How can I make it so traffic can enter one router and exit the other?
The two routers have HSRP to provide fail over between the two, and BGP is setup so one BGP route goes ESHDSL-ADSL and the other ADSL-ESHDSL

if I do #sh arp in the terminal with this router I see a rogue entry thus:
Internet 192.168.0.4 0 Incomplete ARPA
My whole LAN operates on 172.16.x.x/16, there are no 192.168.x.x devices connected. In the past I've had 192.x.x.x devices running but for a long time and the router has been restarted since then. I've tried several clear commands in the terminal but this entry is stuck there and I've also seen it in a wireshark scroll on a pc when monitoring the routers' adsl traffic - it shows up an an SNMP entry and I do use SNMP on my router, but that data goes to a 172.16.x.x. machine. How can I clean this entry out?

All of the servers will have public IP addresses.Now - the network guy at the new DC has confirmed that a simpler two switch configuration will work.

We recently purchased a Cisco 2921 router to be our edge device for a small satellite office (24 users). In addition, to the router we purchased a vwic3-2mft-t1/e1 module. Now the surprise, we ordered a bonded T1, I thought we were getting frame-relay circuits from Verizon, but someone ordered a 3M IMA circuit. I am new to configuring serial connections, and had planned out a frame-relay configuration. With that said, I have the following questions:
1. Can I setup a working serial connection to Verizon using the installed ATM circuit and the 2921 and vwic3-2mft-t1/e1 card I have? If not, what do I need in conjunction with the 2921?
2. With the frame-relay configuration, I enable controllers, configured the MFR interface and sub-interface, and serials. How much different is setting up serial ATM connections?
I am having a public IP address and it is not configured on any of the router interface on my Cisco router. I am having 3 internal networks. Is there any way to PAT all these 3 internal networks to this public IP?

I have a requirement to NAT a spare address on the same subnet range as one of the firewall interface - however, because this is not allocated to a physical interface, there is no mac entry in the arp cache. the other end of the link from the firewall is connected to a router which has no idea how to reach this "virtual address" - again because there is no entry in the arp cache I have tried to put a static arp entry into the firewall but this doesn't appear to work either. Should I be using a mac address form a physical interface or can I create a dummy mac for this - If the router can't see the ip address, then users will not be able to target this address - so that the firewall can NAT to the real outside address.I have tried routes to null0 on the router and static arp entries on both devices but the user just times when trying to connect to 10.2.7.11 (nat to 10.2.32.11)

View 2 Replies View RelatedI have a wap200 with a static ipaddress e.g. 192.168.249.205/24 (it is for management and is in vlan 1). Firmware of the wap is 2.0.4.0. No gw and no dns. (they are not necessary) I export the config . I have a second wap200 and import the config.bin to the new wap. ThenI like to change the static address and the name of the new wap, but - and this is the problem - it asks me to fill out the dns (the address for primary dns cannot be 0 and 255), but I absolutely don't want that because there is no dns or gw (management only). And if I fill it out I cannot go the the internet with the wap.
So I also have some other wap200 where I could import the config.bin and change the static ip without giving a dns (firmware 2.0.1.0). can I go back to a previous firmware (Europe) and where can I find it. Looked for it, but seeing only the last one 2.0.4.0 etsi.Or is there another method to skip the dns with a static ipaddress?

View 2 Replies View RelatedIn my environment, VPN users are connecting to corparate network via ASA 5540 and using 3.5.1, 4.8, 5.0 (32 bit) and 5.0(64 bit) VPN clients.After they have built VPN connection, they use program that generates traffic to a bradcast address (x.x.x.255) inside corparate network.
There is no problem with users who are using 3.5.1 and 5.0(64 bit), but 4.8 and 5.0 (32 bit) vpn clients can not add ARP entry to Windows machines ARP table. If i add ARP entry for x.x.x.255 on VPN interface, they can work.
I am having peculiar issue in my setup. I recently replaced my ASA 5505 (8.2.1) with ASA 5510 (8.4.3). Everything works fine for a while suddenly I see some of the servers will not be reachable from the LAN all the servers gateway is my switch. If I check on my Dell switch the particular server's arp entry on the connected port is same as ASA physicall MAC. If im reverting to 5505 ASA everything goes smooth without any issue.

We're replacing our older catalyst switches with new SG300 family switches and have a Microsoft NLB cluster for some services that run in multicast balancer mode.
We currently do L3 routing to the network with the cluster and have the following IOS configuration line in the specific switch to let users on other subnets to access the services.
arp 10.20.1.226 03bf.0a14.01e2 ARPA
How do we replicate this using the SG300 series in L3 mode? Whenever I try to add a manual ARP entry I get an error message that says that the MAC address is not a valid unicast address?
through asa webvpn we need to provide our user remote destkop access; we would not use static rdp:// bookmarks for this accomplishmet as this would grow too much management effort with bookmarks updating. Our strategy would be to give users the "url entry" bar where they can input the resource name (example: "pc-flavio.mydomain") so the management effort is outplaced to the guys who manage the dns server. This stated, we noticed that most end-users would get in troubles because of the default-ing "url-protocol" is http://, so they don't change it to the correct rdp:// from the drop-down list and don't have the java-rdp applet started. There is a chance to admin the default protocol for URL Entry Functions? Our setup is asa 5510 ver 9.1, act/stb failover.
View 2 Replies View RelatedI have a client in a workgroup environment. They are a small company with perhaps twenty systems. Their infrastructure consists of a Dell Switch, a Cisco ASA-5505 which hands out the DHCP and a router. And that's that.They have been using an external IP as their DNS Server to get out to the Web. However, they now want to add an internal Linux-based DNS server.In looking through the ASA-5505 today I noticed a field for DNS enteries. Is this where the IP for this new internal DNS Server (in the secondary DNS field) would go?If so, would it be necessary to reboot the ASA-5505 for this change to take effect?

We have a pair of 6509's with duplicate ACL lists & entries.
1 = Version 12.2(33)SXI4a
2 = Version 12.2(18)SXF15a
I wanted to remove some logging that was on an entry on one of our extended ACL's. On 1 this worked fine with the no 400
400 <acl rule without log>
However on 2 it lets me carry out the no 400 command but when i go to add the 400 <acl rule without log> i get the error % Duplicate sequence number.sure enough when i perform the 'Show access-lists <Name>' it is still there!
I have tried the following:
Adding a duplicate ACL entry before it (399) without log and i still get hits on line 400Adding and removing the duplicate created line 399 (without logging) with no issues.Adding and removing a dupliacte ACL (without Logging) after (line 401) with no issues
It looks like it is just this line it seems to think it has removed but hasn't?!
I understand an option is to duplicate the ACL in a text editor remove line, delete the ACL and put the edit back in .....however i wondered if this is something known (bug).
I would like to capture packets which are going through an IPSEC tunnel. The packets originate in the appliance (syslog) and are sent to the remote via a VPN. I can see the encapsulated packets going out to the peer and I can see the ISAKMP packets to and from the peer. Because the packets originate within the appliance, they do not appear on any interface to be captured.
Is there some way to capture these packets before they are encapsulated?I attempted to capture packets on the asa-dataplane, but they are in a format that I cannot decode, and I cannot put a filter on the capture.

Does PBR with deny ACL entries on a 3750 are still punted to the CPU? I found this article: URL
High CPU Due to Policy Based RoutingPolicy Based Routing (PBR) implementation in Cisco Catalyst 3750 switches has some limitations. If these restrictions are not followed, it can cause high CPU utilization. You can enable PBR on a routed port or an SVI. The switch does not support route-map deny statements for PBR. Multicast traffic is not policy-routed. PBR applies only to unicast traffic. Do not match ACLs that permit packets destined for a local address. PBR forwards these packets, which can cause ping or Telnet failure or route protocol flapping.
Do not match ACLs with deny ACEs. Packets that match a deny ACE are sent to the CPU, which can cause high CPU utilization.
In order to use PBR, you must first enable the routing template with the sdm prefer routing global configuration command. PBR is not supported with the VLAN or default template
I checked the latest config guide, and those same guidelines are still listed. If that limitation is still there, are those packets switched at the process level (ip_input) or the interrupt level?
