View 4 RepliesI am using site to site vpn with ASA 5550 and some users telnet to a unix macine on the the other end.
the problem appear if the session is ideal for 30s,
Our users are using Xmanager to connect to a NNM connection which is going through a Cisco ASA5550 with 8.3. The session of Xmanager is getting terminated exactly after 1 hour and the users have to reconnect it again. How can we make the session to be up always, when I am bypassing the Firewall its always up.

It was now possible to catch the error message - the output of show cpu usage looks like on the attached picture.We did not found something in the know bugs neither in the "Resolved Caveats in ASA Version 8.4(4.1) ".

So i decide to turn off my wifi and see what happens, there has always been this weird wifi connection appearing whenever my wifi appears, then afterwards when i turn off my wifi the suspicious wifi connections disappear. is this possible that someone is using our wifi? i might just be overreacting but it has brought me to concern that if the usage continues my family will have to end up paying over $30 for extra internet use. it is very frustrating me because when i check my DHCP client table it only shows 3 connection, ethernet - my desktop which is not turned on, 2 wireless connection - my laptop and my sister's laptop.
View 6 Replies View RelatedI'm trying to setup a tunnel from our Cisco 5520 to a 5550 using one of our external ips natted through this tunnel. For some reason traffic that should hit this tunnel goes through global nat. Here is the configs I have for this tunnel:
access-list policy-nat extended permit ip host 66.77.88.170 host 1.2.3.4
access-list Outside_cryptomap_60 extended permit ip inside-network 255.255.254.0 host 1.2.3.4
access-list Outside_cryptomap_60 extended permit ip host 66.85.99.170 host 1.2.3.4
[code]...
If I ping 1.2.3.4 from a inside ip host I see in the logs that it uses 66.77.88.136 as the NAT and not 66.77.88.170. Do you see something wrong with this configuration?
I have ASA5550 ruuning Version 8.3(1) with inside and outside interfaces as below [code] On the inside : I have a server (10.20.10.36) that need to be accessed from an outside host (Y.Y.131.34) , so I have the below NAT/ACL rules. [code] is it right that I have to add two ACL entry for outside host to the NATed IP of the inside server , then again add another ACL entry from the same outside host to the private IP of my inside server o get this communication done?

I thought maybe i could disable IPSec for those profiles, but since the IPSec is an attribute for Group Policy, i cant do it - as many other profiles are sharing the same policy.
View 2 Replies View RelatedIn our company we use ASA 5550 as a VPN server (failover pair, FW 8.2(5)). Long time we used Cisco VPN client (easyVPN) only and some time ago we started to use L2TP/IPsec VPN from Windows clients.From this time we can see strange behavior. Some ip addreses (we use ipv4 only) from local VPN ip pool are getting unusable for clients. When client gets this ip address the traffic from client to intranet is ok but the traffic from intranet to the client is blocked. This behavior affect both L2TP/IPsec and easyVPN clients with this ip address.The packet trace shows that the traffic will be blocked because implicit deny ACL but ACL for the connected user is created:
Phase: 10
Type: ACCESS-LIST
Subtype: vpn-user
Result: DROP
Config:
Additional Information:
[code].....
We use RADIUS for authentication and ACL. Failover to the standby ASA solves the problem but this terminates all L2TP/IPsec VPN connections.We use Cisco Anyconnect VPN too and when Anyconnect client gets this „strange“ ip address he can communicate normally without problems. It looks like that this problem is related to IPsec. how to discover why ASA uses -implicit deny- instead of user ACL?
If my ISP brings ethernet into the building via duplex LC multimode fiber can I use the ASA5550 as the first device from the WAN or do I need some type of router for this? I realize I'll need an SFP to get to duplex LC, but I'm not sure if I need a router, or if the ASA can function as a router for this application.

2 interfaces from each slot are being used ie 0/0 for Branch users comming via MPLS cloud , 0/1 for internal LAN users comming form Core Switch & 1/0 for Server farm LAN , 1/1 for Internet (outside)
the first 3 interface are considered inside with sec set at 100 while the 1/1 is outside with sec at 0.
Last night it suddenly started dropping all connections without any warning or any noticible log form the ASDM logging.
the connection drop would happen for 2 - 3 minutes and would work fine for the next 15 minutes or so..
after conencting the console , we found out that the IOS would suddelny go abrupt and show this display ...

Currently on internship in a multi-site company, I am studying the IPv6 transition.I have to perform several tests and i was wondering if is it was possible to make a Site-to-Site IPSec VPN with IPv6 between a Cisco Asa 5550 and a Cisco 881 router.
View 17 Replies View RelatedI have looked in the books I have (Cisco ASA, PIX and FWSM; ASA 8.0) and googled a good bit but can't seem to find any specific mention of how to do NAT exemption with v8.4. It seems NAT exemption (NAT 0 access-list) was deprecated. Using ASDM, there's no corresponding menu item for this that is obvious.
We have public addresses inside the ASA and want to allow in/outbound connections using these IP's without NAT. The ASA is a 5550.
I need to understand if ASA 5550 ver 8.2(1) is comptible with IPv6, if not what is the upgrade path to make it IPv6 compatible. The requirement is dual stack of IPv4 and IPv6 should run in the same HA cluster and later will shift IPv6 completely.
The existing infrastructure is equipped with ASA with HA Active/Active mode. The command output for required details are attached here in txt mode.
I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
1. The ASA hardware was haivng problem
2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
Downgrading any license (for example, going from 10 contexts to 2 contexts).
# Note If a temporary license expires, and the permanent license is a downgrade, then you do not need to immediately reload the security appliance; the next time you reload, the permanent license is restored.
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
I am not sure what could be the issue that the servers in the DMZ wen unreachable.
In my Cisco ASA 5550, I need to set two different syslogs servers, and I need to send the system logs to the first one (only admins login/logout), and the traffic logs and all the rest (informational level) to the second one. Do you know if is it possible or not and, if yes, how to configure it?

View 1 Replies View RelatedI am using an ASA5550 for a complex secure network that has at least six "outside" networks. Each "outside" network is assigned to a specific port each set at level "0". I also have a DMZ, set to level "50". I am having difficulty with passing traffic from a host in the DMZ to all but one of the "outside" networks. Is there a limit to the number of "outside" interfaces? I will provide a redacted config file as soon as possible.

I have the following problem, right now we have an ASA 5550 connected to the client´s side. A reset is being received on the client´s side, but when we run the sniffers on both extremes of the network, we can see that the reset is not being sent by the server´s side.
We have narrowed it down to the 5550 ASA, but have found no bug that matches the description.
The characateristics of the reset packet are the following:
- It is the only packet with a TTL of 255.
- Both server and client have very different window sizes, and the reset packet even though has the server´s ip and port as source of the packet, it has the client´s window size.
- It has a correct ack number.
-Before the reset is received, there are a couple of retransmissions of the last packet sent.
- We´re handling a VPN tunnel between both servers.

i'm installing a Firewall Cisco ASA 5550 with 8 Gigabit interfaces.
I have installed firmware 8.2.3.
Is it possible to make link aggregation on ASA to have more bandwith?
I have a couple of ASA5520 and ASA5550, and I wanted to know if it is worth it to upgrade the software from 8.2(4) to 8.2(5)? Because of the RAM I cannot upgrade to 8.3 for now.

I've got a pair of 5550s running 8.3.2 in active/standby. Based on the following license configuration, what do I need to support mobile clients? Anyconnect for mobile is obvious. Essentials? Since changes in 8.3 can I get away with one anyconnect for mobile license or do I need one per firewall? How many mobile clients would I be licensed for, 2500 per firewall? [code]

94097614769 packets output, 59002295942465 bytes
999339444 packets dropped
My interface is 1GB, based on the above command, it is full?If interface is full, i have a problem! All the ports on asa firewall are using, how do resolve this? I can compress all data on this interface with class maps and policy maps?
We are having Cisco ASA 5550 appliance. from some days i am not able to access this ASA using ASDM. I am able to access ASA using SSH.[code]
At the same time standby firewall works perfectly fine with ASDM. I have tried by reloding the firewall, then it worked for 2 days & again stopped working.
Is it possible to use ports from 2 SFP and 2 RJ45 Interface on ASA 5550 Module 1.
