2600 Routing/NAT/DHCP Problem

aducey01
Level 1
Level 1

I really need to get this working soon, need to test a site to site vpn for work.

I'm connecting this to a home broadband connection and it's just not working right.  It looks to be natting, jusdging from the debugging, but the internal subnets are not able to ping out to the internet. 

It's not a dns issue 'cause I can't ping the numeric ip's to google or yahoo either.

The routes are in the routing table.

I can ping www.yahoo from the router cli and ping the inside hosts. 

boot system flash:c2600-adventerprisek9-mz.124-25d.bin

ip dhcp pool internal-client
   network 10.22.22.0 255.255.255.0

you're on the right track.  It's a router with a switch module.  Once I enabled RIP on the 2600 and rebooted the little isp router, it came right up.  Apparently the little generic isp router is running rip and needed the same from my router to do dynamic nat. 

This was quite the nose bleed. 

Excellent,

Would you please rate if any of the assistance was useful.
