Hi all...
I have this simple setup question that I'm trying to understand.
Scenario
Site A:
----inside network----[fw router]-------[wan router]---T1--internet
Site B:
----inside network----[fw router]-------[wan router]---T1--internet
I'm trying to understand how IP addressing work in this setup, where I am looking to establish a VPN/IPSEC tunnel between the FW routers of Site A and B. Also, the FW router will be doing NAT for remote user vpn dialup.
When ordering internet connection from telco, do I ask for 2 public subnets for each site? (one for wan router to internet and other for network between fw-router and wan-router) That way the fw-router will always be reachable via internet so vpn can establish?
Any thoughts or insights would be gladly appreciated. Thanks.
