -> /29, & ppp0:# -> /32, should I ALSO
create an alias ppp0:6, IP address = x.x.x.238 (same as ppp0 !?) but
with a /32?
Thanks.
Geri :-)
