Cisco Firewall :: ASA 5512 WCCP Configuration With Web Filter
Oct 31, 2012
I am currently trying to enable WCCP between a Cisco ASA 5512 firewall and Barraccuda Webfilter 410 Vx applicance. The ASA firewall is running IOS version 8.6(1)2 and the Barracuda is funning firemware 6.0.0.013. Both the ASA and Barracuda are in the same network and can ping eachother. The ASA has several interfaces, outside, inside, data and dmz. The PCs and barracuda appliance are behind the data interface. ASA data IP 172.16.18.1 Barracuda IP 172.16.18.40 All PCs in the 172.16.18.0/24 subnet use the ASA as the default gateway and should have web requests redirected to the Barracuda.
Below are the respecive bits of my ASA config
interface GigabitEthernet0/0
description Management
speed 1000
[Code].....
I suspect my issue is that the ASA is generating a Router Identifier of 172.21.20.1 which is my inside network and the barracuda cannot communicate with it. how I can get this working ?

I have a customer who needs a 5512-X set up with two ports on the "Outside" interface and act like a switch on the outside. This is very easy to do with the way the ASA 5505 works just by creating vlans and treating the ports as members of the vlan.

configuration of a Catalyst 3750X and Barracuda Web Filter using WCCP protocol.
We used various WCCP protocol settings, unable set to redirect traffic to the Web Filter.
This is the current configuration of 3750X:
ip routing
ip wccp 94 redirect-list 194 group-list 50
ip wccp 95 redirect-list 195 group-list 50

I recently configured WCCP with a Sophos Web Filter on my network it works good but the problem I am having is I have two 5520s so I am directing the device to look at 2 different IP addresses and since the devices are in an Active/Passive failover. The problem is because the second device is in a passive failover it is not responding which is throwing connection errors to my Sophos device. I know you can have a single management connection for the ASA's but is there a way to have a single IP for the ASAs for the WCCP?

I have a WCCP Configuration on a Catalyst 3750G and a IronPort Webappliance. I have configured this situation many times before with cisco asa and ironport wsa, but with a switch, this is my first time.
VLAN 147 is a transportation vlan between the cisco switch and a hp coreswitch with the clients and servers behind the hp coreswitch.
VLAN 147 IP Address of the Catalyst is 172.30.47.1
IP of the IronPort Appliance is 172.30.47.10
IP of the HP Coreswitch is 172.30.47.2
Plan is to redirect the webtraffic coming from clients and servers from the 10.0.0.0/8 net behind the hp switch to the ironport wsa. In have configured these settings.
ip wccp web-cache group-list 15 password 7 091D1C5Aip wccp 80 redirect-list 16 group-list 15 password 7 14464058
interface GigabitEthernet1/0/22 description IRONPORT P1 BUWOG switchport access vlan 147 switchport mode access

I'm looking to make a possible configuration for a customer. They need a device to provide :- firewalling- bandwidth limiting based on protocols, IP, users- web content filtering- good reporting to see which device/users are consuming most of the bandwidth.I used to use cisco ASA as firewall but it's a while I last installed on and I'm nt uptodate which current state.So I thought of using an ASA 5512-X but I'd like to know if it comply with all the requirements .Most important being the reporting and bandwidth limiting capability. It would be great to have some configuration example regarding bandwidth management.

I have a windows 2003 server and an ASA 5512
I'm trying to use SSLVPN and it was all working, and I don't believe any configs on either box have been changed.
On Friday people were connecting, but now I get a message "Login Error" in the browser. In the ASDM home 'latest ADSM Syslog Messsages' I get "AAA authentication server not accessible", followed by two messsages AAA Marking LDAP server in group as FAILED AAA Marking LDAP server in group as ACTIVE
When I go to configuration --> Remote Access VPN --> AAA/Local Users AAA server groups and click on my RADIUS server and click Test, it takes a while and says ERROR: AD agent Server not responding: No error
If I stop my IAS server on my Windows box i get the same error but much more quickly.
I have a sonciwall set up doing the same thing, and RADIUS seems to work happily, so I don't think it's the server config...

My collegue and I have been trying to figure out why we are unable to get this ASA to NAT Overload correctly. I'm sure it is something stupid, and the config may have gotten a little dirty as we tried to change options and make it work. FYI, we can ssh from the WAN into the device to configure it. It is communicating externally, but it isn't natting.
ASA Version 8.6(1)2

I am having soem difficulty getting documentation and setup procedures for the new ASA 5512-X (or X models in general) firewalls.I know the IPS sensor is a software-based one, but I'm not sure how much different the setup in than with a 5510 and IPS module.
Also, is the IOS upgrade procedure different?

I am configuring a brand new pair of ASA 5512s running 8.6(1). Traditionally we hae been using the Management port as the dedicated failover link, but that seems to not be possible on the 5512s.
ASA (config-if)# no management-only ERROR: It is not allowed to make changes to this option for management interface on this platform.
I have not been able to find anything in the official documentation mentioning this restriction.

I installed a new ASA 5512-X over the weekend for a client. Their backup ISP connection is DHCP based. I need to use the 'dhcp client route track' command on the interface, but it is not available. However according the all the documentation I am looking at and even the ASDM says it should be available.
This is the version of ASA and ASDM they are running:
Cisco Adaptive Security Appliance Software Version 8.6(1)1
Device Manager Version 6.6(1)
I did upgrade to the latest ASA software, so has this command been removed? If I do a '?' in the interface, there isn't a 'dchp' option.

I'm porting our configuration from a Pix 515 firewall to an ASA 5512x. What's vexing me right now is with the deprecation of the "static" command, I can't quite figure out the best way to Identity NAT my inside sub nets (multiple) to the DMZ sub net
So on the pix I have my identiy NATs as an example:
static (inside,dmz) <IntSubA> <IntSubA> netmask 255.255.255.0
static (inside,dmz) <IntSubB> <IntSubB> netmask 255.255.255.0
static (inside,dmz) <IntSubC> <IntSubC> netmask 255.255.255.0
Cisco's migration guide seems to do them one object at a time, which I guess is straightforward enough to do:
object network SubA
subnet <IntSubA> 255.255.255.0
[code]...
I'm thinking that there must be an easier way (aka less lines) to implement this for all the sub nets I want to Identity NAT to the DMZ.
1) Can I do this creating objects using a sub net with a net mask of 255.255.0.0 - one object to cover multiple internal sub nets?
2) Can I do this using object groups and trim this down to: (assuming I have to commands right)
Object-group network Inside_Subs
network-object <IntSubA> 255.255.255.0
network-object <intSubB> 255.255.255.0
network-object <intsubC> 255.255.255.0
nat (inside,dmz) source static Inside_Subs Inside_Subs no-proxy-ARP route-enabled. What would be the best way to translate my Identity NATs?

I currently have WCCP redirection setup on my ASA 5520 to redirect to an ironport on ip address 10.11.1.10. The ASA inside ip is 10.11.1.1 and the ironport is setup for transparent redirection to that IP. This all works well and the Service Identifier i'm using for WCCP is 95.I am now creating another WCCP group because on my ironport I have 4 interfaces so I wanted to use them for our admin network. So I created an ACL on the ASA for our admin traffic and I want to redirect that using Service Identifier 94 to the ip on the ironport of 10.11.1.22. But I can't get traffic to redirect.

I have the following topology, WCCP is configurated on ASA, inside interface, lan users and websense machine are located on the same VLAN of my catalyst 3750G?I want to filter traffic on port 80 (www) to the users on the LAN side debug on the ASA show me that comunication between that device and Websense is OK, there is Here_I_Am and I_See_You packets
WCCP-PKT:D00: Sending I_See_You packet to WEBSENSE_PROXY w/ rcv_id 0000015B
WCCP-PKT:D00: Received valid Here_I_Am packet from WEBSENSE_PROXY w/rcv_id 0000015B
WCCP-PKT:D00: Sending I_See_You packet to WEBSENSE_PROXY w/ rcv_id 0000015C
WCCP-PKT:D00: Received valid Here_I_Am packet from WEBSENSE_PROXY w/rcv_id 0000015C
WCCP-PKT:D00: Sending I_See_You packet to WEBSENSE_PROXY w/ rcv_id 0000015D
From show WCCP i saw that WCCP engine and ASA were detected

If you look at the data sheet for the 5512-X the High Availability section states "Not Supported; ActiveActive or ActiveStandby" while the ASA 5515-X states "ActiveActive or ActiveStandby". What does "Not Supported" mean for the ASA 5512-X? Does this mean HA does not work, or that I need to purchase an additional license to use the HA feature?

I have a Cisco 5512 x Firewall connected with Cisco Layer 3 switch 3750.I have two different WAN connections, one for Data and one for voice. Cisco Layer 3 switch is configured with 2 different VLAN's one for data & other is Voice Vlan. Switch is providing DHCP to computers and IP phones. Voice Pool 192.168.10.0/24 Vlan10 and Data pool 192.168.20.0/24 Vlan20.I need to route my data & voice traffic separately. Cisco ASA is connected with two different ISP's. So, how can I do this configuration so that Voice and Data traffic will route separately.

From what I can find the ASA does not support policy routing.
I have two VLANS that need to go to the same destination but different routes. Anyway to accomplish this on the ASA?

I have a problem with random host's geting the wrong source address on a ASA 5512-X 8.6(1). Right now there is a host, 192.168.25.108, showing up with 6.6.6.6 (fake) on whatsmyip.org, should be 5.5.5.5 like the rest of 192.168.25.0/24. In the xlate tabel I cant find anything wrong. Same yesterday with two host, that are using the right NAT address today.
nat (any,outside) dynamic interface. (5.5.5.5)
object network H-192.168.25.10

Just doing some basic testing before we replace our ancient PIX 515E with a new 5512. I have a mini lab set up following the diagram below, although I am unable to telnet through to the mail server's netcat listener on port 25 TCP. I can ping all the way outbound from 192.168.101.1 to 10.0.0.2, and the 10.0.0.2 machine shows it is translated properly to 200.225.117.1.
NAT and access rules are as follows:
object network mail
host 192.168.101.1
description Mail relay
access-list inbound extended permit ip any host 200.225.117.1
[code]....
EDIT: Somehow the new global access rule is involved. When adding a permit any any in there I can get to the mail server no problem. When I remove it but leave in my permit ip any any on the outside interface, I am denied?

Is the 5512 able to be field upgraded to a 5515 and so on through 5555? I.E. Can I add ram and other hardware to make the boxes more powerful as my requirements increase? I was hoping this would have been a new feature with the ngen firewalls.

I've been asked to deploy an ASA in Transparent Mode because of concerns of putting another layer 3 hop between PE and CE routers running BGP.
Is there some problem with allowing BGP to flow freely through an ASA the is also terminating site to site and remote access vpn tunnels?
I just don't see the need for Transparent Mode here and you cannot have a standard DMZ setup with Transparent Mode: you have to use bridge groups to provide for multiple interfaces on the ASA and then have an external router route between those bridge groups.
what I'm missing here as to why Transparent Mode is needed (not needed)
ASA is 5512

I have a ASA5585 running 8.4 that is redirecting Internet http to a websense server via GRE.The integration is working fine, except when a user PC sends a large packet (~1500 bytes).With WCCP/GRE headers, the user packet is too large to be transmitted to websense, so the ASA fragments the packet in two and transmits both to websense.
A sniffer trace confirms that both fragments reach the websense server, but the TCP packet is never acknowledged.User-side TCP retransmits the large packet three times over 15 seconds, and eventually retransmits fine with smaller packets. The 15 second delay is of course not acceptable.Users and Websense server are both on the Inside interface.
We are considering imposing browser proxy to websense (which works fine), but would prefer not, considering the increasing diversity of devices.

What the support for WCCP on a FWSM running 4.0(7) is like, if there is any at all ?
I've read that the earliest PIX release that supports WCCP was 7.2(1) but I'm not sure how FWSM 4.0(7) aligns with the PIX versions.The only doc's i can find refrencing WCCP on a 6500 with FWSM is in the 6500 12.2 IOS guide.

I have a IOS firewall on a 2921 router, zone-based config. The remote and main sites have Cisco WAAS , running 4.4.1 software. I am using WCCP redirection on the WAAS/router combination. If I leave it off the firewall passes SSH correctly to the devices on the other side of the firewall. If I enable WCCP the SSH connections fail. The SSH to the router itself is fine, I am not using the self zone for router protection. I had seen a few posts on WAAS but the only one mentioning a config statement in the firewall was on 4.0 WAAS and the command is no longer on the IOS firewall. Is this supposed to work transparently or am I missing a config?

I have a 5520 ASA using wccp redirection to our IronPorts on the inside and everything works great for inside users. What I'm trying to do is get VPN users off split tunneling and to filter their traffic through the IronPorts as well but I can't figure out how. When they connect they seem to bypass the Ironport completely.
