No Nat with 9.0(1)

[MarcoM]

Hi all,

i have a config with access Vpn Client with range 192.168.2.x.

When connect with client i cannot access on local lan 192.168.1.x.

I checked the nat and everything seems ok, what's wrong?

Thanks in advance.

Hi,

Your "object" are the wrong way in the NAT configuration

The LAN and VPN pool needs to be switched with each other

Hi JouniForss,

thank for reply.

From:

nat (inside,outside) source static PoolVPN PoolVPN destination static LAN LAN no-proxy-arp

To

nat (inside,outside) source static LAN LAN destination static PoolVPN PoolVPN no-proxy-arp

right?

[Jouni Forss]

Hi,

Yes, that is correct.

I tried this configuration, but still does not work.. :-(

[Jouni Forss]

Hi,

Just incase it causes problems, remove the VPN pool from the Split Tunnel ACL.

[MarcoM]

i removed

access-list VpnOut_splitTunnelAcl standard permit 192.168.2.0 255.255.255.0

but does not work from client vpn. (I also disconnected and connected)

[Jouni Forss]

Hi,

Starting to sound more of a problem with the actual VPN Client computer or the host on the LAN to which you are trying to connect to.

Has this worked at any point? Or is this a new connection completely?

Have you confirmed if any connections are visible on the ASA that you are attempting from the VPN Client?

Is the service you are trying to reach enabled on the host on the LAN?

If this is ICMP traffic then I would suggest adding the configuration that was on the ASA by default. Something like this

class-map inspection_default

match default-inspection-traffic

policy-map global_policy

class inspection_default

  inspect dns

  inspect sqlnet

  inspect sunrpc

  inspect tftp

  inspect icmp error

  inspect h323 h225

  inspect h323 ras

  inspect ip-options

  inspect rtsp

  inspect skinny

  inspect icmp

  inspect esmtp

service-policy global_policy global

And mainly in the above we are looking to enable the "inspect icmp"

Though in your case the VPN traffic should be allowed through the ASA by default so I am not sure if the inspect ICMP is required.

Also if its possible I would suggest using the "packet-tracer" command when you have the VPN Client connection active. What you should do is check the IP address you get from the ASA for your VPN Client then use it in the below command while also filling the information for the destination host and port

packet-tracer input outside tcp 192.168.2.x 12345 192.168.1.x

OR

packet-tracer input outside icmp 192.168.2.x 8 0 192.168.1.x

[MarcoM]

Thanks angain for reply Jouni.

I deleted and recreated the pool PoolVPN and it worked.

Now i have another issue with access to ASDM via vpn remote access.

I set this permission on config:

aaa authentication http console LOCAL

http server enable

http 192.168.1.0 255.255.255.0 inside

http 192.168.2.0 255.255.255.0 inside

but does not work. I also tried to set the outside interface (not inside on http) but without success.

How can I fix?

Thanks.

Hi,

Try adding

management-access inside

This should allow you to access the "inside" interface IP address for management purposes through the VPN connection. Otherwise it would only be possible to use the "outside" IP address for management through VPN Client if the "outside" IP address was forwarded to the VPN client connection also. (Either by using Full Tunnel or adding the IP address to the Split Tunnel perhaps)

Please do remember to mark the reply as the correct answer if it answered your question.

Ask more if needed

- Jouni

[Jouni Forss]

Ah,

You seemed to already have the "management-access" command.

This should allow management connections through VPN also using the "inside" IP address of the ASA.

- Jouni

[MarcoM]

Right Jouni already have in config command "management-access inside" but does not works, cannot manage ASDM of ASA.

[Jouni Forss]

Hi,

It would seem that you have to change the VPN Client to Full Tunnel for this to work

Here is a quote from the Cisco documentation regarding the command "management-access"

This command allows you to connect to an interface other than the one you entered the ASA from when
using a full tunnel IPSec VPN or SSL VPN client (AnyConnect 2.x client, SVC 1.x) or across a
site-to-site IPSec tunnel.

This could be achieved setting the "split-tunnel-policy tunnelall" in the "group-policy"

Hope this helps

I have this command in config:

group-policy VpnOut internal

group-policy VpnOut attributes

dns-server value 8.8.8.8

vpn-tunnel-protocol ikev1

split-tunnel-policy tunnelspecified

split-tunnel-network-list value VpnOut_splitTunnelAcl

access-list VpnOut_splitTunnelAcl standard permit 192.168.1.0 255.255.255.0

[MarcoM]

i set also full tunnel but does not works.
