Here is what i wanna set up:

PoC design - simple.png


Are there any guides or anything on how to configure th router, switch and ASA's?

EasyVPN is no important yet, its just the interfaces and the 2 VLAN's.


The ASA 5505's on left both need to have one VLAN on it with address pool 172.16.0.0/24.

Any guides for this kind of stuff? particular the switch and router?

I have this problem too.

Thanks for the guides guys, they did help.

I managed to configure the ASA 5505's but im having trouble with the router...

The router is a Cisco 831 model,

To describe the current situation a bit:

ASA 1 is connected to the 831 router on port 1

ASA 1 outside ip = 10.1.0.1

the Switch 2960 is connected with switch port 1 to the 831 router on router port 2

ASA 2 is connected to the switch on port 2

ASA 2 outside ip = 10.1.0.2

ASA 2 inside ip range = 172.16.0.1/24

ASA 2 PC client has IP 172.16.0.2

ASA 3 is connected to the switch on port 3

ASA 3 outside ip = 10.1.0.3

ASA 3 inside ip range = 172.16.1.1/24

ASA 3 PC client has IP  172.16.1.2

*see placement in the picture in post 1, together it should make sense


How can I configure the 831 router to properly forward the traffic so i can ping ASA 1 from both PC clients?

Anyone know what commands to use?

Thanks in advance!

I think this might work.

In the router:

ip route 172.16.0.0 255.255.255.0 10.1.0.2

ip route 172.16.1.0 255.255.255.0 10.1.0.3

ip route 192.108.254.0 255.255.255.0 10.0.0.1

In the ASA1:

route outside 172.16.0.0 255.255.255.0 10.0.0.2 1

route outside 172.16.1.0 255.255.255.0 10.0.0.2 1

In the ASA2:

route outside 192.108.254.0 255.255.255.0 10.1.0.1 1

route outside 10.0.0.0 255.255.255.0 10.1.0.1 1

In the ASA3:

route outside 192.108.254.0 255.255.255.0 10.1.0.1 1

route outside 10.0.0.0 255.255.255.0 10.1.0.1 1

Hi,

what is the subnet between router and  switch ,Genrally what i would recommend a easy solution make a common subnet for router port connecting to switch and ASA2 and ASA3 conecting in switch and if you want ASA2 and ASA3 client wants to ping ASA1 then drop route in both the ASA2 and 3 towards router port which is connected towards the l2 switch.

and in Router drop reverse route towards clients subnet with respect to ASA 2 and ASA3 interface.

let say router interface ip 10.1.4.2/24  --- switch --- ASA2(10.1.4.3/24) and ASA3(10.1.4.4/24)

route to ASA1 subnet in ASA2 and ASA3 will route outside 10.3.1.0 255.255.255.0 10.1.1.4.2 and in router will be reverse route towards the client subnet say ip route 172.16.1.0 255.255.255.0 10.1.4.3 for ASA2 client and ip route 172.16.2.0 255.255.255.0 10.1.4.4 for ASA3.
