CISCO ASA 5520 telnet
I have a CISCO5520 and telnet has suddenly stopped working on my inside interface.
I checked my syslog error and get the following
5 | October 15, 2013 | 11:56:02 | Resource 'telnet' limit 5 reaching for the context "single_vf". |
No idea what this could be?
Thank you

Is supported PPTP vpn cisco ASA 5520 firewall?
Hi all
I'm Md.kamruzzaman. My compnay buy a firewall of cisco asa 5520 and I want to configure PPTP vpn on asa 5520 firewall. Is it possible to configure the PPTP vpn to asa firewall. If possible can you please tell me what is the procedure to configure the PPTP vpn.
Best regards
MD.kamruzzaman
Sorry, but the Cisco ASA firewall does not support PPTP VPN termination.
You may terminate IPSec and SSL VPN but not of type PPTP.
If you are new to the ASA, how best to configure the supported VPN types is via the VPN Wizard integrated into the application of management of ASSISTANT Deputy Ministers.

Routing with Cisco ASA 5520 VPN
I have installed IPsec vpn remote users in the Cisco ASA 5520 using RADIUS in my main network. Works very well. I have a site to my Cisco ASA5520 tunnels going to other sites, some of the tunnels have Cisco ASA and some have SonicWalls. I wish that my users VPN remote IPSec to be able to navigate in these tunnels is a site to access remote subnets attached to these tunnels. Do I need to use a combination of routing and the ACL? Or can I just use ACL only? Or just use routing only?
Thank you

Hello
The key to set up here is the two ACL of VPN L2L end points that determine the 'interesting' traffic to connect VPN L2L. You will also need to confirm that the connection of the VPN Client is configured so that traffic to the remote sites have sent to the connection of the VPN client. There are also other things that you should check on your ASA plant
Here most of the things you usually have to confirm
- Set up 'permit same-security-traffic intra-interface' if it is already present in your configuration
- This setting will allow connections to form between the hosts that are connected to the same interface on the ASA. In this case, applies because the VPN client users are connected to the interface 'outside' of the ASA and also remote sites are connected to the ASA to "external". If the traffic between the remote VPN Client and VPN L2L sites will be to enter and exit the same interface
- You will need to check how the customer if configured VPN connection. Split or full Tunnel tunnel
- If the connection of the VPN Client is configured as Split Tunnel then you need to add all the networks from the remote to the Split Tunnel, so that the connections between the VPN Client is transmitted to the ASA and from there connections VPN L2L
- If the connection of the VPN Client is configured as full Tunnel, then there no problem that all traffic is transferred to the Client VPN connection all its assets
- Define the VPN pool in the ACL of VPN L2L
- You should make sure that the pool network VPN Client is defined in the ACL that define 'interesting' traffic to connect VPN L2L. So, you need to add the pool VPN VPN L2L configurations on the sites of Central America and remote control
- Configure NAT0 / NAT exempt for remote VPN Client to L2L VPN Site traffic at both ends of the VPN L2L
- You must ensure that the NAT0 / exempt NAT rules exist for the VPN Client for Remote Site traffic. This will have to be configured on the SAA "outside" interface. Format of configuration varies naturally a bit on the ASA Central his software level.
These should be the most common things to set up and confirm for traffic to flow between the VPN Client and Remote Sites
Hope this helps please rate if yes or ask more if necessary.

Upgrade to Cisco ASA 5520 8.2.5 to 9.1.7
Hello
I have an upgrade tonight for a customer to upgrade a StandAlone ASA 5520 in version 8.2.5 in 9.1.7. I have the same upgrade week next to the same client for a failover pair.
I already have this kind of process of 8.2.x upgrade to 9.1.x so I know the entire process, since I have to take a first step 8.2.5 8.4.6 then 9.1.7. In addition this customer has no statement of Nat therefore normally an easy process.
But today during my routine to prepare for the upgrade (I prefer to make a double or triple check before) I found this bug:
https://BST.cloudapps.Cisco.com/bugsearch/bug/CSCuh19234;JSESSIONID=0A69...
This bug is fixed in version 8.4.7, and 8.4.6.99. But it is not recommended by the upgrade process for a 8.2.5 to 8.4.7 jump and I can not find the 8.4.6.99 version.
I don't want to have any problems during my upgrade with something I can avoid.
As I said I already have this updated in the past without any problem and with a more complex configuration.
Has anyone as a return to this process for the last months? Should I do an extra step? (before first 8.2.5 to 8.4.5 8.4.6 or 8.4.7)
Thank you in advance for your answer.
There are a few incidents reported for ASA 5520 8.2.5 hit this defect running.
You can go for an extra for 8.4.x upgrade as you mentioned to avoid default we can't say for sure if you will encounter this situation or not. 8.4.6.99 can be a picture of development so be unavailable unless you want to call TAC and confirm or obtain any other image in 8.4.x train.
Maybe add another upgrade code can't hurt as that hit the bug.Kind regards

Addition of Compact Flash in a Cisco ASA 5520
I'm trying to install a 512 MB COmpact Flash for an ASA 5520 Cisco. We inserted the compact flash, but when we do a DIR, it does not show. even as an unformatted device.
What should we do to make this a usable CF? I just need to recharge the ASA or do I need to format the CF. It was inserted into the slot in the back of the ASA 5520, and we ensured that had been properly rests.
Thank you
Dwane
I can hot flash player? For example, is it possible to change the flash player when Cisco ASA is turned on and running?
It is always recommended that you turn off the Cisco ASA, while you insert the flash drive. This disables all working processes and allows the ASA to recognize the flash from the startup process.

Hello
I'm trying to get my ipad to VPN to our Cisco ASA5520.
I think I have all the correct settings on both ends (I am able to vpn to the asa using a cisco 871 as the remote client).
I think that for some reason the client vpn on ipad is not even make the asa. My question is: How can I monitor the ASA logs to see if the same connection attempt and eventually find the failure?
Thank you
M
try: -.
Debug crypto ISAKMP
Debug crypto ipsec
Vpn-sessiondb SH remote control (to see if the client is connected)
I have configured ipad for remote vpn client, the user could connect to the 5520 but why that I had to use the ip addresses to access, but I couldn't use internal dns names. try to understand that at this moment.
It may be useful

Cisco ASA 5520 cannot ping between VPN Tunnels
I have the main site and sites A and B. A to connect to the hand and B connects to the main. I can ping from A hand and has for main. I can ping from main to B and B to main. However, I can not ping from A to B. A and B are sonicwall 2040 and main is a 5520. The question should not be with the 5520 none allowing traffic between the two VPN Tunnels, but I can't understand why it does not work. Can someone give an idea on that? Thanks in advance.
Hello
I see that you use ASDM. Always makes my eyes bleed when I need to look at the DM_INLINE of named objects and try to make sense the CLI format
Seems to me that there are problems with the NAT.
If you don't mind a small break between the main Site and remote locations, I'd say changing some follows the NAT configuration
Remove old

Hello, my name is Jeremy Rose, I am a novice...
I'm trying to set up a VPN in a private network to access a server from outside of our firewall.
The VPN functions, however, we are unable to contact the server once the VPN is in place.
I can provide more information, as requested, any ladies or gentlemen reccomendations?
Thank you
Jeremy
Ensure that valuable traffic corresponds to both ends basically. So if your server is 192.168.1.10 and changed to 10.1.1.10 you must update under the card encryption ACL.

Cisco Anyconnect VPN and IPSEC coexist on ASA 5520?
Can a Cisco ASA 5520 which has been configured as IPSEC VPN gateway and also be configured as a gateway ANYCONNECT VPN and vpn IPSEC service anyconnect vpn clients clients maintenance at the same time? Any negative impact on the performance or any other problem that everyone knows?
I guess that by 2 connection limit, you are referring to the 2 licenses for anyconnect? You should consider using the anyconnect essentials license, which is relatively cheap (100-200 dollars I think) and will take you to the edge of the platform with anyocnnect.
You shouldn't have any problem using IPSEC with LDAP client. It is quite common - my company is IPSEC as Anyconnect off the coast of the same interface using authentication ldap (even same-group policy) for the two.

Normally exempt us VPN site-to-site of NAT traffic. This could be your problem. If you can share your configuration, we can have a look.

With an ASA 5520 port forwarding
Hi all
I recently bought a Cisco ASA 5520 on eBay for study and I decided to only use it as a firewall between my home LAN and Internet. Wow, what a learning curve! I managed to add my internal networks as objects and create a rule (thanks to youtube) NAT to PAT my internal devices out of the Internet with ASSISTANT Deputy Ministers, but I am really struggling to do the following:-
-allow all incoming traffic that hits the outside interface for port 38921 and nat at 10.1.10.101:38921
-allow all incoming traffic that hits the outside interface for port 30392 and nat at 10.1.10.101:30392
Can someone guide me on how to do it, because I have a couple of services that run behind these ports on a server I want to get when I'm not at home? My (rather messy) config is as follows:-
hostname FW1

Between Cisco ASA VPN tunnels with VLAN + hairpin.
I have two Cisco ASA (5520 and 5505) both with version 9.1 (7) with Over VPN and Security Plus licenses. I try to understand all the internet a traffic tunnel strategy VLAN especially on the 5520 above the 5505 for further routing to the internet (such as a hair/u-turn hairpin). A few warnings:
- The 5505 has a dynamically assigned internet address.
- The 5505 has sometimes no device turned on behind her, bringing interfaces down to the inside (which can cause problems from site to site).
- The 5520 cannot be a client of ezvpn due to its current role as a server of webvpn (anyconnect).
Let me know if I need to post my current config. Basically, I'm starting from scratch after several attempts.
Thank you!
- The 5505 has a dynamically assigned internet address.
You can use the following doc to set up the VPN and then this document to configure Hairping/U tuning
2. the 5505 has sometimes no device turned on behind her, bringing interfaces down to the inside (which can cause problems from site to site).
Make sure that the interface is connected to a switch so that it remains all the TIME.
3. 5520 the may not be a ezvpn customer due to she has current as one role anyconnect webvpn ()) server.
You can use dynamic VPN with normal static rather EZVPN tunnel.

disable the cisco ASA connection using only activate password via asdm
Hi all
How to disable the connection to my cisco asa 5520 using only activate password via asdm? I like to asdm connection using the user name and password. TIA!
The command:
aaa authentication http console LOCAL
.. .will be force users accessing to ASDM (which uses transport http (s)) to be authenticated on the LOCAL database.
You can also specify another list of defined authentication method, such as RADIUS, RADIUS or AD. (Although t wew love to leave a LOCAL method on the spot, in which case your external authentication server is not available.)
