hello all! With help from other network gurus, I was able to configure my 1841 router and 1142N AP, and they are running pretty well now. So, as for my next challenge, I decided to connect two 1841 routers together, and with Cisco book's help, I was able to ping each other. However, I can ping between two routers, but can't ping anything outside of network, I.e any internet sites. Two routers are connected with serial port, and Eigrp is the protocol I used to connect two routers, and the first router is directly connected to cable modem. Do I have to add first router's routing table? or NAT trans pool? thank you in advance.
Solved! Go to Solution.

thank you for your answer. I forgot to mention that two routers are connected via T-1serial port. Also, now I have question that why Serial ports don't get DHCP address? what did I do wrong? is that because I used RJ45 cable with it instead of serial cable? thank you again!

then, here is IP route on Router2
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
S* 0.0.0.0/0 is directly connected, Serial0/0/0
1.0.0.0/24 is subnetted, 1 subnets
D 1.1.1.0 [90/2306560] via 10.0.0.1, 01:32:39, Serial0/0/0
2.0.0.0/32 is subnetted, 1 subnets
C 2.2.2.2 is directly connected, Loopback2
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.0.0.0/30 is directly connected, Serial0/0/0
L 10.0.0.2/32 is directly connected, Serial0/0/0
ISP address is subnetted, 1 subnets
D ISP address via 10.0.0.1, 01:32:39, Serial0/0/0
C 192.168.0.0/16 is directly connected, FastEthernet0/0
D 192.168.0.0/24 [90/2181120] via 10.0.0.1, 01:32:39, Serial0/0/0
192.168.10.0/32 is subnetted, 1 subnets

I think I'm half way there, but still can't see anything on internet browser. any help will be appreciated greatly. thank you
