Cisco Firewall :: Twice NAT Not Working With 5510

Aug 22, 2012

Our NOC is trying to configure a site to site tunnel to one of our customers. The tunnel is up and operational, however we can't get our NAT rules to match what we want.
 
We are running ASA version 8.4(3)
 
The traffic is sourced from 172.16.1.50 (inside1) and destined to192.168.2.9 (outside), the nat configuration is posted below:
 
NOC-ASA5510-01# show run nat

object network obj_any
nat (inside1,outside) dynamic interface dns
object network servers-noc
nat (inside1,outside) static 192.168.1.68
 
Here is the output from the show nat detailed:

Cisco Firewall :: ASA 5510 NAT Doesn't Appear To Be Working

Mar 8, 2012

I've got an ASA 5510 running 8.4.I have a host on an inside interface, with a static NAT configured on the ASA. The inbound/return half of the NAT doesn't appear to be working. [code] I run a ping from the host (192.168.100.98) to something on the outside (1.2.3.4)Running captures, I can see the outbound ping leaving, having been NATed OK. I can see the reply coming back in to the outside interface with the correct IP address, but I never get the final NATed packet appear on the inside interface. The packet just disappears inside the ASA.

Cisco Firewall :: SSH Stops Working To ASA 5510?

Feb 5, 2013

I find are steps to turn on SSH access.  I have quite a few customers with ASA5510's installed.  SSH is set up and working fine on every one.  After a period of time, you are no longer able to SSH into the firewall.  Using Putty, it just sits there on a blank screen without giving a "denied access" message or a login prompt.  Rebooting the firewall will solve the issue and SSH access works again.  Today, I had a customer with and active/standby configuration where I had to reboot both of them to be able to log in.  Most of my customers are on 8.2.software as most don't want to reconfigure for the new NAT, etc. 
 
I'm sure others have seen this before since it appears to be occuring on almost every ASA that I have access to.  Is there any fix to eliminate this or is there something that can be run from the ASDM that will grant SSH access again without just doing a reboot?

Cisco Firewall :: ASA 5510 - HA No More Working After Upgrade To 8.4.1(11)

Jun 2, 2011

we recently upgraded our ASA 5510 active/standby cluster from ASA Version 8.3.2 to 8.4.1(11). Unfortunately the standby ASA is now crashing a few seconds after the configuration was synchronized from the active ASA.
 
Also completely disabling HA, bringing the default config to standby ASA again and activating HA afterwards did not work. Also tried through the Wizard provided by ASDM to be sure to have no errors with requirements.
 
How to solve this without doing a downgrade back to 8.3.2. ?

Cisco Firewall :: ASA 5510 - Vpn Tunnel Not Working From One End

May 9, 2013

I have an ASA 5510 and I am building a site-to-site vpn tunnel, peer on the other end is a sonicwall. I can initiate the tunnel from my end, but when he tries from his end it fails on phase 2 with this error in the logs:
 
"Rejecting IPSec tunnel: no matching crypto map entry for remote proxy"
 
Obviously our crypto map's don't match, i have it restricted to specific ports on my end and he had it wide open on his end, but said he is not sure how to restrict it down to specific ports. My question is why would I be able to bring the tunnel up on my end if the crypto map's don't match and he can't bring it up?

Cisco Firewall :: ASA-5510 - SIP ACL Traffic Not Working

Jun 11, 2013

I have an ASA with an outside ACL that is configured to allow 208.84.248.95 SIP/5060 to 1x.x.x.46.  I show no hits.  I added an ACL to do a packet capture, it sees the packet coming into the ASA but not going to the Serv Prov interface.  I see hits on the vuong ACL but not the production acl_out ACL..  What is up?
 
NOTE:ACL_out is the ACL we use to allow outside traffic to enter our network. 
FW1(config)# sh access-list | i 1.x.x.46
access-list acl_out line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=0) 0xc09a9387  (*NO HITS)
access-list acl_out line 658 extended permit udp host 208.84.248.95 host 1x.x.x.46 eq sip (hitcnt=0) 0x0f327179  (NO HITS)
[code]...

It was tested and verified from the inside network to make sure the server is listening on that port. Below we created an ACL to allow all IP from another test PC to the Server IP 1x.x.x.46.  We did a telnet to port 5060 and it showed hits but not on the acl_out ACL.
 
ccess-list vuong line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=0) 0x2759fa92
FW1(config)# q
FW1# capture capture1 access-list vuong interface outside
[code]...
 
Below we applied the same ACL to the ServProv interface to see if traffic was going where it was supposed to .  By trying to telnet to the 1x.x.x46 IP from 63.x.x.140 IP.  Looking below, no traffic appeared on the capture2.
 
FW1# capture capture2 access-list vuong interface ServProv
FW1# sh capture capture2
0 packet captured
0 packet shown
[code]...
 
Capture 1 above shows the last 3 incoming messages initiated from 63.x.x.140 to the 1x.x.x.46! Vuong ACL belows shows 3 more hits.....nothing on the acl_out ACL???
 
FW1# sh access-list vuong
access-list vuong; 1 elements; name hash: 0x29df3e90
access-list vuong line 1 extended permit ip host 63.x.x.140 host 1x.x.x.46 (hitcnt=6) 0x2759fa92

Cisco Firewall :: ASA 5510 - Static NAT For Outside Access Not Working?

Sep 19, 2011

I've got an ASA 5510 that has been working like a charm for some time now. Until now we've not had to nat any resources to the outside. I created network objects for an internal host and an external host. The internal host has to respond to requests on tcp/2001.
 
The internal host has no problem accessing the internet, but when I attempt to access the internal host from the outside, I get the following:
 
4    Sep 20 2011    16:20:33        fw_outside_ip    62678    outside_host    2001    Deny tcp src outside:outside_host_ip/62678 dst inside_host:inside_host_ip/2001 by access-group "outside_access_in" [0x0, 0x0]
 
When I try to use the packet tracer to simulate the outside traffic, I get the following
 
5    Sep 20 2011    16:17:41        inside_host    2001            Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:outside_host/1065 dst inside_int:inside_host/2001 denied due to NAT reverse path failure
 
I've got over my NAT statement and access rule and can't find anything wrong with either.
 
Here are the pertinent NAT and access rule...
 
static (inside_int,outside) tcp interface 2001 inside_host 2001 netmask 255.255.255.255
 
access-list outside_access_in extended permit tcp host outside_host host inside_host eq 2001

Cisco Firewall :: ASA 5510 Object-Groups Not Working

May 9, 2012

I have an ASA 5510 and have just started using object-groups which are super handy in theory, but not working in reality. I have a service object-group with a mix of tcp, icmp, and udp ports. Let's call it Sample_Port_Group. I'm trying to apply it to my dmz_access_in ACL. Here's the line giving me problems:
 
access-list dmz_access_in extended permit object-group Sample_Port_Group 192.168.1.1 any
 
The asa throws up an error between 192.168.1.1 and any. When I put up a ? after Sample_Port_Group, it gives me the option of putting in an IP address, any, etc. When I put in a ? after 192.168.1.1, it only gives me the option of putting in an IP address.URL

Those posts gave me the impression my line was possible, especially the "access-list outsideacl extended permit object-group myaclog interface inside any" line, which is at the end of the 2nd article linked.

Cisco Firewall :: 5510 Exchange Active Sync Stops Working

May 8, 2012

I know that I've run into this before but I can't remember the fix.  I have a 5510.  The 3 interfaces involved are INSIDE, OUTSIDE, and GUEST. Corporate users are allowed to put their iPhones on the Guest network, but the problem is that their Exchange ActiveSync stops working.  It is tied to the external DNS name of the OWA server (we'll say webmail.abc.com).  So the users are funneled out one public IP on the OUTSIDE interface and are trying to communicate with the outside of the OWA server, which is NATed to another public IP on the same outside interface.  What do I need to do on the ASA to allow users on the guest network (behind the GUEST interface) to access the mail server using its public IP (behind the INSIDE interface)

Cisco VPN :: Verify NAT On ASA 5510 Working?

Aug 16, 2011

I'm working on setting up a site-to-site VPN connection that requires us to NAT an internal address.  Typically, this would be no big deal, but for some reason, it's not working for us.  The remote site is reporting that they are seeing the original IP address and not the mapped address coming across.  I've monitored the connection and base on our ASA logs, I too see the un-mapped address. 
 
Is there a quick and easy way of verifying that NAT is working?  Logs, etc.?
 
Unfortunately I don't currently have the remote side's configuration, as they are an external business, but I can provide ours: [code]
 
Based on the above, it sounds as if our configs aren't jibing, which I would think could be caused by the NAT configuration not working, right?  I mean if the VPN applicance on the remote end is expecting a NAT-ed address of 12.131.67.247 and they are receiving 12.10.127.108, that could cause this issue, couldn't it?

Cisco VPN :: VPN Not Working After Adding Subinterface - ASA 5510

Nov 19, 2012

Currently I want to add a second lan (vlan) in a customers network. The new network will be for a wireless infrastructure.There is also VPN Configured on the ASA - One with L2TP for Windows Clients and an IPsec for Cisco Clients.Former we only had one outside (Eth0/0) and one inside interface (Eth0/1) on the ASA.Now I want to use the Eth0/2 with subinterfaces, so that we will be flexible for future, when deploying more vlans.But now, when i turn the first subinterface Eth0/2.2 to no-shut the VPN Connections does not work any more.Bulding up the VPN connection works, but it seems that the traffic is not tunneled. (I checked this, because tracert to an internal adress goes to the internet)Below there is my config, i don't know whats wrong. I think split-tunnel is configured correctly (because it works when i delete eth0/2.2) TREV is the network of this location.Company1,2,3 are remote locations.

Cisco VPN :: Asa 5510 Remote Apps Not Working After Upgrade From 8.0 To 8.4

Nov 1, 2011

We have a 5510 ASA that was running 8.0 and were using it for clientless VPN access. Through this, we published bookmarks that linked to an internal Microsoft 2008R2 RemoteApps server, which users logged on to and then launched RemoteApps (basically being RDP sessions to apps on the server).All worked fine until we upgraded to 8.4 over the weekend and we now can't launch the RemoteApps. We can still login through the ASA, still click a bookmark to take us to the RemoteApps server's webpage, still then authenticate against the domain fine and still see the published apps. The problem now is when we launch the apps we get "this computer can't connect to the remote computer" messages and the app fails to launch. Nothing has changed on the RemoteApp server side, only the upgrade to 8.4.

But now when I try to connect with my Android I get this error: "Clientless (browser) SSL VPN access is not allowed".

Problem is, this week someone sent a larger email 20+mb to dozens of recipeints and the outside interface was hitting 10mb, which is not what I would have expected with this rule in place, so I'm questioning the configuration. We know it was email because I disabled the server that receices our outbound mail to apply a signature and the traffic dropped immediately.

Cisco Firewall :: ASA 5510 / Multiple VLANs Behind Single Firewall Segment?

Feb 5, 2012

I need to create a firewalled segment that not only separates hosts from general population, but also from each other.  The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible.  1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
 
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9 

This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).

Cisco VPN :: ASA 5510 - Group-Lock Not Working With Web VPN And RADIUS Authentication

May 16, 2013

I'm on an ASA 5510 running 8.2(5)41. I have clientless WebVPN configured to authenticate against an RSA RADIUS server, which has users assigned to RADIUS Class attribute 25 to match the group-lock values assigned to each ASA group-policy. This of course is to ensure users can only access the login page's drop-down VPN profiles they are assigned to by the RADIUS server. I have two other ASA 5510s (same code level) using the same RADIUS server with group-lock enabled but for IPSec remote access VPN's, and the group-lock feature works fine.

WebVPN, however, is authenticating any user to any VPN profile without regard to the RADIUS Class attribute 25 they are assigned. If I configure the VPN profiles to authenticate locally and assign group-lock to individual ASA user accounts, group-lock works. As soon as I point it back to the RADIUS server, group-lock does nothing. From the 'debug aaa' below for user 'corpvpnstp', you can see the RADIUS server sends back the attribute 25 values of "ou=stp.Client;" and "ou=stp.ClientDRC;" for this user. The ASA profile this user has attempted to connect to is "EMS-Admin", which should get denied by the ASA. Instead, the ASA successfully authenticates the user.
