Setting up WAN Access in Cisco 891F

[ofer1]

Hi Everyone,

I have a Cisco 891F router that I got second-hand for a lab environment that I am trying to setup.

I managed to reset it, gain access to the router, and set some things up, but I am unable to get access to the internet from a computer connected to the router.

I have set up my WAN interface as gigabit ethernet 8 and my default route is set up to point at the router provided by my ISP. If I log into the console of the router and try to ping an internet address, then it works with no problems. Same if I try to ping my ISP router (172.24.0.1).

The problem I have is that I cannot get this to work from a computer connected to the router to VLAN 1. I can connect from the computer to the router, and I can also ping the router's address on the WAN interface, but that is it. I cannot ping the IP address of my ISP router or anything on the internet. I tried setting up different access rules, but still couldn't get it to work.

I have attached the configuration file that I am using currently (without the passwords/secrets).

I know that there is something I am missing here, I just can't find what it is...

Hello
If you have internet connectivity from the rtr but not from vlan1 then append the following and test again:

conf t
access-list 10 permit 192.168.0.0 0.0.0.255
ip nat inside source list 10 interface GigabitEthernet8

That looks like it solved my problem, thanks!
