VPN ACL & super networks
This should be a pretty simple question. With a tunnel can VPN you specify a wider range of IP addresses in the list to access such as 10.1.0.0/8 which accepts traffic from smaller subnets in this range like 10.1.3.0/24?
I don't know if the ACL check just the IP address, or if the subnet mask must be the same one.
For vpn traffic great nets will be read and processed, in other words if you set an address for correspondence as:
IP 10.0.0 allow 0.255.255.255 172.16.0.0 0.0.255.255
This will include the whole 8 subnets of 10 and 16 all of the subnets of the 172 to send on this tunnel.
Be careful when you use this part of the traffic you want to can be on this game.

With the help of Client VPN dial-up networking on L2l
I m tring to configure ASA 5505 with Cleint of VPN to access a remote network on a L2L with an another ASA 5505, but without success. There is a special function for this work?

Hello
You must ensure that you have configured following
- permit same-security-traffic intra-interface
- This will allow VPN Client traffic to enter the ASA and leave the same interface
- If you use Split Tunnel ACL with the VPN Client, make sure that the ACL has included Remote Site network
- If you use complete Tunnel this wont be a problem
- Make sure that the ACL of VPN L2L that defines "interesting traffic" includes the pool of Client VPN on both sides of the VPN L2L
- Configure a NAT0 on the ASA of Client VPN 'outside' interface that makes NAT0 for pool of Client VPN Remote Site network
If you have a real-world setting to share I can try to help with those. Otherwise I can only give general things like the above to check.

Cannot VPN in the network through PIX501
I have a pix 501 at home. When I try to VPN in our network via the VPN client I get authenticated but can't seem to our internal network. When I use my router netgear instead of the PIX I can VPN in and outside the internal network. Do I have to open some ports (if if ports) on the PIX or I have to change some configuration on the VPN client.
The problem is the PIX does not support IPSec, and PAT up 6.3 code coming out next year. Your VPN tunnel is based on UDP port 500 packets, which the PIX can PAT correctly. After that, all your packages are packages ESP, which is the IP 50 protocol which the PIX cannot PAT. If you have a second IP address from your ISP, you can create a static NAT translation in the PIX for your home PC and it works correctly.
Alternatively, if your VPN client supports IPSec encapsulation somehow in the TCP or UDP packets, then use it and it will work very well also.

Unable to connect to the internet and VPN in the network.
I have an ADSL account and when I vpn in our network using cisco VPN 3015 vpn client can't access the internet more locally. I have to use our internal proxy server on the network. Is it possible to make the vpn tunnel but also use the local internet DSL for browsing connection?
You must set up split tunnelling tunnel, while only some packets are sent through the tunnel, the rest get out in clear packages just as usual.
In 3015, create a list of network under Config - Mgmt policy - traffic Mgmt - list networks, this list includes your internal networks (you want to be dug traffic). Then go under the group to which the client connects to, on the Client configuration tab, select only the network of tunnels in the list, and then select your list from the drop-down list box. Reconnect and're you good to go.
Keep in the spirit of split-mining is considered a bit of a security risk because your PC is now accessible from the Internet AND you have a VPN directly in your internal network. If someone can take possession of your PC, then they have access to everything. You can also watch in allowing both client firewall stuff.

Adding networks to the tunnel VPN ACL
Hello. On a remote location, I have to add additional networks access to our networks to the central location and I was wondering is it as simple as the addition of these networks to ACL on both sides of the tunnel to allow access or is there something more to do? I just want to be sure because it is so simple.
VPN is the site to site.
Thanks in advance for any help.

Connectivity to the remote VPN site adjacent networks
Star topology with Corporate office which acts as hub (192.168.1.x) and remote sites connected by relay frames, except for another network (172.16.x.x) in the building served by 3560 switch company.
On my remote site vpn (10.0.1.x) I can ping network 172.16.x.x, but not the 192.168.1.x network. What I'm trying to do is to allow the network traffic remote 10.0.1.x (which connects directly via the VPN network 172.16.x.x) to reach the network 192.168.1.x and vice versa.
I'm sure its a combination of NAT/routing issue I forget.
I'm new to PIX / ASA in general and it's the first vpn L2L I install. If someone can point me in the right direction, I would appreciate it.
Thank you.
It looks like this?
10.0.1.x->-> Corp. ASA L2L tunnel - >->-> 192.168.1.x 3560 172.16.x.x
and that you can currently communicate via the tunnel between 10.0 and 172.16? In order to communicate between 10.0 and 192.168.1, you will need to define this interesting traffic and add it to your crypto and nat exemption acl.
Corp site

Hello
I have asa 5512-x
ASA 9.1 version 2
ASDM version 7.2 (1)
I'm not really good with a syntax of cisco, so I use asdm
I created a split tunnel remote ipsec vpn with cisco vpn client
the purpose is to allow vpn for LAN traffic
and to allow the vpn to a public Web site traffic
so I set the two objects and added to the exemption of split tunnel (the names of the objects: 'LAN', 'Rackspace')
access to the local network is ok, access to a Web site does not work
I guess I have some missing nat/ACL,
can someone explain to me please in the most simple way to do this?
Thank you very much
Hello
What is subnet
network of the NETWORK_OBJ_172.18.0.0_26 object
255.255.255.192 subnet 172.18.0.0This 'nat' configuration seems strange
NAT (LAN, WAN1) source static Tunnel VPN VPN Tunnel static destination NETWORK_OBJ_172.18.0.0_26 NETWORK_OBJ_172.18.0.0_26 non-proxy-arp-search to itinerary
When you see that the source for the "nat" interface is 'LAN' and source networks are those configured under "Tunnel VPN" it seems to suggest that this NAT configuration transmits traffic destined to 'LAN' and 'rackspace' to the 'LAN' interface. It is naturally very good for the subnet configured under 'LAN' , but the 'rackspace' to my knowledge is located behind an external interface of the ASA correct? But I guess I really need to know this as the subnet that I mentioned at the beginning of the post (which is used in this configuration NAT too)
What is the interface to which the VPN users connect to? WAN1 or DSL? Although the following list what the map interface Crypto is attached
See the crypto run map
You can also list the output of the following command

In the VPN 3000 concentrators network access problem
Hello
I created a group user ID, allowing simultaneously 3 session of this particular ID, when I am session VPN initating this particular ID, I can connect to a single session with any problem, and I can access the internal network. simulatneously trying another session from another machine using the same user ID, I get the ip address of the VPN server's internal network, but I can't ping internal LAN server and perform operations .only I get the IP address. But I'm nt problem in first session created, they problem arrive for the second session
Are the next two sessions of the clients that are behind a NAT/firewall device? Try to create a second group ID and log in to the second client and the second. If you still have the problem is not a problem of "simultaneous session."
If you see the problem either, and your customers are both behind the same NAT device, have your clients connect from different locations or enable NAT traversal.

Several tunnels to Datacenter VPN with overlapping networks
Hello guys,.
We are starting to host applications for customers who need trusts (maybe?) Windows and full access to a class C subnet in our IP data center.
My problem is most of our customers are small MOM and pop stores IPed to 192.168.1.x. I intend to install my own Cisco ASA in each of these sites and create a VPN to the data center to access the application. The last 2 sites I've done, I have re-IPed network to a mine plan. I start to run in many customers that we simply host the app for and I can't really make them Re - IP network if they do not want.
My question is what are my options here? I guess some kind of NAT, but I don't really know how it works. With a Windows trust communication must be 2 tracks. If we did not trust, I could see this work without problem with a simple NAT right? Firewall guy would you NAT on? The remote end or Data Center?
Any help and advice is appreciated.
I'm a complete network of Cisco, ASAs, catalysts, routers, etc...
Hi Billy,
Basically, for the overlap of networks, you will run natting on both sites for interesting traffic.
If you have networks that overlap, you can follow this link if you use Cisco ASA and this link for Cisco routers as a VPN endpoint devices.Kind regards

2 VPN to separate networks with the same intellectual property regime
We have an office in Bermuda and 2 offices in Chicago. 2 offices in Chicago have the same pattern of IP - 10.150.1.0/24. I would like to set up a VPN site-to site of Bermuda for each of the offices of Chicago. I have one up and it works fine. When I set up the 2nd, I can pass in Chicago, but not receive. I guess it has to do with the same IP networks. Is there a way around this problem?
Thank you
Scott
Yes you need to nat all traffic goes to one of the sights of Chicago. This way others will see it as a completely different subnet. It is a guide of cisco.com:

Hello
There is an "acl" parameter that is not clear to me, it is configured at customer site:
Crypto ipsec VPN ezvpn client
connect auto
Cisco key band EASYVPN
client mode
peer 10.0.0.1
username cisco password cisco
xauth userid local mode
ACL 101
Everything that I added to the ACL 101 tunnel is always present. I found a description:
Step 6
ACL {name - acl |} ACL-number}
Example:Device (ezvpn-crypto-config) # acl acl-list1
Specifies several subnets in a VPN tunnel.
"Specifies several subnets in a VPN tunnel". -what it means, source?
I tried to use this setting, and I added the access list:
access-list 123 allow ip 10.10.10.0 0.0.0.255 host 20.0.0.20
access-list 123 allow ip 50.50.50.0 0.0.0.255 host 20.0.0.20
where 10.10.10.0 and 50.50.50.0 are source and 20.0.0.20 is the destination.
When I ping with source 10.10.10.3 (physical int) for 20.0.0.20 - numbers of BA & desc packages grows.
but when I ping with source 50.50.50.50 (int loop) for 20.0.0.20 - I see that it wasn't to push into the tunnel.
Could someone explain how the work parameter and for what is it?
Thank you
Hubert
Hubert,
Ref:
in client mode several subnets are not supported, nor what they sense.
You specify what internal subnets of announcement to the server that are configured behind this device.
In client mode, the server sees only the assigned IP address.

How would I go about filtering out access to a port of a Cisco ASA vpn<>
By default, it seems that the VPN does not use the ACL on the external interface.
Thank you
As much as I know, that you can not. If you want to restrict to a certain group of users, you will need to apply the filter on the router upstream if you manage it. If the ISP handles this router for you, they may be able to do something for you.

LAN-to-LAN IPsec VPN with overlapping networks problem
I am trying to connect to two networks operlapping via IPsec. I already have google and read
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml
Details:
Site_A use ASA 5510 with software version 8.0 (4) 32. Site_A use 10.100.0.0/24, 10.100.1.0/24 and 10.100.2.0/24 inside networks. 10.100.0.0/24 is directly connected to ASA (like vlan10), 10.100.1.0/24 and 10.100.2.0/24 are routed.
Site_B use Linux box and networks 10.100.1.0/24, 10.100.2.0/24, 10.100.3.0/24 and so on (mainly 10.100.x.0/24). I have not implemented this ASA, we took over this infrastructure without other documentation whatsoever.
According to the above link I should use double NAT. Site_B will see the Site_A as 10.26.0.0/22 networks, and Site_A see networks in Site_B as 10.25.0.0/24. Site_A is allowed access only 10.100.1.0/24 in the Site_B, and Site_B is allowed access to all the networks of the Site_A 10.100.x.0/24 - so / 22 10.26.0.0/22 mask. I would like, for example, ssh to host in the Site_B to host the Site_A using 10.26.1.222 as the destination ip address (and it should be translated in 10.100.1.222 on the side Site_A). I'm looking for something like ip nat type match-host in Cisco routers - I want to translate only a part of the network address leave the intact host Party. Anyway, following the steps from the link displayed above everything is ok until the command:
static (companyname, outside) 10.26.0.0 access list fake_nat_outbound
which translates into:

Those are redirects to port on Site_A used for mail, webmail, etc. What should I do to keep the redirects from the Internet to companyname vlan and at the same time to have work l2l ipsec tunnel linking networks that overlap?
Thank you in advance for any help or advice.

Are you sure that static-config does not make to the running configuration?
By applying this 'static big' you're essentially trying to redirect the ports, which have already been transmitted by the rules in your existing configuration. This explains the caveat: what you are trying to do has some overlap with existing static.
(Sorry for the use of the transmission of the word, but this behavior makes more sense if you look at it like this; although "port forwarding" is not Cisco-terminology.)
But... whenever I stumbled upon this question, the warning was exactly that: a WARNING, not an ERROR. And everything works as I want it to work: the specific static in my current config simply have priority over static grand.
If you would like to try to do the other opposite you would get an error (first static major, then try to apply more specific) and the config is not applied.
So could you tell me the config is really not accepted?

When you ask the ORA-24247 utl_http package: access denied by access control (ACL) of network list
Dear all,
Need your help please.
Do in the face of ora 24247 network denial of access (ACL) even after following the procedure below. It was working fine until today where I did just drop and recreate again.
BANNER
Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
AMT for 64-bit Windows: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
Steps to follow:
Created an ACL with a user database and awarded connect, solve privilege.
Start
(DBMS_NETWORK_ACL_ADMIN). CREATE_ACL
ACL = > "utl_http.xml"
Description = > "HTTP access.
main = > 'TPAUSER ',.
IS_GRANT = > TRUE,
privilege = > 'connection ',.
start_date = > null,
End_date = > null);
(DBMS_NETWORK_ACL_ADMIN). ADD_PRIVILEGE
ACL = > "utl_http.xml"
main = > 'TPAUSER ',.
IS_GRANT = > TRUE,
privilege = > 'connection ',.
start_date = > null,
End_date = > null);
(DBMS_NETWORK_ACL_ADMIN). ADD_PRIVILEGE
ACL = > "utl_http.xml"
main = > 'TPAUSER ',.
IS_GRANT = > TRUE,
privilege = > 'address');
(DBMS_NETWORK_ACL_ADMIN). ASSIGN_ACL
ACL = > "utl_http.xml"
Home = > ' *',
lower_port = > 80,
upper_port = > 80);
commit;
end;
Confirmed the ACL configuration.
Select * from dba_network_acls;
HOST LOWER_PORT UPPER_PORT ACL ACLID
Select the hosts, lower_port, upper_port, acl in dba_network_acls where ACL='/sys/acls/utl_http.xml';HOST LOWER_PORT UPPER_PORT ACL
* 80 80 /sys/acls/utl_http.xml
SELECT the ACL, PRINCIPAL, PRIVILEGE, IS_GRANT FROM dba_network_acl_privileges where main = "TPAUSER."ACL MAIN PRIVILEGE IS_GRANT /sys/ACLs/utl_http.XML TPAUSER connect true /sys/ACLs/utl_http.XML TPAUSER solve the true -grant execute on utp_http to TPAUSER;
The performance of the procedure I have encountered the error message below. Don't know what step i missed here.
ORA-29261: bad argument
ORA-06512: at "SYS." UTL_HTTP", line 1525
ORA-06512: at "TPAUSER. SEND_SMS_NEW', line 70
ORA-24247: network access denied by access control list (ACL)
ORA-06512: at line 18 level
Your valuable support and help to get this issue resolved will be highly appreciated.
Kind regards
Syed
Thank you for all.
Problem solved in giving a superior port 8080.
(DBMS_NETWORK_ACL_ADMIN). ASSIGN_ACL
ACL-online "utl_http.xml."
the host => ' *'.
