  • Thread-topic: Help for Tunnel configuration

Hi,
I've a problem with Tunnel configuration. I've to connect two lans with
a tunnel:


LAN1----|FW-1|----|ISP ROUTER1|---------   INTERNET ------|ISP
ROUTER2|---LAN2



FW-1 makes NAT for LAN1.So I've got Private IP between LAN1 and FW-1 and
Public IP on the other side of FW-1.
The tunnel is created by the ISP between ROUTER1 and ROUTER2.
LAN2 must be connected to internet only through LAN1. (No direct
internet access via ROUTER2)



- Is it correct that between FW-1 and ROUTER1 coexist packets with
Public and Private IP ? Or this may lead to security problems ?

-What is the best solution for security ?

Thanks for the answers and I hope that my english is corrected :)


Bye

Flavio Berta
