Branch Internet Config Help 2

[jason985]

I am having problems getting my branches access the internet. How my network is setup is at the main branch I have a T1 out to the net and each branch has a PTP to my main branch. I need my remote branches to be able to access the internet from my main branch. I am not having any problems having my main site access th internet.

My current configuration at my main branch is Cisco Internet router - PIX – Cisco branch router – local network switch.


My main branch router looks like this
Current configuration:
!
version 12.0
service timestamps debug uptime
service timestamps log datetime
no service password-encryption
!
hostname
!
!
interface Ethernet0/0
ip address 192.168.1.253 255.255.255.0
no ip directed-broadcast
!
interface Serial0/0
description Branch1
ip address 192.168.0.5 255.255.255.252
no ip directed-broadcast
!
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.1.254 (this is my pix)
ip route 192.168.2.0 255.255.255.0 192.168.0.6
!
!
line con 0
password
login
transport input none
line aux 0
line vty 0 4
password
login
!
End

On the remote branch router the config looks like this

Current configuration:
!
version 11.3
!
hostname Branch1
!
enable secret
!
interface Ethernet0
ip address 192.168.2.0 255.255.255.0
no ip directed-broadcast
!
interface Serial0
ip address 192.168.0.6 255.255.255.252
!
!
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.0.5
!
line con 0
password
login
!
end

Do you have the Pix configured to NAT the 192.168.2.0 subnet?

 

[fdurham]

Jason- Can you post your pix configuration, i think thats where the problem is. Looks like the pic doesn't know where to send the traffic back to the branch site.

I dont know too much about the PIX. It was setup before I got here. I don't think it is configured to NAT 192.168.2.0 network. I am not sure though. Let me get a copy of the config for you.

TIA

JOAMON,

Its not the nat command because he has the nat (inside) 1 0.0.0.0 0.0.0.0 and the global (outside) 1 199.xxx.xxx.xxx netmask 255.255.255.255. What this is saying is everything from the inside interface assign it to the extern IP address of 199.xxx.xxx.xxx.

Jason-

What you are missing is this command; route inside 192.168.2.0 255.255.255.0 192.168.1.253. This command will aloow your branch user on the 192.168.2 network to use the internet through your main branch. For every other branch office you add, you add another route statement to your Pix.
