Hello Guys,

First of I would like to THANKS to even try to help me with this, so let me start my scenarios.


Building A (both building right next to each other)
1. I have a T1 internet connection with 30 static available IP range.
2. T1 is connected to my ASA5510 into eth0/0 (which is Outbound), on ASA5510 eth0/1 is my Inbound (where the LAN & VLANs are which consist of three Cisco 3560 switches) , ASA5510 eth0/2 is my DMZ (Exchange & DC also using 2 static IPs).
3. Cisco 3560 sw1 is physically connected to sw4 on Building B. (all have cisco 3560 & are on it's on vlan for management)

Building B (on different subnet)
1. Have DSL internet connected to a netgear router witch is connected to cisco 3560 sw4.


questions
I would like to get rid of Building B DSL internet and share the T1 from Building A. Is it possible for me to do this?

What I know is just run the internet wire from Building A sw1 to sw4 on Building B and it should give T1 internet access. HOWEVER that will be the same subnet as Building A which I don't want. I want Building B to be on its own subnet but share the T1 internet connection from Building A.

If i'm missing any information please let me know, but I do GREATLY appreciate any help.

So why not put building B in it's own subnet then? Not used an ASA myself, but with a Juniper SSG I can create a zone for each interface (and there are 9 of them)

I'd take a interface, put it in a new 'building B' zone with it's own subnet. If you need to use your existing switch infrastructure then just vlan them out

sound like you are not using NAT, and want to split the 30 public ip addresses between the
2 sites?

Looks like you just need VLAN's and a few config changes.
