<div class="moz-cite-prefix">Hi All<br>
<br>
Thanks for the help so far - it's now at the point where I feel
like this needs to go on-list though.<br>
<br>
The other's have so far helped me determine what the following
line of config is supposed to achieve:<br>
<br>
ip nat inside source static tcp PRIVATEADDRESS PRIVATEPORT
PUBLICADDRESS PUBLICPORT route-map AAPT extendable<br>
<br>
My initial question was what does the route-map statement achieve?
I have never seen it put at the end of a "port-forward" before.<br>
<br>
In this case, that route-map matches against a specific WAN
interface, and an ACL that lists a whole bunch of private-subnets
as sources to "any". It was explained to me that it's likely to be
some form of destination based NAT but it has us a little stumped
still. However the route-map actually does not look like it was
designed specifically for this translation at all and is used in
other contexts through-out the configuration.<br>
<br>
Normally I would drop the topic here, re-do the config my way and
be done with it. However, apparently Cisco TAC made this
configuration and I'm not too keen on assuming they've done
something wrong.<br>
<br>
My question is - at what point would a dedicated WAN interface see
(legitimate) inbound packets sourced from a private subnet? Can
anyone shed a little light on what this may possibly be trying to
achieve? I am limited in the configuration examples that I can
give so apologies in advance.<br>
<br>
Thanks<br>

Looking for someone to ping me off-list - just need some quick
assistance / QA with some Cisco NAT / route-map config, have
found some config which I can't find any documented examples
of and I'm not entirely sure what it's achieving.<br>
<br>
Thanks in advance<br>
