VPN Client und Cisco asa 5505 tunnel work but no traffic

dsosin1975
Level 1
Level 1

Dear all,

I am a new in this forum and don´t have a lot experiance with Cisco , so that I hope that I can have help from the side of specialists.

I have following problem:

I installed und konfigured ASA 5505 for using with vpn client. I would like to give access from outside through vpn to the local network.

For testing I installed ASA 5505 with ADSL connection (pppoe) and tried to give access to internal network.

Of course everytime I recive different IP address from provider, but it is not a problem reconfigure it in the vpn client.

After connection is established (vpn tunnel is working) I can see packages from my outside network. But I don´t have any connection to internal network.

I cleared my configuration yesterday and tried reconfigure ASA again. I didn´t tested it again yesterday, because it was to late. And I know that I don´t have permission rule at the moment by ACL. But I think that I will have the same problem again.( tunnel but no traffic).

What I do wrong. Could anybody let me know what I have to do today.

With hope on your help Dimitri.

Configuration of ASA after reset and basic configuration: Internet from inside of course is working.

Hello, yes I have public IP address before tunnel is established and I have priva

te ip address from my pool after tunnel is established.

regards. Could you make maybe remote session through teamviewer for example? This is not company asa, so that I can give access

dimitri

Hello,

Can you run these packet tracer commands on the firewall and post the output

here:

packet-tracer input inside icmp 192.168.1.5 8 0 192.168.10.1 detailed

packet-tracer input outside icmp 192.168.10.1 8 0 192.168.1.5 detailed

Regards,

NT

i reseted my configuration. And setup everything again with the same result. By configuration i didn´t configure splitt tunel.

Below new config and trace.

best regards,

dimitri

Hello,

OK, the packet tracer says that the communication is allowed. Can you try to

ping 192.168.1.1 from the VPN client?

Regards,

NT

yes I can reach 192.168.1.1 (local interface of ASA) but not local IP of client.

O my got I am so stupid. I have f-secure as antivirus with firewall. I stopped the service during my last test, but after restart of PC it was of course enabled again. I configured exlusion rule and it worked!!!!!

Could you please check if other configuration is without any mistakes and secure. I don´t have a lot exprirence with asa, so it is still difficult.

Sorry for your time.  But I learned a lot from troubleshouting.

I have to configure only split of tunnel and also I need in the future change using authentification from local databse to windows radius. Do you know maybe example of configuration with asdm console? Do you have some tipps?

best regards,

dimitri

Hello,

Your configuration looks good. Yes, configuring split tunneling is a good

thing. Here is a sample configuration for windows authentication:

aaa-server test protocol nt

aaa-server test (management) host test.abc.com

nt-auth-domain-controller test

aaa-server test (management) host 192.168.1.2

nt-auth-domain-controller test

tunnel-group RMT general-attributes

address-pool RMTPool

authentication-server-group test LOCAL

default-group-policy RMT

This will allow all domain users access to the VPN.

Hope this helps.

Regards,

NT

thank you for your help I will read on weekend a bit of configuration of radius for windows and also for asa.

have a nice day.
