Hey guys, long time listener, first time caller.
I've been looking at this for too long and I think I want to take a step back and ask you guys for some help. I have an 1841 behind my ISP's (Verizon FIOS) router. I have a single client connected to f0/1 of the 1841, and f0/0 is connected to an ethernet port on my FIOS router. Goes like this;
[ISP Router]->[1841]->[Client]
The network between the ISP Router and the 1841 is a /24 the also includes my "home" network. The default gateway for this network is 192.168.1.1 and is where my default route for the 1841 is pointed. I'm not positive the FIOS router is configured correctly, but if I can reliably pass traffic through the 1841, I'll move onto it. Additionally, the NAT to the public network (ISP's network/Internet) is thus handled by the ISP's router and not necessary in my configuration as far as I can tell.
The problem that I'm having is I cannot seem to get the 1841 to pass traffic from f0/1 to f0/0. NOTHING that I can find in the configuration points me towards an issue.

Yes, I know I'm running an old IOS version, however I don't have the capability to upgrade at the time (I'll get there as soon as I fix this issue).
From a client on the "home" network (with the ISP router configured as a gateway [192.168.1.1]) I can ping f0/0, but not f0/1.
From a client on the "home" network (with the 1841 configured as a gateway [192.168.1.254]) I can ping f0/0, but not f0/1.
From a client attached to f0/1, I can ping to the ISP router (192.168.1.1), but cannot ping anything on the internet {8.8.8.8).
Is there anything obvious that I'm missing?
Thanks in advance,
Tom
