ASA to allow internet traffic to multiple networks

jwood1650 — Tue, 12 Mar 2019 01:30:15 GMT

The attached jpeg shows my network. I want to be able to access the internet from all routers behind the ASA. How is that done?

Hi Jonathan,

What version your ASA software running?

"I want to be able to access the internet from all routers behind the ASA. How is that done?"

Hi Jonathan,

What you need is do on your ASA is dynamic-nat for your internal private addresses to be able access the internet.

object network obj_R2

host 10.0.12.2

nat (inside,outside) dynamic interface

now do that same for other routers for their outside interface.

Hope that helps.

Thanks

Rizwan Rafeek

Re:ASA to allow internet traffic to multiple networks

jwood1650 — Wed, 17 Apr 2013 17:09:38 GMT

Thanks so something like this:

object network
obj_R2 host 10.0.12.2
nat (inside,outside) dynamic interface

object network obj_R4
host 10.0.13.2
nat (inside,outside) dynamic interface

object network obj_R3
host 20.0.24.2
nat (inside,outside) dynamic interface

object network obj_R5
host 30.0.35.2
nat (inside,outside) dynamic interface

Do I need the same thing for R1 or something different since it is directly connected

"Do I need the same thing for R1 or something different since it is directly connected"

Hi Jonathan,

same will work.

So I applied the config you gave me, but I still can't seem to ping outsite.

Here is a test from my R4

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:

Re:ASA to allow internet traffic to multiple networks

Hi Jonathan,

When you ping from the router, you have to source the ping from the interface that permited for dynamic-nat.

such as this:

ping 4.2.2.2 source 10.0.12.2

thanks

Played around last night sbd got the ASA to ping all routers and all routers to ping the ASA. Only problem is thst I still can't access the internet from my client pc on the 30.0.36.0 network. I try to ping Google but it comes back as saying destination host unreachable.

"I still can't access the internet from my client pc on the 30.0.36.0 network."

You have to create a dynamic-nat on the ASA for that subnet as well and please make sure that you have a default route on the router (i.e. rouer which host the subnet:30.0.36.0) to push all internet bound traffic to next-hop address.

object network obj-30.0.36.0

thanks

Re:ASA to allow internet traffic to multiple networks

jwood1650 — Thu, 18 Apr 2013 15:28:45 GMT

what would the defaul route be?

ip route 30.0.36.0 255.255.255.0 10.0.10.1

Re:ASA to allow internet traffic to multiple networks

jwood1650 — Thu, 18 Apr 2013 15:56:19 GMT

Hi Jonathan,

See, if you can ping 4.2.2.2 from the ASA itself.

thanks

So from what I know (not too much...yet) my config should allow my PC connected to the 30.0.36.0/24 network have internet access. I can ping from the CLI on R5 to the ASA, and ASA to R5. I can also ping the ASA from the client PC and visversa. But I can't seem to get to the internet. Do I need a default route statement on all my routers to allow this? I'm stumbted at this point.

That is a normal behaviour as result from your icmp deny any outside command on the ASA, try to remove that line or allow only google ip just for testing purpose. below commands are to allow ping only from 8.8.8.8 to your outside interface and deny any other ip that tries to ping your outside interface.

icmp permit host 8.8.8.8 outside

icmp deny any outside

EDIT: make sure the icmp permit host 8.8.8.8 outside command is above the deny any command.

Thanks Rudy, that worked for the ping test....but I still don't have internet access on my client PC. Can't ping 8.8.8.8 form it, but can ping the ASA 10.0.10.1.

Does my config above look right for the Client PC (30.0.36.4) to access the internet?

Do I need another static route on my ASA for the 30.0.36.0 network?

Sorry just at a loss right now with this...

Thanks in advance for the help.

Figured it out...just needed to default routes on all my routers. Works just fine now. Thanks all for the help.
