IP Sec remote access vpn can't access outside network

Jayzone_pl — Tue, 12 Mar 2019 02:58:29 GMT

Hi guys,

I tried to simulate ASA with 3 interface (inside=Sec.L.100; outside=sec.L 0; internet; sec.L=0). I configured ipsec remote access vpn (ikev1). what i tried to achieved is for the internet client to access the outside network.

using the PC at the internet interface side, i connected via cisco vpn client. i established the connection but can't access the network on the outside interface..

hope you can help me on this. thanks in advance.

IP Sec remote access vpn can't access outside network

Marius Gunnerud — Mon, 04 Nov 2013 08:56:22 GMT

Are there two ASAs involved or is that a copy paste fault?

Are you trying to connect using HTTP, HTTPS...etc.?

Have you run a packet tracer (I am assuming your VPN clients are on the 192.168.10.x network)?

packet-tracer input internet tcp 192.168.10.1 12345 80 detail

My initial guess is that this is most likely a NAT or routing issue.

Marius Gunnerud — Mon, 04 Nov 2013 08:58:49 GMT

Also, just out of curiosity, why did you do a replace all on the 1s?

IP Sec remote access vpn can't access outside network

Jayzone_pl — Mon, 04 Nov 2013 10:39:48 GMT

Hi Mr. Marius,

thank you for your reply.

yes, vpn is at 192.168.10.x subnet. I created the vpn thru the wizard. and nat is automatically created..

nat (outside,internet) source static any any destination static NETWORK_OBJ_x92.x68.x0.0_28 NETWORK_OBJ_x92.x68.x0.0_28 no-proxy-arp route-lookup

actually, i first created ipsec vpn in a way for the internet client to access the inside network. and it works fine. then i removed the ipsec vpn config. then created another scenario where in the internet client can access the outside network. but the access from internet to outside failed.

oops. sorry for the copy/paste error. +

hope you can help me for the troubleshooting.

thank you.

Jay

Re: IP Sec remote access vpn can't access outside network

Marius Gunnerud — Mon, 04 Nov 2013 13:42:01 GMT

Did you run the packet tracer...what were the results?

Is this in a lab? if you add the command management-access oustide are you able to ping the ASA outside interface from the VPN client located through the internet interface?

Just rememeber to remove the management-access outisde command once you are done testing

Re: IP Sec remote access vpn can't access outside network

malshbou — Mon, 04 Nov 2013 16:19:48 GMT

Hi Jason,

I would start with the following:

- packet-tracer from the outside to the VPN pool ( as we cannot simulate packet from a VPN tunnel in packet-tracer)

packet-tracer input outside icmp 8 0 detail

packet-tracer input outside tcp 80 1028 detail

- show crypto ipsec sa, and check encaps/decaps. You have a tunnel-all policy, so you may need to make a spli-tunnel tunnelspecified policy so that you restric the intersting traffic (VPN-to-outside) and trace its encaps/decaps properly.

- captures at the outside interface for the VPN-to-outside flow:

cap capout interface outside match ip

i am wondering if the hosts at the outside subnet have a correct route that points to the ASA as a next-hop to reach the vpn pool ... ?

Hope this helps.

malshbou — Tue, 05 Nov 2013 07:16:01 GMT

Hi Jason,

I am not sure if you source and destination IPs in the packet-tracer are correct. Please don't use the VPN pool as source in the packet-tracer, this will normally result in ipsec-spoof error.

Please do a similar packet tracer FROM an IP in the outside interface that should be reachable thru the tunnel TO an a pool IP that belongs to the test VPN client (i guess it is 192.168.10.1)

Regards.

Marius Gunnerud — Tue, 05 Nov 2013 08:06:33 GMT

Regardless of the spoof drop, it seems to be allowed from the VPN client to the outside interface. It would also be good to do the trace in the reverse direction also as Mashal has mentioned.

The next thing to do would be to start a packet capture between the internet and outside interface. You wont see any traffic coming in on the internet interface as this will be encrypted. But as long as traffic that is leaving the outside interface is not being encrypted we will see the traffic leave and the reply enter the outside interface.

Here is a link that shows how to perform the packet capture incase you haven't done it before.

http://www.cisco.com/en/US/products/ps6120/products_tech_note09186a0080a9edd6.shtml

Re: IP Sec remote access vpn can't access outside network

Jayzone_pl — Tue, 05 Nov 2013 10:24:37 GMT

here's the packet capture as instructed.

ingress interface: internet

capture is empty.

egress int: outside

1: 10:09:44.736946 192.168.10.1 > 192.168.145.100: icmp: echo request

2: 10:09:49.909758 192.168.10.1 > 192.168.145.100: icmp: echo request

3: 10:09:54.901106 192.168.10.1 > 192.168.145.100: icmp: echo request

as with the output it seems it has no reply.

i also tried the packet tracer from an ip located on the outside to the ip of the ip vpn pool (client). and here's the result.

Re: IP Sec remote access vpn can't access outside network

Marius Gunnerud — Tue, 05 Nov 2013 10:57:43 GMT

with the IP any any on the interface can the VPN user access the outside network?

are the VPN users on the internet supposed to be able to have full access to the outside network? In that case you could just add an ACL rule permitting the outside network to initiate traffic to the VPN users.

VPN users do not pass an ACL check so their connection is not entered into the state table and therefore return traffic is not permitted.

Re: IP Sec remote access vpn can't access outside network

malshbou — Tue, 05 Nov 2013 11:19:28 GMT

This is routing issue from the subnet (192.168.145.x) back to the VPN pool.

Please verify the routing at the internet subnet so that the return traffic comes to the outside interface of the ASA .

Regards.

hi guys,

it's on the routing issue. i successfully established connection after adding static route to router located on outside int.

thank you very much for your help.
