I'm currently undergoing CCNa academy so I got a "job" from my boss to configure Cisco 871 router. Unfortunately we just finished first semester at academy so there are some things that I'm still having hard time to understand.
I managed to configure router so it connect to internet or to be exact it has internet access through another adsl modem that is in bridge mode.
Here is picture of setup
The problem is that users are not able to use internet when connected to this router. I'm able to access router through telnet ( ip 192.168.13.10) but that's it.
Here is the config from router http://pastebin.com/8JaMmqdT
192.168.13.0 255.255.255.128 is network that we use at work. 192.168.13.5 is IP address that is assigned to zyxel adsl modem ( If I'm correct, we could have used any address here since we are connecting this directly to router ? )
Zyxel adsl modem is connected to FA4 port on Cisco router. LAN cable is connected to FA0 port and from there it goes to switch ( it's some asus switch with 50 ports).
Here is routing table
Router-Cisco#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 192.168.13.5 to network 0.0.0.0 192.168.13.0/24 is variably subnetted, 2 subnets, 2 masks S 192.168.13.5/32 is directly connected, Dialer1 C 192.168.13.0/25 is directly connected, Vlan1 172.29.0.0/32 is subnetted, 1 subnets C 172.29.252.89 is directly connected, Dialer1 188.8.131.52/32 is subnetted, 1 subnets C 184.108.40.206 is directly connected, Dialer1 10.0.0.0/24 is subnetted, 1 subnets C 10.10.10.0 is directly connected, Loopback0 S* 0.0.0.0/0 [1/0] via 192.168.13.5
And here is IP interface brief

If I ping google dns from router e.g. ping 18.104.22.168 it works. If I ping www.google.com it doesn't work.
Also I'm able to access router via 192.168.13.10 but if I use router as default gateway then I'm not able to access the internet.
Can anyone point me in right direction here or tell me what I missed out ?
p.s. From where is network 172.29.0.0/32 is subnetted, 1 subnets C 172.29.252.89 is directly connected, Dialer1 comming from ? I cleared router config before starting and I don't remember configuring this one or that we use something like this at work.
