We are using a 2851 and using a VzB VOIP solution. In our other 8 centers we have a firewall performing the NAT but this was the first center to go live so we did the NAT on the router.
These NATs are for our VOIP phones. 10.41.4.5 is one of the phones. This phone needs to be NATd in order for it to work however in order to connect to our NTP server it needs to keep its original address.
I am currently NATing all outbound traffic behind my Multilink123 interface. However when I try to access an internal device the addresses are still being NATed. How can I create an ACL not to NAT my internal traffic?
Here is a copy of my config:
ip nat inside source list 98 interface...
one other trick is if you know the ip address...ping the ip address and then do a show arp...this displays the mac address..then you can do what jdeisenm says to do...
Unfortunately thats not the case in my situation...I have six switches in one general area that are upliked off of one an other and 2 that are connected via a fiber uplink...
Is there a way to look at the interfaces on the LAN ports to make sure that there aren't any speed and duplex mis matches?
Any information would be greatly appreciated.
thanks!

I have a user that is now working from home. Her extension is 3116. She wants to keep her extension pointing to her voicemail but I have someone sitting at her desk. How do I keep 3116 but change the extension at the desk to another extension without affecting the 3116 extension.
thanks
