Hi all,
I'm working towards my CCENT/CCNA and have a lab setup with 2 3750's and an 1841 router. For this question I'm only using one of the switches and the router. I'm also using a small netgear router so my roommate can continue to have internet access while I test things out. I have my 1841 router connected via f0/1 to my netgear router and from the netgear out to my isp. The 3750 is connected in f1/0/1 to f0/0 on the router. My IPs are included in the network diagram picture. The problem I'm running into is this: I can ping my ISPs interface and all the way to the internet(8.8.8.8) from my 1841, but I cannot ping even even to my ISPs interface(10.200.120.1) from the switch or any clients. Previously I wasn't even able to ping my netgear router's interface(192.168.1.1) with my switch, but I resolved that by creating a static route in the netgear to 10.0.0.0 /24 192.168.1.6. Here are my configs, any help would be greatly appreciated!
