Problems configuring both static and dynamic NAT translations

Hi there,

I have a router 4700 with a fastethernet interface (LAN) and a serial interface with leased line to our HeadOffice. Everybody that go outside the LAN has to make NAT. I have configured dynamic NAT with a pool "ip nat pool p50200 10.99.101.1 10.99.101.255 netmask 255.255.255.0" but I have to configure static NAT for some addresses "10.99.101.101, 10.99.101.181, 10.99.101.208". The problem is that the NAT translation for "10.99.101.101, 10.99.101.181, 10.99.101.208" are duplicated.

I Know that the global addresses use in static translations are not automatically excluded with dynamic pools containing those global addresses but I don?t know how exclude that addresses from the pool.

Thank for your help.

Bye

Re: Problems configuring both static and dynamic NAT translation

Hello,

you cannot really exclude single IP addresses from a pool. If possible, try and configure the range of to-be-excluded IP addresses at the beginning, such as in this example:

ip nat pool p50200 10.99.101.11 10.99.101.254 netmask 255.255.255.0

This would leave addresses 10.99.101.1 thru 10.99.101.10 for static translations...

Regards,

GNT
