Cisco VPN :: IPsec Encryption Proposal 5505
Dec 14, 2012I would like to know if I have only using IKEV2 to connect site to site VPN with Cisco 5505 device to connect few site. Which encryption method is better to choose with faster and stable IPsec encryption proposal,AES256, AES192, AES, 3DES, DES ?? which one is the best in IKEV2 site to site VPN tunnel?

Oct 29, 2012I've been troubleshooting this issue and was hoping to get some more feed back and maybe point out an error if I'm not seeing it. I recently setup a remote access VPN on Cisco ASA 5505. Everything appeared to work at first and the IPsec client connect. However if you look at the packets being encrypted an decrypted on the Client side only the encrypted counter is incrementing and the decrypted stays at 0. The opposite is true on the ASA side the decrypted continures to increment and the encrypted stays at zero. My first thought was maybe a mis configured NAT 0 statement or not defining the correct Split tunnel ACL but I have verified that. The asa version 8.2(5), I'll also list a packet-tracer I did from an inside host to VPN IP. [code]

Jul 20, 2011We have a situation where we need to encrypt the traffic on a Layer 2 V LAN. We have a Cisco Switch on each side but the fiber it runs over is leased and encryption (AES256 minimum) is required on a leased line. We have 2 ASA5505s that we could use on each side. Not sure what would be the best setup for this scenario (Site to Site). Or is there something better than using 2 ASAs on each side?

Dec 5, 2012I have an ASA 5505 without any IPS module.While copy/pasting some configurations from another 5510 with IPS I copied my mistake the some of the IPS configurations part. Now I can't remove it.When ASA starts I get this Warning:
...WARNING> IPS policy is configured without an SSM card.
*** Output from config line 828, " ips inline fail open"
Those lines are:
policy-map Outside_Policy

When I try to do "no ips inline fail-open" I get an "invalid input detected".If I try a no class IPS_class I get that is being in use.What can I do to clean up those lines?
Cisco Firewall :: Traffic With 5505 Goes To High To Low

View 4 Replies View RelatedCisco Firewall :: 5505 High Availability Over Dual WAN Connections
Mar 20, 2011One of my remote sites acquires Internet connectivity via a cable modem service. This goes down intermittently, of course. I would like to purchase DSL service from the local telco and configure the edge ASA (currently a 5505) to use the cable modem path normally ... and fall back to the DSL path if necessary.
These seems hard to do. The edge box would need to evaluate the viability of a WAN path using some set of tests ... perhaps pings to a handful of major Internet sites. If all those pings start failing, it would stall for a minute, to give the WAN service provider time to recover ... then cut over to the second path. Cutting to the second path might mean pushing new DNS server addresses to clients (or perhaps the edge box would hand out both sets of DNS servers all the time and rely on the clients to try them all.) Once the cable modem provider restored service, the edge box would stall for a while (ten minutes? an hour?) and then cut back.
I'm willing to replace the edge box with something fancier (a bigger ASA or something sold as a router or whatever), although I'd like to stay under 10K (list) for such a replacement.
Cisco Firewall :: ASA 5510 7.2.1 High Traffic On Outside Interface Very High Input?
Oct 13, 2011Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today. On the dashboard of our asa 5510 the "outside interface" traffic usage is running constantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.
View 6 Replies View RelatedCisco WAN :: 2801 High CPU Load / Low Traffic / High Interrupts
Nov 26, 2012We installed a solution with 2 Cisco 2801, BGP multihomed failover.
1) The router which is currently getting all the traffic gets to 55% to 60% of CPU usage when handling 40 SIP/RTP streams . This equals 10Mbit up/10Mbit down and it showed around 5800 packets TX and around 5800 packets RX, with a majority of them CEF switched. As those figures are way less than the performance figures published by Cisco, we wonder if we made any mistake in setting up our router, or if we can do something to improve the router setup.
2) Does it have an impact on router performance if we increase/decrease RTP packet size, thus increasing or decreasing the pps relative to the consumed bandwidth?
3) If it is not possible to improve router configuration, we also wonder about possible replacement units for those routers. Would a 2901 do a good job? By how much would it rise the capacity? What other models would you recommend if we plan to rise the number of concurrent calls by a factor of 4 or even 8 times of what we have now (so up to 48000 pps and 80Mbit).
Here is what we tried:
- ip route-cache same-interface does not seem to improve anything
- ip flow ingress on or off makes no difference
- disabling the inbound ACL on fa0/0 seems to reduce load by 10%, although I don't understand why - a very high percentage is CPU interrupts, and ACLs are process switched, or not?
- we tried following the Cisco guide for high CPU due to high interrupts, with no success
Here are some usage statistics:
The graphs that we plot via SNMP show a propotional growth/increase of CPU and bandwidth (and thus pps) At the highest loads, we had a bit more than 55% CPU utilization with more than 50% interrupt CPU.
CPU utilization for five seconds: 36%/30%; one minute: 30%; five minutes: 30%

Cisco VPN :: How To Downgrade To 2.5.3055 From 3.0.08057 On Mac OS 10.7.5 Lion
Dec 3, 2012I'm using the Cisco AnyConnect VPN Client (2.5.3055) to connect to a server "A". It has worked fine. Then I tried to connect to the server "B" from the free university of Berlin and then this installed (3.0.08057) automatically without asking. Connecting to server "A" does not work any more. The error message is: "The AnyConnect package on the secure gateway could not be located. You may be experiencing network connectivity issues. Please try again." So I tried to de-install the client with the shipped uninstaller and installed the previous 2.5 client again. but the Error message is still the same.so which files should I remove/edit to get it working as before. The network is OK, I tried it on a other computer under Windows Vista and there the freshly installed Client works fine. So I guess ther must be some files or configurations from the newer version in the way.

Feb 26, 2011i just thought i would try 1.35na firmware and i decided i wanted to go back to 1.33na, well you cant BE FOREWARNED.
i don't know what is the big deal about stopping you from downgrading your firmware that they lock you out of it. it never used to be a problem, pretty sure i could downgrade from 1.34na to other 1.3 firmware.
the reason for allowing people to downgrade is incase the new firmware does not work properlly. not allowing your customers to do this is just asking for trouble not to mention alienating your customers.
at work we downgrade firmware to the firmware that passed our quality tests, it also makes it easier to support them when they are all the same.
1.35 works well so i dont have to buy another router. if it doesn't you can be sure it wont be another dlink thats for sure.
D-Link DIR-655 :: Can't Downgrade From Firmware 1.35NA
Jan 12, 2011I purchased a DIR-655 (A4) a few weeks ago, and was encountering a problem. I immediately upgraded to 1.35NA after I bought it. First, the actual problem: With WMM enabled, my internet speeds are very inconsistent. By that, I mean it will fluctuate between full ISP speed and less than half the speed. A few seconds at full, a few seconds at half or less, and so on. Well, when I disable WMM, with everything else the same, the internet speeds suddenly become consistently fast at full speed, but PC-to-PC (LAN-to-LAN) wireless transfers slow down considerably. So no matter what I do I get a negative result.
Thus, I figured I would try downgrading the firmware to 1.32NA, 1.33NA, or 1.34NA, as I read that it is not possible to downgrade directly to 1.2x. I thought I would simply troubleshoot the problem myself. Unfortunately, no matter which firmware I try, except 1.35NA, it gives me a paragraph explanation; something like "This file was either not intended for this router, or it is corrupt. Your router will not be programmed." It did allow a reflash of 1.35NA, though. I downloaded multiple firmwares directly from the D-Link ftp multiple times, using a different router, so the files should not be corrupt.
Is it simply not possible to downgrade once you flash 1.35NA? For the record, I also tried a few of the workarounds I found on the internet: (1) do a hard reset by holding in the reset button and cycling power for 30 secs. (2) I tried some firmware directly from the German FTP which was supposed to allow a downgrade, but still got the same error as above. (3) I also tried some Russian firmware and it didn't work either. I was using a hardwired connection to the router during all attempts to flash.

Cisco Wireless :: Downgrade 3600 Capwap AP To Autonomous
Nov 12, 2012I have to prepare an 3600 Capwap AP for autonomous functionality!
The following image was downloaded: ap3g2-k9w7-tar.152-2.JA
The release notes say: Site-Survey Only Mode for 3600, 3500, and 1550 Access Points You can install Cisco IOS Release 15.2(2)JA on Cisco Aironet 3600 and 3500 Series access points and on 1550 series outdoor access points to perform site surveys. This release runs on these access points with limited functionality. You can manually adjust these settings on the site-survey access points:
• Channel on each radio
• Transmit power on each radio
• Enable and disable the radios
• Manually set basic and supported transmit rates
• Enable advertised cell power in beacons to client to enable DTPC for doing active surveys
• Enable and disable SSID broadcast in beacons
• Enable open authentication
My Question is: Where can i find a instruction for downgrading an AIR-CAP3602i to Autonomous 3600 AP? Is it complicate to get the AP running, or what do i need for "downgrading"?

Dec 25, 2012I've had the DIR-655 for a few months now, along with a Motorola Surfboard sb6121 DOCSIS 3.0.Modem works fine, the router was working perfectly fine until recently last week.
I have a desktop hardwired and a wireless network going on that I use just for my mobile phone and tablet at times. At first I was having disconnection problems with my wireless, then noticed a neighbor installed a similar router in the area according to my wifi analyzer, so I changed the channels and my wireless started working great. During this process I also did a firmware update and since then I've been receiving some really poor browsing problems, sometimes I'll visit websites like Facebook, or a news website, and it'll say something about the DNS not working, (at this point I'll ping the website and it still pings fine without any loss) so I'll visit the website about 10 minutes later and it works great. I've done extensive research on forums/Google and found it must link up to the new firmware update and something about a DNS relay? My version is: Hardware Version: B1 Firmware Version: 2.10NA
In other words, is there a way I can fix this issue from disconnecting without having to downgrade back to the old firmware? Or is this a common issue they'll continue to happen? If I do downgrade, HOW do I downgrade back to the stable version?
