Any suggestions of what to try to fix the outside for this 831? Here's the setup. It's connecting to another internal router which runs through the building's infrastructure to a faceplate in a computer lab. Testing the inside setup with Ubuntu desktop, I was able to get assigned to the 10.0.0.0 network. However, ping has no route to the internet.
What's stopping this from getting outside?
Here's the current running-config:

Solved! Go to Solution.
I changed #2 to no effect. Here's the output for #1,
#sh ip ro Default gateway is not set Host Gateway Last Use Total Uses Interface ICMP redirect cache is empty
Looking how to solve this...
Here's another example config from a tutorial site for an 806 behind another router.  This is similar to my configuration.
Does it matter that my internal ip is 10.0.0.0 and the external ip from the current network is 10.0.0.0 as well? Should I change this to 192.168.0.0 or 10.10.10.0? Is this a possible conflict?
Fact is the router is getting DHCP from the external network and my internal NAT is assigning IPs, but they're just not connecting.
From the 806 example, there is this line:
ip route 0.0.0.0 0.0.0.0 22.214.171.124 !--- IP address 126.96.36.199 is the next hop IP address, also called !--- the default gateway. Your Internet service provider (ISP) can tell you what IP address to !--- configure as the next hop address.
I've replaced with this, simply because the external, which I receive at Ethernet1 is dhcp, and I don't know what it's going to be.
ip route 0.0.0.0 0.0.0.0 Ethernet1
What am I missing here?
Apologies for this, I missed your post a while back.
Can you post your full configuration at the moment together with a "sh ip route".
What exactly do you mean by packet loss ie. what symptoms are you seeing ?
No worries. It's a free country. haha.
Here's my current running config

And here's one more thing showing the ip assigned to the router, which shows up at restart:
Translating "eneiiiiee"...domain server (10.0.20.10) (10.0.1.16) % Unknown command or computer name, or unable to find computer address
I don't think I can describe it any better without more information. It appears to me the router gets an ip from the external network (LAN) and my computer connected to the router gets an ip from the internal network. But I still get no route to Host with a ping.
Here's a post from supportforums.cisco.com  describing a default route through dhcp with dhcp as the last argument of `ip route`
drizzledrazzle#conf t Enter configuration commands, one per line. End with CNTL/Z. drizzledrazzle(config)#ip route 0.0.0.0 0.0.0.0 dhcp ^ % Invalid input detected at '^' marker.
Is your outside interface up/up because if it was your routing table should show the static route you have in the configuration but it isn't.
What does a "sh ip int brief" show ?
This is frustrating. I can find detailed instructions for something like the 806 router , but this doesn't workout on the 831 router. Previously, when I've asked for assistance on this unit (before I bought an 871W and gave up for my personal use) one thing was people were giving me commands which didn't apply to this unit--no wonder I got it for $15 on ebay ! But this darn thing worked once.
drizzledrazzle#show ip int brief Interface IP-Address OK? Method Status Protocol Ethernet0 10.10.10.1 YES NVRAM up up Ethernet1 10.0.20.105 YES DHCP up up
I'm still really interested in solving this problem. Anyone able to help?
