I bought this router from a friend,
I got the Cisco Configuration Assistant and the Cisco Network Assistant along with the internal java based control application for it. I managed to set up everything I think properly. The Vlan has DHCP set up and it is giving out IP's The Outside WAN interface (Fastethernet4) is set to DHCP and is pulling an IP from my ISP (Cox).
The issue I am having is even though my PC is getting an IP I have no internet access. I made sure NAT was set up to forward unknows to the Fastethernet4 interface. I even turned off the Firewall to ensure it was not blocking me..
Can anyone tell me what I may be missing?
Thanks in advance!
03-14-2011 11:03 AM
Could you please paste the running config for your router ?
The nat should be simple as given below
interface FastEthernet4
ip address dhcp
ip nat ouside
interface Vlan1
ip address 192.168.100.1 255.255.255.0
ip nat inside
access-list 123 permit ip 192.168.100.0 0.0.0255 any
ip nat inside souce-list 123 interface Fastethernet4 overload

Try removing the ACL 101 from FastEthernet 4 , .The last statement in the ACL is "access-list 101 deny ip any any log" ,while it should be "
interface FastEthernet4
no ip access-group 101 in

Yes .Try putting this commands and let me know if this solves the issue or not

The funny thing is I also have a PIX515e and it just does not like to work as well.. I am begining to think cisco gear is more trouble than its worth
03-15-2011 07:29 AM
The config. looks OK ,but may be something wrong with your connection ? .
Where are you connecting this Fastethernet4 ? to firewall ? and if firewall is not working how the router behind firewall will work ?
So just try to fix the firewall and then after that think abt router
