I have a really poor internet connection on ASA 5520 after creating a Redundant Interface with interfaces 2 and 3. As you can see, something is really weird:
Interface GigabitEthernet0/1 "", is up, line protocol is up
Hardware is i82546GB rev03, BW 1000 Mbps, DLY 10 usec
Auto-Duplex(Full-duplex), Auto-Speed(1000 Mbps)

I bought my Inspiron 15R 5520 yesterday evening. Today when I was using my laptop on wireless network then I realized that it's very slow. Then I used application speedtest.net to check the download speed, it's just 9.09 Mbps instead my old HP laptop was receiving 43 Mbps.
I have Network Adpater : Intel Centrino Wireless N 2230 having version number 15.5.7.52 which is latest.
I have two 5520s in a failover configuration. When browsing the internet behind them the speeds average 0.5Mb/1.0Mb Download/Upload. When bypassing the ASAs the speeds increase to 4Mb/6Mb. I have checked the interfaces on the ASAs and there are no errors, collisions, drops, etc.
View 7 Replies View RelatedOur internet connection is connected to an ASA. The download speed is ok but the upload is very slow. we have been running some speed test from our LAN, and have been also trying to upload/download file.
Our ASA also have the IPS module. I turned this off but we've got the same result.
I send here attach the configuration file of the ASA.
I have problem with my Internet connection. Recently my Internet connection often get slow. There are 3 connections on the server running Windows Server 2003. 1st is External, 2nd is Internal and 3rd is VPN (please see attahement). There is nothing to do with External and Internal connections, and everytime the Internet connection get slow, I have to disconnection VPN (connection) and connect it again.

We are currently using Cisco VPN Client. I'm looking to migrate to Cisco Any Connect. Our ASA 5520 has 750 IPSec and 2 SSL license. I also have approximately 40 IPSec site to site VPN's on this. ,Will anyconnect interfere with the site to site tunnels?,If I setup anyconnect with the IPSec instead of SSL do I still need to purchase the premium or essentials license?,Lets say if I do have to get the license and I get essentials will it cause any issues with the site to site VPNs?
View 2 Replies View RelatedI have a problem with the connections to the remote webservice passing through ASA 5520 firewall. Connections are usually interrupted in perod of half an hour in every few days.
This ASA 5520 firewall is only one firewall in a path to the remote webservice.
During the interruption I find the logs:
UTC: %ASA--4-419002: Duplicate TCP SYN from dmz1:x.x.x.x/.... to outside:y.y.y.y/p with different initial sequence number
Teardown TCP connection 28309406 for outside:y.y.y.y/p to dmz1:x.x.x.x/.... duration 0:00:30 bytes 0 SYN Timeout
How I could find root cause? Could it be solution implemetation of TCP State Bypass?
I have a VPN tunnel between my ASA 5520 and another device.The tunnel is up and there are no problems in that. I have a SIP device behind my ASA and anther one behind the other device (no specific details about the other side since it is with a client).I have allowed the (ICMP & IP) traffic to pass through the tunnel, and I successfully can ping from my SIP the client's SIP through the tunnel.When I try to make a SIP call over the tunnel it fails.After troubleshooting I found the bellow results:
1- the traffic never go through the tunnel (the number of packets are not increased when I try to make a call although it in increased when I ping the other side)
2- When I made a test using the ASDM (Packet tracer) the result is successful (the traffic is NATed and allowed (passed the access list) and goes through the VPN tunnel).
3- the below result are the output of the logging of my ASA:

We 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.

I am not able to access the device via SSH .After connecting to teh console I have found that allowed SSh session are fully utilized with show resource usage command and the output is [code]
So I used show ssh session command to see who is using the sessions but in the output it has showed only one session and the output was [code]
I was wondering why it shows only one session above instead of showing all the 5 sessions which are utilized as confirmed by show resource usge command.We are usning some internal tool for ssh monitoring on device which is poling the device after a fixed interval for port 22 reachabilty .I dont think these tools are making any issue as this is secondary firewall and we are not facing any reachabilty issue for primary firewall.also we are using 10 min for idle ssh timeout.
I configured multiple vlan on my Cisco ASA5520. Everything work perfectly except RDP (3389) connections. The connections are established but but after a period of inactivity, the user is disconnected from server (black screen). The same problem happens with other type of connections (client/server), exemple : Oracle, file sharing. Before installing the ASA, computers and servers were in the same vlan and it worked well.
There's a notion of inter vlan timeout connection ?
I have a Cisco 5520 cluster and Cisco Anyconnect Secure Mobility Client 3.0.5080. I eventually want to connact by means of a Smard Card and I was able to connect a view weeks ago. Now I am hastled by the error Logon denied, unauthorized connection mechanism, contact your administrator. Well that's me and a do not know anymore where to look on the Asa. I thought it had something to do with the authentication method, but AAA (AD or Local), nor cetificates is now working.
Cisco's solution...:
Error: "Login Denied , unauthorized connection mechanism , contact your administrator"
AnyConnect clients are failing to connect to a Cisco ASA. The error in the AnyConnect window is "Login Denied , unauthorized connection mechanism , contact your administrator".
I have attached setup like this :- This is the same scenarios as ASA with Dual WAN setup. But my requirement is different. I have added in ASA and configure sla is asa, all working fine. When one link goes down traffic pass through backup route. my sal config is below:-
sla monitor 100 type echo protocol ipIcmpEcho 10.5.5.120 interface Link1
num-packets 3 frequency 10
sla monitor schedule 100 life forever start-time now
show runn routes are :-
route Link1 10.5.5.0 255.255.255.0 10.4.4.5 1 track 10
route Link2 10.5.5.0 255.255.255.0 10.6.6.5 254
Is there any way that i can implement track on 2nd link to destination? because may be after Link1 failure when backup route was it would be able pass traffic to destination, may be link failure between Link router and Destination. Can i monitor backup link if that is active and traffic can pass to destination when 1st Link1 will fail.
i am using Dell inspiron 5520

We have a 4mbps unlimited connection and the internet speed which is connected via wireless to 2 systems, is good in one system out of two. the connection in one alone is very slow i mean dead slow.
View 2 Replies View RelatedFor the past two weeks or so, my internet connection on my pc has become extremely slow(from 200kb to 10). Not only has it gotten slower, i also cannot download anything without the connection stopping. The problem, i believe began a couple months ago with just youtube videos streaming slower and downloads stopping ever few minutes, but until these past two weeks its never been that much of a issue. I know the problem is isn't my dsl because it works fine with other internet capable electronics so it must be a software/driver issue.The svchost uses up 100% of the CPU when something tries to update so it likely might be a windows based program acting up.
View 7 Replies View RelatedMy basic question is, does Cisco VPN Client allow two simultaneous VPN connections at once?I want to set up the following:User Client (Remote Access VPN via Internet)--> Head Office ASA 5520 A/S Pair --> (Remote Acces VPN via Internet) --> Branch Office ASA 5510S+ A/S Pair,So, in order to access the branch office system, the user must:Connect to Head Office ASA peer via Cisco VPN Client (user/password authentication),Head Office ASA peer gives a private 172.16.1.x IP, and is configured to route all requests to Branch Office's public ASA IP via it's own public IP address. Once Head Office VPN established, user establishes a SECOND VPN tunnel from Cisco VPN client (user/password and cert-based auth).

View 1 Replies View RelatedWe are working with an ASA 5520 and it seems there is an issue with some email messages sent throught it. When there are many recipients in the emails the email messages are not sent, and I have revised the server an the only thing I see is connecting dropped. When I went to see ASA log and see this log report: ESMTP Classification: Dropped connection for ESMTP Request from 'interface': servername/portnumber to outside: IP address/25; matched Class 2: cmd RCPT count gt 100 tcp flow from interface:servername/portnumber to outside: IP address/25 terminated by inspection engine, reason - inspector disconnected, dropped packet. So I think there should be an inspection of ESMTP packets and if they detect an email message sent to over 100 addresses, then the packet is dropped, am I right? if so, what should I do to let those email messages be sent?

I have delete the VPN IPSEC but it's still not working and I have the network down
I have my router connected to my ISP, but for some reason I am getting really slow internet connection compared to a home Linksys router. I can only think it may be to the fact my port is set to auto speed and auto duplex.
Sometime the websites are fast, other times slow. Cannot seem to pinpoint the reason since my code is so basic.
cisco E3200 wireless connection slow.
View 1 Replies View RelatedI'm an IT professional with more than 10 years experience. I have spent last 5 days trying to figure out why the wifi connection to this router is so slow, but still no luck. I'm getting only 13Mbps even if my laptop is next to the router! (wired connection worked ok)
I have tried all sort of setting combinations, 2.4GHz/5GHz; N only/ G,N Mixed; Auto/20MHz bandwidth; different channels; WPA2 encrypted vs open; disable firewall; wmm enabled/disabled; 1.0.0.26/1.0.1.0 firmware... no matter what I try, I always get only 10 - 15Mbps speed.
Once I replace this router with my old router, it worked perfectly --- getting 70 - 80Mbps with exactly the same testing environment and configuration.
I really expect this router to offer much faster wireless speed according to this review: [URL]
a customer is running ASA5505 and they have a cloud server behind site-to-site VPN tunnel. They are complaining that FTP transfers are very slow (3-4MB) and the connection goes down very often. They are transfering large (3-6GB) back-up files and ISP connection is 100MB fiber.The problem is not the speed, but that FTP fails to transfer the backups. I recommended to drop MTU size from 1500 to 1430 from the server side, but it didn't seem to work.
Basic info about the tunnel:
P1 Diffie: Group5
P1 Enc: 3DES
P1 Auth: SHA-1
P1 Lifetime: 28000

I think I might have a problem with how my network is set up.
Cable Modem --->ASA5505--->Cisco 3660--->Switch For some reason if I use the ASA as a DHCP server too, the internet is much faster. Could the 3660 be slowing down the netwok? The 3660 has 2 FE ports, so it should be running good at 10/100 correct? Is there another setup I should consider to speed up the network? [code]

When I use the wireless connection the "Connection Status" shows as 72Mbps, which is to be expected considering I am only a few feet from the router.the speed is nothing like that in reality. I tested the actual transfer speeds for the wired and wireless connections by copying a 238MB folder with 77 photos in it. I copied it from the NAS device, where I store all my files, to the local disk of the netbook.
