Brance Office can't browse the internet

[jepoyako]

I just linked two sites using cisco 2800 router and the link is now fine except the brance office can't browse the internet. Before, i link the two sites the main office got an ADSL and have their own dhcp/dns server windows 2003. The brance office use this dhcp server ( using IP helper in cisco). So basically, all the users in the main site can browse the internet coz their gateway is pointed to the ADSL where the brance office can't although the DNS from main site is use for the brance office. by the way I am using static route between the two cisco router. Please advice. Thanks

Post the configs.
Do ping tests.
Do tracert (traceoute on cisco) test
What can the branch office do?

The branch office use an IP Phones where the PABX is located in the main site. VOIP is working between sites just the internet.

Heres the config:

-------------Branch Office--------------------

interface GigabitEthernet0/0
ip address 10.3.0.1 255.255.255.0
ip helper-address 10.2.0.1
duplex auto
speed auto
!
interface GigabitEthernet0/1
no ip address
shutdown
duplex auto
speed auto
!
interface Serial0/1/0
ip address 200.1.1.1 255.255.255.0
no fair-queue
!
ip route 10.2.0.0 255.255.255.0 200.1.1.2
!
ip http server

----------------Main Site-------------------

interface GigabitEthernet0/1
ip address 10.2.0.253 255.255.255.0
duplex auto
speed auto
!
interface Serial0/1/0
ip address 200.1.1.2 255.255.255.0

ip route 10.3.0.0 255.255.255.0 200.1.1.1
!
ip http server

add default routes to each site

branch
ip route 0.0.0.0 0.0.0.0 s0/1/0

main
ip route 0.0.0.0 0.0.0.0 10.3.0.x

the x is your your internet gateway

Also, check you internet gateway, it may need a route to your branch site. If it is a cisco router, here is the command.

ip route 10.3.0.0 255.255.255.0 10.2.0.253

 

[jepoyako]

No, its not a cisco. Its normal ADSL router e.g netgear, dlink. Do i need to create an ip route from the adsl router?

 

[jdeisenm]

Yes, tell your adsl router about the network at the branch office.

Hi jdeisenm,


is the Ip route correct in the main site? you said 10.3.0.x or 10.2.0.x rather?

"
branch
ip route 0.0.0.0 0.0.0.0 s0/1/0

main
ip route 0.0.0.0 0.0.0.0 10.3.0.x

the x is your your internet gateway"
