cisco 827h OT

IF you've got a subnet dedicated to the boxen behind the router, then you
will need to completely disable NAT (ip aliasing, masqurading etc.). NAT of
any sort will prevent external routing of the addresses. Also, check the
routing tables of the router. make sure the packets for the /28 mask network
are sent to the correct interface. Can the router see both networks?

| Hi all,
| I know this is way OT, but I have a cisco 827h router at work for which we
| have just allocated /28 network for the inside. now I have had telstra add
us
| into the tables. now I have set up an internal box with one of the IP's
alon
| with the ethernet interface on the router with one as well. I cannot
access
| any services of the internal network server, such as mail, or the web
| server... when I do a traceroute on the internal server, it stops at the
| outside interface on the router, saying it has completed, no time outs...
| when I ping a valid internal IP it says the address comming back is the
one
| of the external interface on the router, obviousely if I try to ping a non
| valid IP on our network I get the 100% packet loss.
|
| Would this have anything to do with NAT? or is there something else I need
to
| do, as I no longer need NAT, if they are non private IP's.
|
| cheers
