topic Hello Ajay in Network Security

Type: HOST-LIMIT Result: DROP ASA 5505

vasquezwilmer — Tue, 12 Mar 2019 09:16:02 GMT

Hello,

I am having some weird issue with my ASA 5505. I have Remote VPN Host (172.16.32.100) that is pinging OK to some hosts behind the ASA Firewall (inside interface, 172.16.1.0/24). The problem is that others host cannot be reachable from the VPN Client Host.

This is what I have:

inside (172.16.1.0 /24)- - - - > [Firewall ASA5505] - - - > outside (24.xxx.xxx.xxx) --------VPN Client (Range 172.16.32.100 - 172.16.32.105 )

When I ran packet tracert, I see that HOST LIMIT is the cause of DROP packet, but I treat all network from VPN Client to my Inside interface as a network /24. I had read several documents, not sure if is a problem with the IOS or some limitation. Please help

The issue seems to be related

Ajay Saini — Tue, 25 Apr 2017 18:51:00 GMT

The issue seems to be related to the fact that you have 10 user license on ASA. Once that limit reaches, the further connections would be denied:

Inside Hosts : 10 perpetual

What do you see in syslogs when the issue is happening. You should be able to see logs indicating license overusage.

If you do a clear conn and try to initiate traffic, it might work for a while.

Hello

vasquezwilmer — Tue, 25 Apr 2017 19:50:11 GMT

Hello

You are right, it is getting

Deny traffic for protocol 17 src inside:172.16.1.205/34956 dst outside:24.233.167.168/53, licensed host limit of 10 exceeded.

So, If I disable DHCP service, and use only 10 host on inside interface (static), should it work with my current configuration?

Regards

As long as you are within 10

Ajay Saini — Tue, 25 Apr 2017 20:45:36 GMT

As long as you are within 10 user limit, it should work. Only in to out connections are counted:

http://www.cisco.com/c/en/us/td/docs/security/asa/asa72/configuration/guide/conf_gd/specs.html#wp1150495

If you disable dhcp and use 10 inside hosts statically, it should work.

I did but still getting

vasquezwilmer — Wed, 26 Apr 2017 13:03:21 GMT

I did but still getting result. I disable DHCP service on Firewall, and only 5 host was on inside interface, but cannot no ping from my VPN CLIENT 172.16.32.100 to 172.16.1.1 (Default Gateway Inside Interface), 172.16.1.2 (Switch Catalyst)...

when you initiate that

Ajay Saini — Wed, 26 Apr 2017 13:07:08 GMT

when you initiate that traffic, do you still see same logs. Could you please paste the out of 'show local-host' and syslogs

Hello Ajay

vasquezwilmer — Wed, 26 Apr 2017 14:05:40 GMT

Hello Ajay

THe SYslog didnt show licence warning, so the output is

ASA5505# show local-host detail
Detected interface 'outside' as the Internet interface. Host limit applies to all other interfaces.
Current host count: 6, towards licensed host limit of: 10

Seems to be no issue with License since I stopped DHCP service.

I dont know why 172.16.1.1, 172.16.1.2, is not responding from my VPN Client.

Could you try to shift the

Ajay Saini — Thu, 27 Apr 2017 12:53:15 GMT

Could you try to shift the below NAT higher in order than the dynamic NAT.

Within Manual NAT section, the order matters.

Remove the NAt at line 2 and add the below :

nat (inside,outside) 1 source static INSIDE_NETWORK INSIDE_NETWORK destination static _RA_Host _RA_Host no-proxy-arp route-lookup

Let me know how it goes.

I did, now I have only four

vasquezwilmer — Sat, 29 Apr 2017 00:16:43 GMT

I did, now I have only four host behind the firewall. All host are pinging now, but I cannot reach default gateway (Firewall Interface inside) 172.16.1.1.

Remote access client 172.16

Ajay Saini — Mon, 01 May 2017 12:37:44 GMT

Remote access client 172.16.32.100 not having default gateway is fine. Since you have a split tunnel, not all the traffic originated from client will be sent to ASA. If you wish to access internet from remote client by connecting to the ASA, you would need to use tunnel-all option and send all the traffic through vpn tunnel.

To be able to ping inside interface from vpn client, you would need below command:

management-access inside

For the vpn client to be able to access internet, once you use tunnel-all, you would need nat policy on outside interface, something like:

object network _RA_Host
subnet 172.16.32.0 255.255.255.0

nat (outside,outside) dynamic interface

Also, you would need this command:

same-security-traffic permit intra-interface

Refer to this example link, it talks about pretty much same scenario:
