SNMP configuration on ASA 5520

I was wondering if someone could provide me with basic configuration or a link to the basic configuration for the monitoring of SNMP on an ASA 5520.

Thank you

Chris

SSL VPN using ASA 5520 mode cluster - several problems

I configured 2 ASA 5520 s in the load balancing cluster mode. I connect using anyconnect and I download the customer the first time and everything works well except outlook. I don't know why outlook does not work.

The second problem is after the anyconnect client is installed on your machine, he remembers that ASA (say ASA2) he first connected and the GUI shows the address IP of ASA2 instead of the virtual IP address of the cluster. I want users always connect using the virtual IP address.

The third problem I have is there is a default group of SSL VPN and I want all users to use this group. In the initial web page, there is a drop down menu which shows that this group, but I still want to disable this menu drop-down.

Any suggestions?

To disable the drop-down menu, you can turn it off with the command

WebVPN

no activation of tunnel-group-list

This will take care of your last issue.

***************************

You can create a profile of the Anyconnect client with the name of the server you want to connect with and that make the ASA that will solve your problem of virtual IP.

**************************

Regarding Outlook, do you use specific ports which allows inspection of the ASA. Take a look at the list of inspection on the SAA and perhaps try to disable inspection and see if it works.

Multiple DMZ on ASA 5520 connection to a Catalyst 3550

I have ASA 5520 with 4 ports, I have 8 networks from the DMZ. As anyone configure an ASA 5520 for use with VLANS or sous-interfaces? How are you?

I plan to use interfaces on the DMZ interface and assign a vlan to each interface of void. Should I configure dot1q trunking on the interface of the DMZ. If this isn't the case, I'll have to set it up on the switchport to my DMZ switch? or does each subinterface * Just Thinking out loud *.

Thank you

Hi there on the physical interface first you won't have any config except for nonstop and up.then interface create secondary interfaces on the same interface as int I0.1. set the security level and assign them to one vlan and IP to make them.after which connect a switchport port and configure the port a port trucnking cause all traffic vlan of the asa will elapse of this port.on the button to connect your servers and assign the port to their VLAN respective and configure gateways thie as the ip address of the vlan configured on the asa. That's all. Incase you need more information. write again. If I solved it your problem then pls note the post.

VPN site to site & outdoor on ASA 5520 VPN client

Hi, I'm jonathan rivero.

I have an ASA 5520 Version 8.0 (2), I configured the site-to-site VPN and works very well, in the other device, I configured the VPN Client for remote users and works very well, but I try to cofigure 2 VPNs on ASA 5520 on the same outside interface and I have the line "outside_map interface card crypto outdoors (for VPN client). , but when I set up the "crypto map VPNL2L outside interface, it replaces the command', and so I can have only a single connection.

the executed show.

"" I thing both the force of the SAA with the new road outside, why is that? ".

without the road ASA pushes traffic inward, by default.

In any case, this must have been a learning experience.

Hopefully, this has been no help.

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:-

IPSec VPN to asa 5520

Hello

First I must admit that I am not very versed in Cisco equipment or in general IPSEC connections so my apologies if I'm doing something really good obviously stupid, but I checked through any kind of things that I could find on the internet on the configuration of IPSEC VPN.

The setup I have is an asa 5520 (o/s 8.2) firewall which, for now, is connected to a temporary connection beautiful style home broadband for testing purposes. The netopia router is configured to allow ipsec passthrough and redirect 62515 UDP, TCP 10000, 4500 UDP, UDP 500 ports in the asa 5520.

I'm trying to connein out of a laptop with disabled windows firewall and vpn cisco 5.0.02.0090 client version.

I ran several attempts through the ipsec configuration wizard options. most of the time that nothing comes in the newspaper to show that a connection was attempted, but there is a way I can set up product options the following on the firewall log:

I have connectivity full http from the internet to a machine inside the asa 5520 so I think that the static routing and NAT'ing should be ok, but I am pleased to provide you with all the details.

Can you see what I'm doing wrong?

Thank you

Pls add the following policy:

crypto ISAKMP policy 10

preshared authentication

md5 hash

You can also run debug on the ASA:

debugging cry isa

debugging ipsec cry

and retrieve debug output after trying to connect.

Tunnel VPN ASA 5520 (DMZ + INSIDE) destined for OUTSIDE

I can't find any reference to anywhere else.

We have an ASA 5520 to our site HQ (inside the network) with several regional subnets on the DMZ interface.

We need connectivity VPN Site to Site between the INSIDE and a remote control on the OUTSIDE of the site, as well as between the DMZ subnets and even outside the site. The interface from the OUTSIDE of the SAA must be local VPN endpoint for all tunnels.

I created a S2S VPN between the INSIDE and the OUTSIDE site and it works great.

When I create a VPN S2S tunnel between a site of DMZ and even outside the site (using the same settings the and remote, but with a cryptomap different because the local subnet (DMZ) is different from the other inside the subnet, the traffic gets the mapping (show crypto isakmp his) to the same cryptomap that was created for the access to the tunnel from the OUTSIDE) , instead of to the new cryptomap, so remote endpoint deletes it, and traffic also causes SPI incorrect of for the remote endpoint, which makes the original INTERIOR outside OF THE VPN tunnel to fall from time to time.

Is this a bug?

I also did a local S2S VPN tunnel configuration test of networks as everything INSIDE and the DMZ. With the help of the wizard VPN S2S leads ASA only to create a NAT rule exempted for the subnet on the INSIDE interface. Can I manually create another tax-exempt NAT rule to the side of the DMZ and use this a S2S tunnel to connect sites inside and DMZ to the remote OFF-SITE in a connection profile?

I'm building a Rube Goldberg?

Thank you

George

Hi George,.

It seems you have a situation overlapping it, are you sure that subnets inside did not overlap with the networks from the DMZ? A package tracer could clarify wha that the ASA is actually sending.

In addition, you can merge the two interfaces on the same card encryption if you wish, just make sure that the NAT is configured correctly. For example; Source NAT (all, outside) static...

It may be useful

The VPN is OK? ("' isakmp crypto to show his" should show a MM_Active tunnel to the peer address ")

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.

p.s. you should affect the question of the security / VPN forum.

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

ASA 5520 8.0 (4) port depending on the ACLs vpn works not

Hi all

I have a problem with an ASA (5520 8.0 (4)) for lack of working with a port based acl for remote clients. I have a simple acl from a single line to split traffic, if I allowed the tunnel IP works fine, if I lock it up to TCP 3389 rdp will not work. I don't see anything in the logs and debug output, I did have a problem with a similar configuration (5510 8.0 (4) and I'm at a loss to explain it.)

Everyone knows about this problem before? I have nat exclusions etc and as I said, the tunnel only works if the acl permits all IP traffic between client and server.

THX in advance

Split-tunnel list cannot IP, if you want to restrict which ports are are sent via the tunnel vpn for your clients vpn, you need to use VPN filters under Group Policy:

ASA 5520 and MPF

Hi all. In our company we have recently upgraded our PIX 515 firewall to ASA 5520, and we started to live a thing strange event. On one of the sites we host, I saw a lot of outdated SSM messages popping up and I think that they are the source of the problem when they surf the site (mainly surfing works fine, but sometimes people cannot content etc.).

I found the Cisco solution for this problem by using the MPF, but one thing confuses me. If I ask a MPF allowing adults MSS on the external interface of the ASA does this political conflict with the comprehensive policy that is on the SAA by default or can they both at the same time?

Thanks in advance for any help.

You can have a single policy per interface and another - global, that by default applies to default-inspection-traffic.

See http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/mpc.html for more details.

UPDATED TO VERSION 8.2 ASA 5520 TO 9.0

Hello friends,

I am planning to upgrade my ASA 5520 with version 8.2 to 9.0, so I'll enjoy the benefits of anyconnect for mobile devices. Clearly, I understand that I must pay special attention to:
- NAT rules.
- Memory RAM: 2 GB.
- Add references to the rule over the new versions for mobile and anyconnect
  
  L-ASA-AC-E-5520 =
  
  ASA-AC-M-5520 =.
am I missing anything else? Requirement of Flash? Or pay attention to some other configurations?

Any comments or document will be appreciated.

Kind regards!

You can run the latest version of the AnyConnect client - including mobile clients - with these licenses, even on a SAA with the current code of 8.2-8.2 (5) from now on. While it is a bit old and lack some of the new features, it is a strong and stable version.

That could save you the trouble to migrate the configuration of your NAT (and other songs) and the upgrade memory.

Since the series ASA 5500 (5510, 5520 etc.) is end of sales past you have a future limited on these platforms. For example, ASA 9.1 (x) is the last series of releases of code which will be available for them. (The current software on the 5500-X is 9.3 (1).)

Using Cisco Client to site VPN on a behind a NAT ASA 5520

I apologize if this has been asked and we answered in the forums. I looked, and while I found a large number of entries that were dancing all around this question, I never found nothing which addressed this specific issue. We currently use an ASA 5520 as the head end of a relatively large customer to site IPSEC VPN (approximately 240 users, not consecutively). This ASA is currently sitting behind a Checkpoint firewall with a real publicly addressable IP address on its public interface. All of our customers use the legacy Cisco VPN (not the one anyconnect) client. We plan to a few controllers F5 link set up between ISPS and firewalls. For VPN connectivity F5 recommends that we NAT IP address (called a broad IP) to point back to a private IP address on the ASA and F5. My question is, will this work? I've always heard say that the head of line needed to have a public IP address on this subject because this is what will be placed in packages for the client to respond to.

For further information, here's what we have now and what we are invited to attend.

Current

ISP - router - firewall-fire - ASA (public IP address as endpoint)

Proposed

ISP - router - F5 (public IP address as endpoint using a NAT to ASA) - Firewall - ASA (10.X.X.X as its external interface)

Proposed alternative

ISP - router - F5 (public IP address as endpoint using a NAT to ASA) - ASA (10.X.X.X as its external interface)

All thoughts at this moment would be greatly appreciated. Thank you!

Hello

If there is a static NAT one by one on F5 to the external interface of the ASA, then I don't think they would be any problems.
Because when the client will attempt to connect to IKE to the translated public IP, F5 will redirect the request to ASA outside interface that is configured for the VPN.

In addition, to ensure the udp500, 4500 and esp is allowed and then you should be good to go.

ASA 5520 - VPN using LDAP access control

I'm setting up an ASA 5520 for VPN access. Authorization & authentication using an LDAP server. I have successfully configured tunnel, and I can access internal resources. What I want to do now is to limit access to a specific ad group membership. In the absence of this belonging to a group, a user cannot access the VPN.

My VPN client software testing is Cisco Systems VPN Client 5.0.05.0290 Version. The Group authentication is configured in a connection entry that identifies the Group of Tunnel. I think I wrote that correctly.

The Version of the software on the SAA is 8.3 (1).

My current challenge is getting the VPN to stop letting each request for access through little matter belonging to a group. I found the thread below to be significantly useful, but there is obviously something which is not entirely mesh with my situation.

Hello

The configuration of what you are looking for is a feature called DAP (Dynamic Access Policy)

The following link will explain how to set up the same.

Problem connection ASA 5520 GANYMEDE

I'm just confused at this point. This is the configuration I have so far for the configuration of Ganymede on ASA 5520. SH run

aaa-server TacServer protocol tacacs+aaa-server TacServer (LAN) host 172.19.0.226key *****

user-identity default-domain LOCALaaa authentication telnet console LOCALaaa authentication http console TacServer LOCAL aaa authentication ssh console TacServer LOCAL aaa authentication enable console TacServer LOCALaaa authorization command TacServer LOCAL

route LAN 172.19.0.0 255.255.255.0 172.30.186.1 1

After that I was done with the Setup, I was able to connect using my username tacacas and the password you + activate password.

After that, I closed my GANYMEDE server + to try to the local database. It worked for the user name and password but my password enable does not work locally. Got to be something very simple and he had written down, I was connected via the cable from the console and also changed it was completely with the user name and password but still not able to go into enable mode.

After that failed I returned and turned on on my server TACACAS. When to wait a few minutes and trying to connect via tacacas NO GO. He doesn't like my username and password.

So now I'm locked out and have to do password recovery because I can not connect using tacacas, and when tacacas is off I can not go in the local mode.

Very litle documentation cisco out there for this issue... Any thoughts what coukld be the cause? I know that GANYMEDE works very well since he works on 500 + devices, I'm just confused at this point.

I need to check a few things before recovery of password:

To activate question, try typing the login: follow-up of your user name and password.

For Ganymede number:

1.] error on the section of logging of the server Ganymede while accessing the credentials of Ganymede.

2.] was there any problems reachbility during this time?

3.] all services came fine?

4.] should focus on debugs following:

debugging Ganymede

Debug aaa authentication

I'm not sure if this can be replicated, but yes love to help out if possible.
