[cisco-bba] 7204vxr - IP NAT multiple inside global

[Vaibhav Bagaria]

Hi Nathan,

This link should help you with using pools for a range of public IPs.

http://www.freeccnaworkbook.com/workbooks/ccna/configuring-a-network-address-translation-nat-pool

I have had thousands of sessions terminate on 7201s before but it didn't include NAT and the total throughput was under 500M.

Hope that help.

Hi guys,

I have the following config for NAT translations using the 7204 to terminate a small number of PPPOE sessions and expecting it to double over next month or so..  Most just get a public IP and don't do NAT but some I allocate an address to go through NAT.

interface GigabitEthernet0/2
description Interface for Internet Access
ip address x.x.x.x 255.255.255.240
ip nat outside
ip virtual-reassembly in
duplex auto
speed auto
media-type rj45
negotiation auto
!

ip nat inside source list 100 interface GigabitEthernet0/2 overload

access-list 100 remark IP list allowed to NAT
access-list 100 permit ip 172.16.0.0 0.0.255.255 any

I want to be able to use a larger range of IPs for the inside global but my google fu and understanding is failing me..  say I wanted to allocate.. 192.168.0.1/29  how would I do that?

I also have an NPE-G2 in it, what would be a reasonable number of sessions for it to be able to terminate?

Thanks,
Nathan
