Cross post from /r/homelab
Good Evening,
Im working on setting up a Cisco 2951 in my home lab with VLANs. As far as I can tell all the vlaning is correct and im able to ping the sub interfaces from all the vlans, im also able to ping other hosts in each vlan from each other (i can ping 172.16.20.1 from 172.16.10.100). Im working on creating that NAT translation now and im not able to ping out to the internet. From my laptop (172.16.10.100) i can ping 172.16.10.1 (the routers internal interface) and 192.168.1.2 (the routers external interface) but i cant ping 192.168.1.1 (the next router up before the internet). From the router console I can ping 192.168.1.1 and out to the internet (8.8.8.8). Im not sure what im doing wrong, ive attached the running config.
Any help is appreciated!
