Re: Re: IP Tunneling - Typical requirement

2001-02-02 Thread A Mateen


The customer is running the Checkpoint firewall which is registered with IP address of 
the other ISP ( the existing one). Now they are going to take a DS0 connection from 
our network. 
For them to change the IP or add IPs at firewall they require to minimun of 30 
days.Meanwhile, they want to use both the lease lines from us and from the other ISP.
The customers total network and Servers are behind the firewall. Hence they have the 
only exit pont from firewall which inturn pointing to the ethernet interface ( 
configured with the other ISPs) as the firewall Gateway. Now, if they take my link 
with another serial port then how do i serve their LAN (inside the checkpoint FW). 
They want to go in only with this firewall.Security between the links is not of 
concern.
- xyz ISP
LAN  FW --- Router
- my ISP

The FW/dns /web server r configured with the xyz network 
and they need min. 30 days to change the ips to my ISP.But they want to use the 
services to both meantime.
How do I accomplish this. What I thought is like this.
1. Ask the xyz to allow the adv of their part of the 
   network with us. ( This is ruled out as they are not  
   accepting)
2. Create a tunnel of IP over IP on the my ISP serail inface. Convert the other IPs 
request into my ISP IPs and route their request via my network, 
How can I do this with out using any additional SW ( ie only using cisco routers ).

UR reply is appreciated

If I understand your requirements correctly, what you
need to do is configure and IPSEC tunnel between your
network and the customer network. Many companies that
are doing business via the internet use IPSEC to
create secure encrypted access into their intranets or
extranets.  If you not concerned about security of
clear text traffic between your companie and your
partners then just simply open up your router/firewall
to permit this connection.
