Cisco Firewall :: ASA5585 WCCP-GRE Redirection To Websense Times Out?

Dec 9, 2012

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.

Cisco Firewall :: WCCP Redirection On ASA 5520

Jul 17, 2011

I currently have WCCP redirection setup on my ASA 5520 to redirect to an ironport on ip address The ASA inside ip is 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 But I can't get traffic to redirect.

Cisco Firewall :: ASA 5520 VPN Users With WCCP Redirection To IronPort

Apr 11, 2012

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.

Cisco Application :: 3945 - WCCP Redirection For WAAS On Same Platform Using Different Service Group?

Nov 9, 2011

if a Cisco router or switch can handle wccp redirection enabled for both waas and some other web content filtering appliance using a different service group?
seems like the priority value would come into play determining which service group gets handled first?
we currently do WCCP for WaaS on our 3945s.
I am going to advocate to my customer that we separate this out for CPU load issues, config complexity issues, IOS issues, etc... but the question is going to come up - "can we do WCCP for different applications on our Catalyst 3750 core switch, or our 3945 WAN routers?"

Cisco Switching/Routing :: 7206VXR - WCCP Redirection Of Non-directly Connected Subnets

Jul 18, 2012

I have a Cisco 7206VXR running 12.4(24)T3 IOS. It is configured with WCCPv2 using L2 mask redirection. I am using service groups and associated extended ACLs to select which subnets I want to redirect port 80 traffic from.
It is working fine for the subnet
int gi0/2
ip wccp 10 redirect in
ip address
... however, there is OSPF running between the router and a Mikrotik device directly connected to this interface. The gateway addresses for all the client subnets are on the Mikrotik. Traffic from other subnets, e.g., come in on this interface and I want to redirect those too. But it appears that the redirection doesn't work for those subnets (I don't see any hits on the relevant ACL for any subnet except
It seems like the router only wants to redirect traffic for subnets that it has an IP address in itself. Admittedly, all of the example configs i've found on are for redirecting traffic from directly connected subnets but I can't find anything that denies thie possibility of redirecting any traffic that comes in on a given interface.
The question is, is this how WCCPv2 redirection works? i.e., the router must have an IP address in the subnet to be redirected?

Cisco Firewall :: How To Configure 6 To 4 Manual Tunnel On ASA5585

Jul 6, 2012

I have ASA5585 Firewall between my WAN Cloud and LAN Network. I plan to configure Layer 3 Vlan Interfaces inside FW and it would be Layer 3 gateway for some of Subnets. Layer 3 VLAN Interfaces are planned to be dual stack containing both IPv4 and IPv6 Address stack.
I plan to configure 6 to 4 Tunnel with my Hub Site where we have native Ipv6 awareness. One tunnel end point would be ASA and the other endpoint would be Hub site WAN Router/L3 Switch. So IPv6 traffic hitting to vlan interfaces on ASA  would be policy checked and routed over tunnel interface to Hub Site.
6to4 Tunnel manual tunnel configuration on ASA. I have configured such tunnel on L3 Switch or Router with following config.
Int tunnel xyz
  ipv6 address  <ipv6 address>
  ipv6 enable
  tunnel source <loopback address of my L3 Switch>
  tunnel destination <loopback address of my hus site L3 Switch/Router>
  tunnel mode ipv6ip
I need to implement something similar in ASA. How can I do that?

Cisco Firewall :: ASA5585 Active And Shared Interface Design

Aug 18, 2011

use of a pair of ASA 5585's in active/active mode with a shared outside interface.Last time I did this was with FWSM, there was a restriction where all contexts that share an outside interface have to be in the same failover group.Does this apply also to the ASA? My thought is that it will, but I am unable to find that in any documentation.

Cisco Firewall :: Cut Over ASA5585 Global PAT Address Without Connection Drops?

We're currently PATing everything from a particular subnet to the IP of an outside interface using our ASA5585 (dynamic PAT). We're experiencing pool exhaustion and therefore need to expand the global IP range. Any way of cutting over to the new range without dropping existing connections? For clarity, the current interface address is x.x.x.37/22 and the new PAT pool is x.x.x.114-6/22.

Cisco Firewall :: ASA5585 State Link Supported Over MPLS?

Jun 29, 2011

Running ASA5585’s in active/standby across a local campus MPLS network. Supported design, leading practice etc. Specifically our design is that two ASA5585 are configured as active/standby through a local campus MPLS network over 10gig links through ASR9k etc. The ASA’s are providing inter-vrf routing capability only with p2p l2vpn circuits configured for each logical interface between the ASA over MPLS etc.The failover link is via a direct fibre and the state link will be through a p2p l2vpn (option for direct fibre also)Is this a supported design to begin with?

Cisco Firewall :: ASA5585 Interfaces Not Connecting Palo Alto Failed Or Shutdown

Jun 9, 2012

We have pair of ASA5585 (ver 8.4(4) with IPS module configured with Active/Standby failover. There are total 09 interfaces are connecting to different zones in the firewall and out of which three(3) interfaces are connecting to Palo Alto 2nd layer firewall. When we test the failover whatever interfaces not connecting Palo Alto failed or shutdown, ASA triggers the failover to other unit, however the Palo Alto is not detecting this failover and it still keeps its previous Active Palo Alto to pass traffic, thereby failing passing traffic on Active firewall through Standby Palo Alto firewall.
But when there's a interface failed or shutdonw on the interfaces where PaloAlto also connected, then once the ASA failover triggers and the same time Palo Alto also trigger its  failover then both new active firewall and Palo Alto sending traffic through firewall.However we  we cant all the interfaces of ASA also to connect Palo Alto and let the Palo Alto to inspect all the interfaces, but we need our ASA to work in a situation where any of the interfaces failed, the failover to work smooth the pass the traffic via either Palo Alto device.I just need to know is there anything tricky that we can configure on our ASA in this failover senario, or to confirm if there's no any workable solution to this situation.
I have attached the senario that I explained above. Just to emphasis the issue again, if any interface of Gig0/0, Gig0/4 or Gig0/5 failed on active firewall, ASA switching to standby firewall and act as Active, but Palo Alto still remains his Active state and the new Active ASA is not passing traffic via standby PA as its not detecting any of its interfaces as failed or unreachable..?

Cisco AAA / Identity / Nac :: Webauth Url Redirection Fail With Firewall Between Host And Switch

Feb 27, 2013

Web auth redirect URL gets dropped if stateful firewall is between webauth host and switch management interface.  Aaron at Cisco live london kinda hinted about maybe Cisco working on this ?  We can't disable stateful inspection. Is there any other solutions or workarounds ?
"Although this approach introduces additional hops in the return path from the switch to the host, it produces negligible load on the default router and intervening infrastructure since only the WebAuth traffic from the switch to the host follows this path. In campus designs that do not use SVIs on the data VLAN,6 a default route is typically already configured. In this case, no additional configuration is required to support WebAuth.

However, problems may arise in the case in which traffic to the default router is bridged through a stateful firewall. The original SYN packet in the TCP handshake is consumed by the access switch, so the first packet that the firewall sees is the SYN-ACK packet from the access switch. Stateful firewalls typically drop SYN-ACK packets if they have not seen the original SYN packet.In this case, you will need to turn off stateful inspection for ports 80 and 443 on the firewall."

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 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 Barracuda IP   All PCs in the 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

I suspect my issue is that the ASA is generating a Router Identifier of which is my inside network and the barracuda cannot communicate with it.  how I can get this working ?

Is this supposed to work transparently or am I missing a config?
