Yes, I have searched, googled, sworn, googled more but have not quite found the answer I need, .. I have also posted this on a Cisco forum but, as I discovered at stackoverflow, the Stack* forums generally tend to give clear , easy to understand answers, ... so hi,. and here goes:
I know some cisco basics but it seems my knowledge of the Cisco DHCP pools is less than what I thought. Our company has several 3825 (1gb mem) routers which we deploy from time to time for small temporary networks when these are required by our customers Now I have to use one of these routers for a group of 500-600 people on WiFi for a two day event. I took one of my old configs and changed the DHCP pool from 10.10.0.1/24 to 10.10.0.1/22. A assumed that it would just be a matter of changing the pool size and the inverse mask to match. All seemed to work well until the second range (ie: 10.10.1.x or 2.x) was given out. Clients get an IP address but there is no traffic possible to the outside world. I have no idea why. I have posted my config in it's full with just the passwords removed, there are no public IP's in it so no prob there.
Some extra info: My connection is a router provided by the venue, giving me a 192.168.1.1 address on my 0/0 interface.
Although absent in the below config I have tried:
ip route 0.0.0.0 0.0.0.0 192.168.1.1
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0
Neither of these seem to make any difference,... does anyone have an idea whet I am missing or doing wrong?
Thanks for your time!
