I have an iPAD. It connects to my ASA5520 via IPSEC. When it connects it gets an IP address from the ASA but it does not get any of the other stuff. Specifically the DNS suffix. How to correct it?

View 2 Replies View RelatedWe recently replaced our Cisco 5510 with a 5520. I had the SSL Client VPN working on the 5510, I cannot get it working on the 5520. The IOS version is 8.2(5) and the ASDM version is 6.4.I run through the SSL Client wizard and get everything set up. When I try to get to my outside interface Internet Explorer just comes up with an error. When I try to connect through the Cisco AnyConnect client on my Android it used to come up with a "No address available for SVC connection". After deleting an address pool not even related to my SSL VPN profile I cannot get that far. I just get a "login failed". Even after I create a user with level 15 privilege and assign to my vpn group policy.I still get the "No address available for SVC connection" when I try to connect to the default profile, which doesn't really go anywhere.

AAA.AAA.AAA.AAA is the ASA public ip in the outside
BBB.BBB.BBB.BBB is the jupiter device ip (part of the object group IP_LIST)
CCC.CCC.CCC.CCC is the nat ip on the ASA
10.21.0.164 is the real address in the inside(code)
I guess I'll start with the easy stuff, Cisco ASA 5520 ver 8.2, ASDM ver 6.2, IPSec L2L tunnel with overlapping private IPs.
I have about a dozen L2L connections on our 5520 but never had to do one with overlapping IPs. I have two that I have to build and one definitely overlaps our inside locals, and the other is requesting that we NAT our inside locals to a 10.x.x.x.
I've searched the board and found several good posts including document 112049, but I just don't seem to be able to get my head around how to translate one inside address to another. It would seem like is would be as easy as doing an (inside,inside) static NAT, but most everything has the solution as a policy NAT or doing an (inside, outside) but in the less secure address space place the name of an ACL. I have ordered that brick of a book on ASAs from Cisco Press, but need to get something going and I'm not having much luck getting this thing up and running.
Perhaps my basic understanding of NAT rules is wrong. I thought that when using NAT the command speaks to the interfaces and the direction of travel, (inside,outside). I also thought that the IP adresses used must be valid on the interface refferenced, so any refference to "inside" would have to be an address on the "inside interface of the FW and likewise for the "outside" interface. Finally, to be sure I'm not calling a duck a goose my understanding is that the following are correct; "inside local" = my private, "inside global= my peer, "outside local"= their private, "outside global"= their peer.
So if I'm translating say a 192.x.x.x on my inside local and wanted to present them a 10.x.x.x, wouldn't I need an (inside,outside)? And even though I'm translating my private IP into a different private IP, the translated IP must be on the "outside" interface because that is the interface that I want to present the new private IP on?
So for the scenario I suggested at the top where I need to translate my private 192.x.x.x into a 10.x.x.x and present that 10.x.x.x to the other side, I need something like NAT Static (inside,outside) 10.x.x.x 192.x.x.x?
I've been tasked with retiring a VPN Concentrator 3000 and replacing it with an ASA 5520. I'm trying to get a handle on how to set up the NATs and ACLs, since most of my experience is remote access VPNs, not site-to-site. Plus I've not configured a VPN 3000 in about 6 years so I'm having to re-learn a lot of the interface.
The VPN 3000 has a feature called LAN-to-LAN NAT rules that basically allow you to NAT an address on your internal network to an address on the "local" network for the LAN-to-LAN connection so it can then go through the tunnel to the remote side. The config looks something like this in the VPN 3000: [code]
Which looks to me like a "Static Policy NAT" in ASDM. So I set one of those up, that should be translating 172.16.3.151 on the inside interface to 192.168.200.151 on the inside interface (yes, the same interface) which should then (logically) be picked up as "interesting traffic" by the crypto-map and sent across the VPN tunnel. However, that doesn't seem to be the case - both the "packet trace" in the ASDM and traceroute from the source workstation show the packets getting to the inside interface, and then passed right out the outside interface to the internet router (which then drops the packets as they're a private IP).
what else do I need to do to make the crypto-map pick up the NATted traffic?
We are using Any connect vpn client (v2.5.3055) to an ASA 5520 (v8.4) in a development environment. We use our corporate Radius server to authenticate users. We have certain users which need have the same IP address every time they lo gin. As it is configured now, the IP addresses are assigned sequentially from the pool. Is there a way to allow certain users to get the same IP address each time they log on?
View 3 Replies View RelatedWe have a Cisco ASA 5520 and in order to conserve public IP addresses and configuration (possibly) can we use the same public IP address for a static NAT with two different interfaces? Here is an example of what I'm refering too where 10.10.10.10 would be the same public IP address.
-static (inside,Outside) 10.10.10.10 access-list inside_nat_static_1
-static (production,Outside) 10.10.10.10 access-list production_nat_static_1
I have setup an AnyConnect Connection Profile on my ASA 5520.
We have some remote support software which the helpdesk use to connect to PC's remotley and torubleshoot.
I cannot connect to this software using the assigned IP address of the client even though it works fine with our old Nortel VPN.
If I hit the IP address the packet gets all the way to the ASA and seems to disappear.
I have setup an IP v4 access list on the connection profile which allows any/any access b ut still no joy.

2- Any sample config for ASA 5520 for this type of network?
Got an ASA5520 running V8.2(3) and we want to upgrade our internet bandwidth. Our ISP says OK but we need to install different physical circuit, upgrade CPE router, etc.
Then they say, btw your globally allocated IPs will change - this is a problem as we have Site-to-Site VPN Tunnels, IPSEC RA, etc.
ISP are proposing to give us a 3 month period whereby old & new IP blocks will be routed to our ASA (by means of secondary IP address on their Cisco CPE).
Multiple IPs on the same physical i/f on the ASA require sub-interfaces/IP Addresses/VLAN ids on my "outside" i/f.
Is this going to horiibly break Site-to-Site VPN Tunnesl, IPSEC remote access ?
Will VLANs work at all with IPSEC on the "oustide" i/f at all ?

View 1 Replies View RelatedI am desperate to make some kind of translation which convert an outside IP Address of our web server to its inside ip address so that requests can be routed internally to the server.
This is what we have: A wireless network with an SSID to serve visitors. We also have an in-house web server which can be accessed internally and externally. We have a ASA 5520 that protects the internal network, including the Web server, and also routes all traffic from the all visitors connected to the public SSID to the outside. The DHCP server for the wireless network for visitors is configured to give the 8.8.8.8 as dns server. The problem with that is that the www.ourwebserver.com is resolved by Google's dns server to the public IP Address of our web server! The traffic then is sent to the outside interface of the ASA 5520. The visitor who wants to access our web server cannot connect!
How can I configure the ASA to route that traffic to our web server with the public ip address to the inside ip address of the web server?
Switch is a Nortel 5520
PC is Windows 7, with Intel 82579LM adapter
When PC was first attached to network, it could not ping gateway(switch). Turns out it was broadcasting for the gateway's MAC address, but never got a response. Tonnes of testing later, if I just change one number on the MAC address of the adapter, it receives a reply from the switch and can ping the gateway.
Why doesn't the native MAC address work?
Update: Just the vendor portion is the determining factor. As long as it starts with 2C-59-E5, it will not work. 2C-58-E5 will.
Update 2: Pinging anything in the same subnet works, just pinging the gateway interface of the switch doesn't happen. Tried on multiple drops, and there are other devices on those drops.
Does the ASA treat an object-group with a network-object containing a range of IP addresses as a netmask? For example, I can apply this configuration without the ASA throwing any errors though the configuration calls for a 'net mask':
object-group network test
network-object 192.168.0.0 192.168.63.255
?
network-object-group mode commands/options:
A.B.C.D Enter an IPv4 network mask
sh run ob id test
object-group network test
network-object 192.168.0.0 192.168.63.255
I found that in the documentation it requires a netmask as oppose to a range. Is this a bug in the code? I am running code version 8.0(5)23 on a 5520. If this is not a bug how does the ASA treat this type of configuration when applied to an access list? When I ran a quick packet trace and denied access from that range it looks like the ASA doesn't read that configuration properly.
We were using ASA-5520-K9 with ASA-SSM-AIP-20-K9 but recently found some hardware problem in our running ASA. Now cisco want to replace with ASA-5520-K8.

I have an internal address that I wish to forward from an external address- so if someone goes to 123.456.789.012:3456 then it will forward to 192.168.1.244:92 (All numbers are arbitrary here- only for illustration). I have and Access Rule and NAT and PAT set up so that I can get in if I originate from outside the LAN. What I am trying to do is to have this work from inside the LAN as well- so that if I am at my desk, and I connect a device and type in 123.456.789.012:3456, it will deliver the content at 192.168.1.244:92. The problem I am having is that it just isn't working, and I cannot figure out why- When I started here, there was an address configured to work this way, and it still works- I just cannot find what is different between what I am doing and what the person who configured it did.

View 6 Replies View RelatedI recently configured and installed a 1941ISR for a customer. The customer purchased a 25-User SSLVPN license with the router, and I configured it for remote SSLVPN access. This is working nicely except for one issue: when users initiate an SSLVPN connection request by browsing to the assigned webvpn gateway IP, they get the "There is a problem with this website's security certificate" browser message. They are in the process of working with their DNS hosting provider to get a DNS entry assigned to the IP address so the users won't have to specify an IP address in the URL address box, but they will continue to get the certificate error until/unless I can figure out how to resolve the issue.
I've tried the following "How to make IE8 trust a self-signed certificate in 20 irritating steps" that I found via another forum link but with no luck:
1.Browse to the site whose certificate you want to trust.
2.When told "There is a problem with this website's security certificate.", choose "Continue to this website (not recommended)."
3.Select Tools->Internet Options.
4.Select Security->Trusted sites->Sites.
5.Confirm the URL matches, and click "Add" then "Close".
6.Close the "Internet Options" dialog box with either "OK" or "Cancel".
7.Refresh the current page.
8.When told "There is a problem with this website's security certificate.", choose "Continue to this website (not recommended)."
9.Click on "Certificate Error" at the right of the address bar and select "View certificates".
10.Click on "Install Certificate...", then in the wizard, click "Next".
11.On the next page select "Place all certificates in the following store".
12.Click "Browse", select "Trusted Root Certification Authorities", and click "OK".
13.Back in the wizard, click "Next", the "Finish".

15.Dismiss the message box with "OK".
16.Select Tools->Internet Options.
17.Select Security->Trusted sites->Sites.
18.Select the URL you just added, click "Remove", then "Close".
19.Now shut down all running instances of IE, and start up IE again.
20.The site's certificate should now be trusted.
I followed all 20 irritating steps to the letter, but am still getting the security certificate nat.Now when I “Continue to this website (not recommended)” and click on "Certificate Error" at the right of the address bar, the certificate error windows says “Mismatched Address”.Is there a way that I can get this fixed without resorting to a 3rd party CA?

I recently switched routers to the DIR-615 and I'm trying to troubleshoot why one of our laptops keeps losing the IP address and gets a self-assigned IP address.

View 9 Replies View RelatedWe have an ADSL connection and use a D-Link DSL-320B modem. We have a D-Link DIR-120 router connected to this modem. This has worked perfectly fine up until today when we disconnected the router and connected a computer (call it A) directly to the modem because it was getting an unusable connection through the router for some reason. We later also performed a factory reset on the DIR-120 router.
Unfortunately, after the above steps the router did not receive any IP address (through DHCP) from the ADSL connection anymore. During my attempts to debug this I noticed that my laptop (call it B) didn't get any IP address either (when connected directly to the modem). I noticed the following syslog entries repeating over and over while trying to connect: [code]
At this point computer A could still get a connection just fine tho (when connected directly to the modem).
I then tried to change the MAC address of the router to an arbitrary one (a copy of computer B's MAC address but with the last digit increased by one). The router still did not get assigned any IP address. Finally I tried making the router clone the MAC address of a third computer (call it C). C has never been connected directly to the modem. Doing this worked. After cloning the MAC address of computer C the router is immediately assigned an IP address and the internet connection works as it did prior to all this.
Now, my question is, why would computer B and the original MAC address of the router not be able to get an IP address while two other computers worked just fine? Why would changing to an arbitrary MAC address not work while cloning the MAC address of another computer did? Could the router's MAC address have been blocked by the ISP for some reason (and what could cause this)?
but my situation seems more like a blacklisting of some MAC addresses rather then allowing just a single MAC address.
I need to change the ip address on my router same ip address as myDlink router?
