I'm trying to establish a site to site ipsec tunnel between an ASA 5520 and a Nortel Connectivity box. Despite trying a number of different transform sets and IKE setups it keeps failing at phase 1 with:
Information Exchange processing failed
Received an UN-encrypted INVALID_ID_INFO notify message dropping.
I've just completed a port security project at a site on numerous Cisco switches and all works well, however they have 2 Nortel 5520 switches (which I left until the end) which they would like to lock down. I have logged a message on the Nortel forums and I have heard nothing for days. I just need to lock 2 ports down to the Mac address of 2 computers stopping any other computer being plugged in.
View 2 Replies View RelatedI have a customer that wants to change their Nortel 5520 switches to a Cisco solution, and I wanted to ask what would be a good solution for this customer. presently they have 4 48 port PoE and 2 24 port PoE stackable 5520, and they are interested in redundant power supplies for the switches. I was thinking that the 3750 is good for this site.

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.
We have AT&T Managed MPLS service are our datacenter and our branch office locations. AT&T has provided the routers and simply give us an ethernet connection. We also have ethernet connectivity to the internet through our datacenter...with our network being protected by an ASA 5520.Each branch location has a 29xx series router (voice gateway) and switching gear attached to their AT&T MPLS router. Some of our branches also have 3rd party cable internet service with an ASA 5505 to protect it from the internet. What I'd like to do is better utilize this cable modem/ASA5505 setup. Right now, if there were an outage, I would be connecting manually to the remote location to change static routes to point to the cable link and to configure a VPN tunnel between the remote and our DC.

I'm working with AnyConnect for the first time (my prior experience is with IPSec client) and I have multiple remote users who connect to a 5520 via AnyConnect client; they need to print to each others' shared printers but currently have no connectivity between each other.
Can I configure the 'intra-interface' command to enable connectivity between remote clients, or is there more that needs to be done to enable this, presuming that it can be done at all?
I purchased a new N600 dual band router (2.4 and 5.0 GHz). I set up security to use WPA/WPA2 PSK (AES) on both bands. The devices that can see the 5.0 band could connect without issue, however those devices that can only see the 2.4 band (older devices like the Nintendo Wii, my desktop computer with wireless, and iPhone 4's could not connect). In troubleshooting, I finally disabled security on the 2.4 band and everything connected without issue, but I cant figure out how to successfully enable security on both bands at the same time.
View 1 Replies View RelatedI have a project to upgrade an ASA 5520 to 9.1.x, then add another ASA for failover. What will be the correct way ?
I had the 2 Gb memory.
I have rewritten all nat statements (during my other 8.2 to 8.3 or 8.4 upgrade project, the nat conversion was catastrophic, so I rewrite all now).
Can I upgrade directly to v9 ? Or 8.2 -> 8.4 -> 9.1 ?
I think to :
- inject actual config in the new ASA in 8.2
- remove nat statement
- upgrade to 8.4
- configure new nat
- upgrade to 9
- connect the new ASA to the network and deconnect the other ASA
- test
- upgrade old ASA to 8.4 or 9 directly ?
- configure failover
Do I need the security plus license to do HA with two 5520's?I was told by our purchasing department that the 5520 was supposed to be able to do HA out of the box, but when I look I see only the VPN + license. Does that mean I can download the security plus license? Or do I even need it on the 5520.
View 2 Replies View RelatedI have an ASA 5520 running 8.0(3) with two Subinterfaces configured like this:

(notice that they have the same security-level)I need to control the traffic between them with ACLs so I in ASDM unchecked "enable traffic between two or more interfaces with same security level" and "enable traffic between two or more hosts connected to the same interface"Now I cannot ping from one Vlan to the other, as expected,,, but I tried many different ACLs and I cannot ping or telnet to the other side from either one.
I have a SSL certificate from a third party that is showing under the Identity in ADSM, howerver the audit scan of the firewall shows that the SSL Certificate Signed with an unknown certification Authority. I have installed the Intermediate Primary and Secondary Certificate from the third party under the CA Certificate of the ADSM however when I verify the SSL certificate it still shows as self-signed. What other steps do I miss. I have attached some screenshots.
View 2 Replies View RelatedI have a DMZ (50) from where I need to allow some protocols to inside zone (level 0). I am doing that with ACL, but after having done that the implicit security level rule to lower level (outsite level 0) is not working anymore, I guess by the implicity deny after the acl. I'd need allow traffic to the outside zone from DMZ, as well as the inspect traffic from the inside one. Is there anyway to have both ACL and Security levels?
If not, what do I need to do to just allow some protocols going to higher level and leave the higher-to-lower traffic inspected allowed, same schema as we have with security levels.
We have a ASA 5520 which is configured to send log files to an ftp server. It has been doing that until recently I found out that it stopped sending the logs on August 11. I can't remember what I have changed in the ASA config to make the ftp stop. I changed the ftp config to another server but it won't upload any log file.
What can I do to make the ASA save the log buffer to the ftp server again?
On a Cisco ASA 5520. I have 2 interfaces that are the same security level. I need hosts on 1 of these interfaces to be able to get to a specific IP and port on the other but I DON'T want to blanket enable 'same-security-traffic permit inter-interface" I have added an ACL inbound on the interface allowing the desired traffic and inbound on the other for return traffic and it simply doesn't work.
interface GigabitEthernet0/3.175

I tried to access server from THREE network to web server at FOUR network I have no response. In sh xlate output it shows "PAT Global 10.124.104.254 (28889) Local 10.124.103.1(2922) " I am not sure what else should I do. I add both same-security-level commands and it is the same.
We have two multilayer switches and only one ASA 5520. I'd like to connect ASA in the way described on the picture: each redundant interface includes two physical ones, which are connected to different switches
My question is what kind of link it is necessary to have between switches to make this idea work? I'd have subinterfaces like Re1.100, Re2.200 and so on for my traffic.
I understand that correct design approach is to have two redundant firewalls with failover but we cannot purchase the second one yet.
I recently configured WCCP with a Sophos Web Filter on my network it works good but the problem I am having is I have two 5520s so I am directing the device to look at 2 different IP addresses and since the devices are in an Active/Passive failover. The problem is because the second device is in a passive failover it is not responding which is throwing connection errors to my Sophos device. I know you can have a single management connection for the ASA's but is there a way to have a single IP for the ASAs for the WCCP?

View 4 Replies View RelatedI have a ASA 5520 upon which I need to build a WebVPN for the company urls - webmail, intranet portals etc. There will be 2 groups -
a. Confidential Access - For senior management.
b. Public Access - For employee access.
RSA Token & LDAP auth would be used for access to the WebVPN. However, I am unclear on certain aspect.How do I isolate the 2 groups? I mean only Senior management should be able to view & access the first set of links while employees see and access the other set of links only.Both the groups will be available to all users loggin on to the WebVPN. Since the authentication mechanism - LDAP - is the same, anyone would be able to access the groups and in turn, urls.
Ive got a virtualised firewall running 3 security contexts in routed mode. What am experiencing is that i cannot connect to an OUTSIDE host through the security contexts. From the firewall itself i cannot ping the directly attached host on the OUTSIDE interface but i can ping the directly attached host on the INSIDE interface. When i reload the firewall box, the first ping to the OUTSIDE host would be successful but subsequent pings fail and thus total connectivity is lost.
I even tried upgrading to ASA version 8.4(1) but still the same.
I was unable to access my ASA 5520 using HTTP/HTTPS even on the management interface. I had upgrade the ASA IOS to asa832-k8.bin and ASDM to asdm-634-53.bin. But, the issue still the same.

View 2 Replies View RelatedWe are a business partner of a larger company that gives us a VPN access to connect to one website. It's the Nortel VPN so it's old but it's set to disconnect our Internet when we connect which is really inefficient. I understand why it does that but right now we use two computers, we have one as our main one then another sitting here just for VPN.Does the Nortel VPN work system wide when it disconnects the Internet? Or is there a way to use Ethernet and Wifi and just have the VPN connect over Ethernet and just disconnect the Internet there but keep my local network on Wifi? Or is that not possible? I'm assuming it's not just wondering if there's any alternatives.

View 0 Replies View RelatedCurrently using Cisco ISE 1.1 to authentication both dot1x and mab from Cisco switches. Both features are authenticating properly.When we use a Nortel/Avaya switch for the authenticator, we are unable to authenticate using mac bypass (non-eap (or neap) in Avaya talk..). The correct authentication policy is found in the ISE, but the mac address is not found in the database. We know it is there because the same mac is authenticating with the Cisco switch. Dot1x authenticates properly from both the Cisco and Avaya authenticators. Could this be an issues with the username/password format in the Radius packet from the Cisco?
