Configuring a 3945E for Internet Access

RBM01991
Level 1
Level 1

Good evening team,

 

I am in the middle of configuring my Cisco ISR G2 3945e as my home router. I'm replacing my standard Frontier router with the Cisco router.

 

My problem is that now as I've configured everything, my main computer in my bedroom is the only one that has internet access, and the one thing I've noticed is that in its default configuration, it gets the default gateway just fine. However my other devices do not receive my default gateway, even after attempting to reset their connections. All of my other wired devices are connected via a Cisco 4948 Switch. I can post the running config of that if it helps.

 

Here is the running config of the Router. Please let me know if you see anything off.

Hello,

 

the default router configured in your DHCP pool looks odd:

 

ip dhcp pool internal
network 192.168.1.0 255.255.255.0
default-router 47.198.202.82
dns-server 8.8.8.8 8.8.4.4
netbios-name-server 192.168.1.1
lease infinite

 

Change that to:

 

ip dhcp pool internal
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
dns-server 8.8.8.8 8.8.4.4
netbios-name-server 192.168.1.1
lease infinite

Like to see your Switch configuration and what port it is connected to your router also will be helpful email.

 

what IP address your computer got and it was working, how different this device connection compare to not working one.

 

what is this IP address in your DHCP config? - default-router 47.198.202.82
