Cisco Firewall :: FWSM V 4.1.3 Forwarding Packets To Sender MAC Address
Feb 26, 2011Does the FWSM v 4.1.3 is capable to forward return packets to the MAC address that sent them to it first?

View 6 RepliesI happen to noticed the FWSM was dropping packets at about 387 packets every 5 minutes. My outside FWSM is WAN facing and has a 1gig link (35% utilized) my inside facing has about 100 downstream switches to the closets. I do not see my 6509's back plane is being over utilized and my understanding of the FWSM show be go for 5 gig so it isn't oversubscribe. Why i am seeing packets dropped?

I have 2 FWSM running on 2 Cat6500 chassis, they work as a Active/Stanby group. Firewall mode is transparent. [code] HA is running well, but I can not ping the standby IP (10.98.1.248). So what could be the problem?

I am trying to correctly configure our ASA 5520 and our Mitel Border Gateway in our DMZ. In the documentation for the Mitel border gateway it wants me to set up 2 external IP's on my ASA one to allow 443 traffice into the MBG, and another for 443 traffic that needs to be forwarded to port 4443 for the MGB in the DMZ. My problem is I don't know how to do this. the MBG only has one IP, and I need to have 2 different URL's mapped to two different external IP's both externally using port 443, and one of them forwarding to 4443 on the DMZ interface.

When debugging ip packets (debug ip packet 52), I found a whole lot of these:
May 4 22:42:14: pak 5007BF54 consumed in input feature , packet consumed, MCI Check(55), rtype 0, forus FALSE, sendself FALSE, mtu 0May 4 22:42:14: pak 5008C488 consumed in input feature , packet consumed, MCI Check(55), rtype 0, forus FALSE, sendself FALSE, mtu 0May 4 22:42:14: pak 46A3E474 consumed in input feature , packet consumed, MCI Check(55), rtype 0, forus FALSE, sendself FALSE, mtu 0
May 4 22:42:14: pak 5007624C consumed in input feature , packet consumed, MCI Check(55), rtype 0, forus FALSE, sendself FALSE, mtu 0
The problem with this is, today's date is the 5 May. The clock on the device shows the right time, but these debugs aren't.
We have a 3750x 24s acting as a root switch for about 10 other 3750x's. Everything else seems fine, but the device stopped forwarding packets to the applied static route. [code]
View 3 Replies View RelatedFrom everything I read it seems like DFC is for forwarding packets. When I hear packets I think of layer3. If my 6500s are just being used as a big layer2 only switch do I need a DFC? I am being told the 6500 looks at the layer 2 frame and the layer 3 patch header information before forwarding the frame. How true is this?
View 1 Replies View RelatedI have a requirement to monitor downstream data feed from a remote site and feed it to multiple destination devices for recording. The source data will be fed into a port on a Cisco 2960G switch then, using the monitor function, be forwarded to multiple interfaces. This works fine for normal Etherent II traffic. We tried a test using a device that generates IEEE 802.3 Raw packets ('type' field is used as a 'length' field) but found that while the traffic appeared to be accepted by the input port with no errors it was not forwarded to the destination ports, even when using the monitor function. I did try the 'encapsulation replicate' feature with no luck. It does not forward these packets even if I set all the ports into a common VLAN and let the switch just perform a normal switch function (non monitor).
if it is possible to get the IEEE 802.3 raw packets to pass through the switch and if it is, how to or what I need to do to make it work?

View 1 Replies View RelatedI have a problem with x4648-rj45V+E module, which is not forwarding frames/packets in my 4507E switch. I have done the diagnostic and the module test is passed. When i try to ping from one PC to another in the flat network, icmp is not forwarding. Even i cannot see the mac addresses in the mac address-table. But i can ping to my management port in the sup module?
View 12 Replies View RelatedWe have 2 FWSM modules in each 6500 switches. 1st module is having 04 firewall vlan groups with 18 vlan interfaces in a single context firewall. All are working fine with no issues. Recently we create one more vlan on MFSC and add into the same firewall module. However newly created vlan inside the FW is not able to communicate with outside and also outside users not able to reach newly created subnet. But within the firewall zones (other interfaces) it can communicate. Once we did packet capture we noticed that its hitting firewall outside interface only and when we ping we got TTL expired error. we have default routes to outside and there's no any route inside as new segment is within the firewall (no any hop).
I guess there's no limitation on number of vlans that we can assign on one firewall eventhough there is a limitation for number of vlan-group which is 16 max (but we are within that limit).
I have some Ethernet-connected cameras that all have the same Ethernet MAC address FF:FF:FF:0A:0A:0A. They were originally designed to directly connect to a Windows PC, but they can also connect through a simple unmanaged switch.A Catalyst 3560 switch won't forward packets to or from anything with that MAC address, at least not by default. Is there a way to convince the switch to do so?
It was my hope to replace the dedicated connections we have for these cameras with a separate VLAN for each camera, and switch them through our existing switch network. Given that all of the cameras use the same MAC address, putting them on the same network is out of the question, but different VLANs, where the only two devices on each VLAN were the camera and the PC that uses it, would be fine.
The switches run IOS 12.2(55) SE through SE3. I learned the camera MAC address from the PC's ARP table while the camera software runs; it turns out the cameras don't have a full IP stack either and don't even do ICMP.
I have a RV042 using (for now), just the single WAN interface. I am trying to forward all packets to port 9000 from the WAN to a single IP address on the network. I've set up both forwarding rules under Setup -> Forwarding and under the Firewall -> Access Rules.I cannot connect to my device from the outside world, however. Is there something I'm missing?

We recently deployed a FWSM on our 6503-e boxes (w/ sup720). NAT is working (PAT) but the issue I am seeing is private traffic from remote sites is not being allowed through the FW. I was able to get the remote site to ping the FWSM itself (inside address), but no hosts behind it. Maybe an ACL issue? Also when I turn off NAT on the remote end, I can than access everything (We are NATng on both ends). Im a routing guy by nature so I will defer this to the security guys out there.

We have a pair of 6500s with Sup720 running 12.2(33)SXI3. Each has an ACE-20 (s/w A2(2.0)) and FWSM (s/w v3.2(15)). We have reached a limit on the number of rules we can configure on the FWSM, and have determined that we shall upgrade to 4.1(5), with ASDM to 6.2(2)F. A question has been raised regarding the s/w on the ACE-20 modules. Do we need to upgrade them as well?

1. what wrong with the new interfces i created?
2. whats the logic of auto adding a rule to "all" interfaces , the rules are incoming rules specific to interfaces or groups , why add the to the rule to "all" intefaces?.
We would like to decommission our FWSMs and upgrade to the ASA 5555Xs. This leads me to ask the following: What would be the most efficient way of doing this without any interruption to production? How to successfully accomplish this?

I think I got a strange behavior on a context of my WS-SVC-FWM-1 (on a Catalyst 6509 running IOS 12.2(18)SXF17a) that is running FWSM Firewall Version 4.1(3). This context sends these log messages every ten minutes:
Jul 17 2011 23:31:16: %FWSM-6-302010: 0 in use, 0 most used
Jul 17 2011 23:31:17: %FWSM-6-302010: 2245 in use, 107133 most used
[code]...
If I issue the "show conn" three seconds later the log message, the output I got is: FWSM# sh conn 1041 in use, 107133 most used
In another context on the same FWSM the log message sent every ten minutes is just this one:
Jul 17 2011 23:31:17: %FWSM-6-302010: 1358 in use, 72503 most used
Jul 17 2011 23:41:22: %FWSM-6-302010: 1590 in use, 72503 most used
In this case there is no the log message where the "in use" field and "most used" field are 0 (zero). why does the context send the message with the "in use" field and "most used" field 0 (zero).
I have attached a drawing of our network. We have two 6509's connected to two Cisco 2811 (onsite) that the ISP owns. I am trying to get one side up and running before I worry about redundancy and so forth. For this reason I have set all the HSRP priorities to 110 on the left 6509. I have HSRP running between the ISP routers and V LAN 101 of the 6509's. This works as I can ping yahoo and Google just fine from the 6509 switch. I can't get from my laptop connected to V LAN 23 to the internet.
It doesn't even attempt to NAT as there are no translations. I have public address assigned by my ISP configured between the ISP routers and my 6509 on V LAN 101. I then have the public address assigned to V LAN 100. I configured V LAN 100 on the switch and V LAN 100 on the FWSM with the IP address in the drawing. I have my NAT statements and route in my FWSM according to the drawing as well. On the switch, I have a default route to X.X.12.19 which is the VIP between the ISP routers. I can reach anything on the inside of my network, including the old network addresses from V LAN 23.
1. Is it best to do NAT at the FWSM or should I do it on the MSFC connected to the ISP routers?
2. If I have to configure NAT at the FWSM, does this requires me to extend the public network down to the FWSM?
3. I'll take any examples you may have as I am stuck.
