Unable to NAT properly with 850 router

I am new to using the 850 router and having some issues with NAT working while also setting up my SITE-to-site vpn.

I have used this config on my 831 routers with no issues but I am not able to communicate out from the inside at all. No traffic accross tunnels or to internet

Can anyone see what I am missing?

I have atteched my config.

Thank You!

Re: Unable to NAT properly with 850 router

Hello,

the config contains "no ip routing", which turns off routing of IP packets. Thus you can not forward IP packets towards the Internet. Also CEF is turned off and usually the router has a better performance with CEF enabled. So please configure:

Router#conf t

Router(config)#ip routing

Router(config)#ip cef

Router(config)#end

Router#copy running-config startup-config

The rest does look not too bad, so lets start from enabling routing and then work from there.

Hope this helps! Please rate all posts.
