This is a great forum, and I'm a total noob at this, but I have what probably is a really quick question....

I have two seperate network on both interfaces. One Public (204.x.x.x) and one private (192.168.99.x). How do get the two networks to communicate with each other? The router connects to the internet via 2 bonded T1s on a card.

If this is vague, let me know, and I'll post the config. Thanks so much!!!!!
 
Hello
Please post the "show run".Please be aware that directly connected subnets will talk to each other.So I guess your question isn't very clear.Please explain throroughly what you want to accomplish.Do you want the private addresses to talk to the Internet?
Regards
 
Ok, here's the long version on the what the config has to do..... on the 2811 there are two interfaces with attached networks- one public, one private. The private network will have to be able to see the internet, of course. Currently, i can ping out to the internet from the private network (f0/0), but I can't ping the public network addresses on f0/1 (although i can ping the public network interface, f0/1, from the private network).

I've tried to set up NAT on f0/0 and pinging to the internet from the private network is successful. I think through multiple configuration attempts, however, SDM has added some extra stuff (check out the access-list entries and interface overloads).

Also, as you'll see in the config, the static routes for the subnets on the private network have been defined. They all sit behind a layer 3 switch on the private network.

Here's the config...

I can also post a PDF of the network diagram, if that would help.

Thank you!!
 
Hello
The below statement is baffling me.Are you trying to say that you can't ping this subnet 204.228.x.x from the Internet?
"but I can't ping the public network addresses on f0/1 (although i can ping the public network interface, f0/1, from the private network)."

If this is the case try to ping this subnet 129.19.64.xx. from the Internet.If successful,then do a traceroute to the 204.228.x.x subnet.

Regards
 
Thanks for responding, Minue. To answer your question, no, I can ping the 204 network from the Internet. I can't ping the 204 network from the private network attached to the other interface, f0/0.
 
Take out acl 6 and 7, and make it

permit 192.168.0.0 0.0.255.255

I think you can only have one NAT statement, the second one taking effect. Then again, you can get out to the internet...

try it?
