Dynamic NAT with Overload command

virgoboy009 — Mon, 11 Mar 2019 20:51:57 GMT

Hello Guys,

Due to some reasons I am looking forward to use Dynamic Nat on a Router along with Overload command.

ip nat pool IZone 83.X.164.68 83.X.164.127 netmask 255.255.255.192

ip nat inside source list 100 pool IZone overload

access-list 100 permi ip 192.168.x.0 0.0.0.255 any

My query is that with this setup does Dynamic+Overload release pulic ip ranging from 83.x.164.68 to 126 then does PAT for the final IP

83.X.164.127 and is it possible to achive this?

When i see the output sh ip nat tran

i see that 83.X.164.68 single globa ip being used for more than 50 inside local subnet for nat translation

Thanks,

KA.

You need to create another pool with just that IP address(start and end) and overload that for the same source.

ip nat pool IZone-overload 83.X.164.127 83.X.164.127 netmask 255.255.255.192

ip nat inside source list 100 pool IZone-overload overload
