Hi all,
 

I have an ISA 2004 facing the Internet in my HO.
 
ISA IP s

Public IP : 202.65.X.X
Private IP: 192.168.1.13
 
I have a HP Procurve router behind the ISA which connects to the Remote Branch over a P2P LL.


HP Procurve IP Settings at the HO
 
Private IP on  eth 0/1:192.168.1.238 - Facing the HO LAN
 
Private IP on Ser 0/1: 10.10.10.1 -Facing the P2P Link
 
Default Gateway : 192.168.1.13
 
The HO LAN has good access to internet - with either the ISA or the HP router as the Gateway.  
At the Remote  Branch:-Cisco router IP s
 
Private IP on Fe 0/2: 192.168.10.65 - Facing the Remote LAN
 
Private IP on Ser 0/2: 10.10.10.2 - Facing the P2P Link
 
Only one IP route on the Cisco Router
 
ip route 0.0.0.0 0.0.0.0 192.168.10.65
 
Now both the LAN s are communicating excellently with each other.
 
But I'm not able to pump internet to the Remote Branch.
 
Pls can any one help?

You did not mention what Cisco device you were using but I think you have the default route configured on the wrong network interface on the Cisco device? You will need static routes configured to each perspective network on all of your layer 3 network devices. You must configure persistent static routes on ISA using the “Route add –p xxx.xxx.xxx.xxx mask xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx“  command and have define their perspective IP ranges on the ISA’s Internal network properties. After that has been completed, make sure you have properly configured your access rules to permit access.

My bad.
It should be reading
ip route 0.0.0.0 0.0.0.0 Serial 0/1/0

file:///C:/Documents%20and%20Settings/xyz/Desktop/HO-BR.bmp

Other than these I have given proper policies on the ISA.
