ASA 5510 Remote access via Cisco VPN Client trouble

Hi Experts
I am trying to setup so staff can connect to remotely using Cisco client version 5 to the office.
This did work but now i have tweaked my settings to try to have the ability to connect to another LAN which is connected to this ASA via a site to site VPN. I can now ping my remote office but have lost ability to ping the LAN behind the ASA 5510

here is my config please please advise it must be something to do with NAT i receive the following message on the ASA

3 May 05 2011 12:24:22 305005 192.168.160.201 No translation group found for icmp src outside:192.168.160.62 dst inside:192.168.160.201 (type 8, code 0)

The first thing I would do is to give the VPN dhcp pool another range. One that is not overlapping with the inside range.

flowit

ASKER

HI
how do i do that i can create another range but how then do the IP addresses communicate with the networks i am trying to contact

the network IP is 192.168.160.0 and 161.0 subnet 255.255.255.0

Could i just use a 192.168.1.0 to 192.168.1.15 for example

What config then do i need to be able to work NAT rules etc

Thanks

flowit

ASKER

where in my config is it allowing access to the remote site the 192.168.161.0 network when i am connecting to the asa which is at 192.168.160.0 but i cannot ping this network
Thanks

Ernie Beek

I think this should do it:

no object-group network NEWDHCPPOOL

object-group network NEWDHCPPOOL
network-object host 192.168.1.1
network-object host 192.168.1.2
network-object host 192.168.1.3
network-object host 192.168.1.4
network-object host 192.168.1.5
network-object host 192.168.1.6
network-object host 192.168.1.7
network-object host 192.168.1.8
network-object host 192.168.1.9
network-object host 192.168.1.10
network-object host 192.168.1.11
network-object host 192.168.1.12
network-object host 192.168.1.13
network-object host 192.168.1.14

no ip local pool DHCPPOOLforVPNUsers 192.168.160.61-192.168.160.75 mask 255.255.255.0
ip local pool DHCPPOOLforVPNUsers 192.168.1.1-192.168.1.15 mask 255.255.255.240

Replace this line:
access-list inside_nat0_outbound extended permit ip 192.168.160.0 255.255.255.0 192.168.160.64
with:
access-list inside_nat0_outbound extended permit ip 192.168.160.0 255.255.255.0 192.168.1.0 255.255.255.240

flowit

ASKER

ok done
Will i need a rule permitting VPN POOL to any ip as i previously had?
I do not have the option ticked to bypass acess lists for incoming SSL and IPSEC VPN sessions

Thanks

Ernie Beek

Well, the line: access-list outside_access_in extended permit ip object-group NEWDHCPPOOL any
should still be there, thus allowing that allready.

flowit

ASKER

Brilliant really close
I have access to the Local LAN 192.168.160.0 with the new range of IP addresses on 192.168.1.0
but i cannot access the other subnet 192.168.161.0 any ideas?

Thanks

could you give me the lines i need for the other ASA as what you mentioned below

"And of course on the other end traffic to 192.168.1.0 255.255.255.240 must be allowed though the tunnel and exempted from nat"

would we need a ACL for the traffic
and how do i exempt from NAT

Thanks for your help
Regards John

Ernie Beek

It would be easiest if you could post the other config as well. I should be able to walk you through then.

I think that adding:

access-list inside_nat0_outbound extended permit ip 192.168.161.0 255.255.255.0 192.168.1.0 255.255.255.240

access-list outside_1_cryptomap extended permit ip 192.168.161.0 255.255.255.0 192.168.1.0 255.255.255.240

Should do the trick.

Ernie Beek

And of course:

access-list outside_access_in extended permit ip 192.168.1.0 255.255.255.240 192.168.161.0 255.255.255.0

flowit

ASKER

still not working bummer
Thanks

Ernie Beek

Hmm,

Let's do some logging then and see if anything is blocked. Try to get both the asa's logs when you attempting to vpn through. Then see if that can help us.

flowit

ASKER

I should be able to ping across won't i do i need any allow icmp rules?

I have a global allow icmp to any any but do i need a cryptomap or is this covered in the other statement

Thanks

Ernie Beek

That should be covered by the ip allow.

Allthough apolicy-map global_policy
class inspection_default
inspect icmp

Might be worth a try.

flowit

ASKER

Which firewall should i put these commands on?
i can see traffic hit the cisco its connected to and looks ok but then nothing mentioned about traffic coming in on other asa

do i need to debug the remote asa?

It worked before i changed the IP's to 192.168.1.0 but then my problem was that i could not ping hosts on Lan behind 192.168.160.0

not sure what to do now

Thanks

Any more ideas about this?

Looking at the FSWE-ASA001, it seems I might have forgotten one line :-~

access-list outside_1_cryptomap extended permit ip 192.168.1.0 255.255.255.240 Helsingborg_LAN 255.255.255.0
