Cisco Firewall :: Pix 515 Configuration Required

Oct 18, 2011

I am very confused on how I setup a Pix 515 that I just got to route traffic out a cable modem. First, let me give you a little details on my current network setup and what I am trying to accomplish with this Pix 515. Currently all my users go out the proxy for any internet access, however I have certain users that need to go out the cable modem instead of the proxy server. Below is an example of the current IP setup of a user A:The cable modem that we currently have has DHCP so I would need the external PIX address to accept a DHCP address. I also don't really understand what else I need to setup so if I have say four users hitting the cable modem through the pix how do I direct their web traffic to the correct computer (NAT ?),I will be plugging the PIX into a cisco switch that all ports are in VLAN 48 so hopefully a static internal address on the pix of 10.24.48.254 will keep me from having to do any routes since all traffic will be originating from the 10.24.48.0 network.

Cisco Firewall :: ASA 5505 Dual WAN Settings Required

Feb 27, 2012

I have a 5505 configured with a active/standby dual wan setup using the sla tracked connection settings. Is there a way to configure the ASA to stay on the backup connection after activating? We had a situation where the main T1 was bouncing, so the backup connection was being activated and deactivated very often. The problem is that there is an app being used that does not allow users to reconnect to dropped connections immediately, so every time the asa switches wan connections it causes a significant disruption.I should note that I already set monitor options frequency to 240 seconds. I could set it higher, but then we have a longer delay when the main connection dies.

Cisco Firewall :: How Many Watts Required - ASA 5505 Power Consumption

Jan 20, 2013

My ASA 5505 getting pretty hot after a while and so I used a wattmeter to find out what´s happening.
 
260 watts is quite a lot if the device is running in idle mode and has no active device attached nor any config has been installed.
 
What's your experience of the ASA 5505 power consumption ?

Cisco Firewall :: ASA 5520 SSL VPN LDAP Authentication Configuration Required

Oct 16, 2012

I've gotten to the point where I can test against active directory and get in, also I can get AD groups from my server on the ASA. My problem, I can't connect in via my AnyConnect client on my Android. I immediately get a "log in failed" and I know I'm using the right username/pass. Doing a little troubleshooting, I have attached my AnyConnect debug log and the results of the "debug ldap 255" command on the ASA. Also, I've used ldp.exe to determine I can connect in with the username/password combo I'm using.Combing through the AnyConnect logs I see a few instances of "global error unexpected" but no Google searches have brought up anything useful.

Cisco Firewall :: ASA 5505 - SIP Configuration Without NAT

Oct 15, 2012

I am new to using the ASA 5505 appliance.  I have successfully configured it so far, but the one piece that eludes me and I can't find an example of configuring SIP with internal (DMZ security level 50)) VoIP phones to an external call manager (external, security level 0) without using NAT.  I have an internal V LAN to an internal B2 router (and management) on eth0/7, an external V LAN (/30 to an external B1 border router) and five different DMZ V LAN on ports eth0/1-eth0/5.
 
On the external router, the internal interface going to ASA5505 are separate sub-interfaces for each V LAN in the DMZ and one /30 V LAN to connect between the router and ASA.  I am using vrf forwarding on the DMZ sub interfaces with IPSEC/GRE tunnels to keep the routing tables separate.  I cannot have the different DMZ V LAN's communicate with each other (that's why I am using vrf).
 
Everything works, all my tunnels are up, I  can ping to the external sites from the DMZ V LAN's and pass data, but I am stymied by setting up VoIP.  When I used the wizard (big mistake) it setup up all sorts of certificates and NAT (since I really didn't know what I was doing at this point).
 
Any hints on configuring VoIP from phones in the DMZ V LAN's to an external call manager?
 
I would include the current config, but I have to hand transcribe it since we don't allow usb connectivity.  I might be able to provide it a little later.  i am using ASDM 6.4 and ASA IOS 8..4

Cisco Firewall :: ASA 5505 Backup ISP Configuration

Jun 13, 2011

I'm having problems configuring an asa 8.2(1) with a backup isp.  I followed the asdm instructions in this document: [URL]
 
I have my backup interface configured as DHCP and the static routes set. Pinging the gateway and other external IP address from the backup interfaces works normally. I have also tried configuring the backup interface as a static address but got the same results.
 
When removing the primary wan link, all traffic stops. When I ping a external DNS, I get these errors in the log: portmap translation creation failed for udp src inside: 192.168.13.23 dst backup:208.67.222.222_type 8, code0)
 
I though this type of error is related to a NAT problem, not sure where to look though.

Cisco Firewall :: QoS Policing Configuration On An ASA 5505?

Jun 10, 2013

I'm working on QoS policing configuration on an ASA 5505.The ASA is situated behind a cable modem which provides an SLA of 3.2Mbps out.I've configured a QOS policy to place VoIP and other essential traffic (RDP/Citrix/PCoIP) into a priority queue, whilst policing default class to 3.2Mbps to police out to the cable modem.I can see on the outside interface graphs that this is rating the output traffic down to 3.2Mbps as expected, but noticing at certain points of high output traffic drops down to 1.6Mbps.  I can't see anything obvious in syslog or any other areas to look, so looking for any pointers as to why the speed is suddenly dropping down.  Likewise if I rate the output to 2Mbps, it will suddenly drop down to 1Mbps at high output rates.the ASA is running on 8.0(5) and I enclose a copy of the sample QoS config below and attached a sanitized run config, as well as screenshot taken of the outside interface Bit Rates plus service-policy.

Cisco Firewall :: ASA 5505 Configuration For AT&T Microcell

Mar 2, 2011

We got an AT&T Microcell a couple of weeks ago, hooked it up to our CISCO PIX 506 firewall and it worked "out of the box". We then upgraded to a CISCO ASA 5505 when the Pix died last week. Got the ASA 5505 up and running pretty much "out of the box", only having to setup our IP addresses (inside & outside). The 5505 is NOT configured as DHCP since I have an existing server in house that assigns IP addresses and I don't want to mess around with changing everything. However the Microcell wasn't working on the new 5505. Found in the Microcell manual that the following had to be "open":

123/UDP (NTP)
443/TCP (HTTPS)
4500/UDP (IPSec NAT Traversal)
500/UDP (IPSec phase 1 prior to NAT detection)
 
From the 5505 Config Guide, I found that I needed to ENABLE NAT-T, so I did this with the following commands:
crypto isakmp enable outside
crypto isakmp nat-traversal 3600
 
Using the "Packet Tracer" in ASDM, I found that ALL 4 types of packets were allowed going from the ATT Microcell (192.168.10.52 on my INSIDE network) to the OUTSIDE interface (66.xxx.xx.xx). However, all 4 types of packets FAILED when the Packet Trace was reversed (Source = 66.xxx.xx.xx, Destination 192.168.10.52).
 
The Packet Trace pointed to the "implicit rule" to DENY IP traffic. So, using the ASDM, I setup Access Lists for the above 4 ports/protocols, both on the INSIDE & OUTSIDE interface, both INCOMING & OUTGOING. Still, no success and the Packet Trace in ASDM still pointed to the IMPLICIT DENY rule on either the INSIDE or OUTSIDE interface, depending on which Interface I was initiating the Packet Trace. I tried setting the Access Rules for "Any" IP Address (not just the public IP or the Microcell IP) on both the Source/Destination for all 4 ports. What is even more confounding is that when setting up these access lists to PERMIT traffic, my internal network  Internet traffic stopped for ALL workstations on my network. Phone started ringing no more than a minute after I applied any PERMIT rule. By deleting the rule just installed, traffic started flowing again.
 
My number one questin is why don't the access lists work and why does settin up a "permit rule" kill my internet traffic?
 
I'm not a network expert and sprinkle holy water on our network every morning. I cringe when I have to make changes (like putting in a new firewall) because I don't know all the inner workings, parameters and setups done over the years by predecessors. I need to get the ATT Microcell up and running and figure the experience will be beneficial as our next step is to setup a VPN.

i have 2 ASA 5505 running 8.3(1) and ASDM 6.3(1).
 
the first unit is currently working, and i now wish to configure the second unit as standby. im configuring through the ASDM GUI. Started the HA Wizard, choose Active/Standby configuration and enter the IP of the peer device. checks come back all ok. On the LAN link configuration page (step 3of6) Interface is pre selected as VLAN99, I give it a logical name as iface_fail, and enter 10.0.0.1 as primary address and 10.0.0.2 as standby, subnet as 255.255.255.248, and select port Ethernet0/5
 
Note that if i click on the buttons next to the IP fields, i get IP addresses of remote hosts!.

Cisco Firewall :: ASA 5505 - Backup ISP Link Configuration?

Jan 28, 2013

I'm working on setting up a backup link for our ASA 5505 and I've followed these directions:  [URL]
 
The backup ISP gives us a dynamic address, however, when I enable the backup ISP's interface on the ASA, my vpn tunnels drop. As soon as I disable the backup interface, the tunnels come back up. I'm attempting to configure this across one of these tunnels, so obviously this is an issue, as is the fact that other people need the tunnels as well. I'm not sure what I did to make this happen, but I've been over the config many times and can't see anything different from the instructions in the link above.
 
I thought it might be trying to route traffic across the backup interface, but my primary interface is tracked and has SLA running on it, so I would assume it wouldn't roll over onto the backup interface.

Cisco Firewall :: ASA 5505 - DMZ Configuration With Base License

May 24, 2011

My ASA 5505 base license allows for three VLANs, the third one can only initiate traffic to one other VLAN (as specified by no forward interface vlan <number> on the third VLAN). This doesn't mean it can't "access" the other VLAN, it just can't initiate traffic to it. A lot of people get that wrong.Let's say you've got three VLANs, one is OUTSIDE, two is DMZ, and three is INSIDE. On the second VLAN would I enter the no forward interface as vlan 3, then set the name via the nameif command and everything will work just fine. The DMZ will not be able to initiate traffic to the INSIDE, but will to the outside, and assuming you have your ACLs and NAT set up properly, it will be able to respond to traffic from the INSIDE.
 
Would that be best practice or would I enter the "no forward" interface as in VLAN 1, thus is being able to respond to traffic from the outside as opposed to the inside.
 
I had a DMZ set up but since there was an intrusion into my network, I am building it again.

Cisco Firewall :: Random ASA 5505 Configuration Reloads?

Oct 16, 2011

I've been trying to track down intermitent problems with one of our branch office ASA5505's .The way we have been tracking it is primarily through ping/icmp connectivity. Occasionily our tracking software will report that is stops responding to ping requests then in almost less than a minute it will start replying again. I'm allowing icmp to that interface and it is internal. Examing the logs it almost looks like the config is being reloaded but I've never seen this kinda of log before so I'm not sure if it is just sending it's config to a host or actually reloading its config.
