Cisco 1721 - Losing Nat connection
Hi, I have a /29 ip address block. I am configuring my cisco router to be able to do NAT, what happens is that when I do the following config:
no ip http server
ip nat pool nat 66.196.xxx.126 66.196.111.130 netmask 255.255.255.248
ip nat inside source list 1 pool nat overload
ip nat inside source static 192.168.10.4 66.196.xxx.127
ip nat inside source static 192.168.10.5 66.196.xxx.128
ip nat inside source static 192.168.10.6 66.196.xxx.129
ip nat inside source static 192.168.10.7 66.196.xxx.130
when I save this confg and do a show run, only one static address is configured the rest of the static configs are not there, why is this? What can I do to resolve this problem?
Thank you,
a

You don't need to use the pool if you're doing static mappings.

Craig, in that case how do I rewrite the following line
ip nat pool nat 66.196.xxx.126 66.196.111.130 netmask 255.255.255.248 ?
Thank you
ip nat pool nat 66.196.xxx.126 66.196.111.130 netmask 255.255.255.248 ?
Thank you
Could you please send the full config?

Craig, my config is exactly what you have stated. I just need all my network traffic to go out of .126 and I am going to NAT 4 of my routers in my LAN via addresses .127 to 130. Yes, .126 is my WAN interface.
When I run the command you mentioned,
#ip nat inside source list 1 interface 66.196.xxx.126 I get the following error:
% Invalid input detected at '^' marker.
Where the marker point to the word 'inside". What could be the problem?
Thanks for the help.
