Hi, I was wondering if anyone has manged to configure a cisco 887va router with layer 2 ports for CCNA project where I'm trying to get a internet connection from my home router. My home router is 4G router which does support bridge mode and the IOS version I'm using is 15.4. I've configured Vlan interface to take the layer 3 info and while my 887va router can ping 8.8.8.8 successfully, my pc can ping both interface of the cisco router but it can't ping my 4G router. I'd appreciate any help given.
My config file is below

Hello,
I don't understand your topology to be honest. What is the inside network, and what the outside ? 192.168.8.0/24 is Vlan 25 ?

Hi Georg,
My topology is ISP router / outside is 192.168.8.0/24 and the pc or switch is inside 192.168.10.0/24. I'll try your suggestion and let you know what happens, thanks.
