Cisco ASA 5510 config help needed

Posted on 2011-10-10
Medium Priority
Last Modified: 2012-05-12
Trying to connect my ASA 5510 to a new internet provider. The provider gave us a cisco router that we can connect the ASA into.

We get a /27 LAN. I tried to scrub the config file to things that are necessary.

When I use a laptop the config works find. When I input it into the ASA there's no internet access. I can ping the gateway, but nothing beyond.

Any help would be appreciated. Thank you.

At first glance, this is rather interesting:
global (outside) 1
nat (inside) 0 access-list no-nat-inside
nat (inside) 1 tcp 20000 14000  udp 20000
nat (inside) 1 tcp 20000 14000  udp 20000

Try changing that to:

global (outside) 1 interface
nat (inside) 0 access-list no-nat-inside
nat (inside) 1
nat (inside) 1

Then give a 'clear xlate' and see what happens.

Also, if you got a /27, why are you using a netmask of (/30)?
