Cisco Switching/Routing :: 2600 / Destination IP Address Redirection

Jul 9, 2012

I have a Cisco 2600.  I would like to know how to redirect traffic going to a certain IP address three hops away to an IP address on a locally connected segment. 
 
Ex.  Packet leaves a device with source IP of 10.10.10.10 and destination of 20.20,20.20   When the packet hits the router (10.10.10.1) I want the router to redirect the destination of 20.20.20.20 to 30.30.30.30 (locally connected segment).
 
The router has two physical interfaces.I am thinking along the lines of creating a VLAN with an ip of 30.30.30.1 and then doing a NAT translation from 20.20.20.20 to 30.30.30.30.

Cisco Switching/Routing :: 861 - External IP Redirection (Port 80)

Mar 5, 2013

I have a little problem with a redirection. When I type my external ip, I am directly connected to my Cisco 861 ( through port 80 (HTTP))

Even if I do a factory default, I always have the same problem. I try to make another redirection on another internal ip , but always same problem...

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 192.168.1.0/24....
 
int gi0/2
ip wccp 10 redirect in
ip address 192.168.1.99 255.255.255.0
  
... 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. 192.168.2.0/24, 192.168.3.0/24 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 192.168.1.0/24).
 
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 cisco.com 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 :: ASA 5505 Port Redirection On Same Public Address?

May 26, 2012

We have 2 TS (Terminal Servers) and have configured the 1st RDP using my public address (say 8.8.8.8) on port 3389. it is working very well of course. However I need setup my 2nd TS but will use port 7777 on the same public address which is not working.I am using ASDM 6.3 and firmware 8.3.1.Is this a limitation for this IOS?

Cisco Switching/Routing :: Destination Host Unreachable 2400

Jun 8, 2012

My company has a Cisco IAD 2400 which is handling our phones and the internet (from Service Provider). We are adding a second router, a Cisco 1921, to our network,I think I have everything set up correctly. One department is using the 192.168.2.0/27 subnet. I can ping each computer within that subnet. Also, within this subnet, I can ping the router interface at 192.168.2.1. I can ping 192.168.1.2 successfully as well. This is the interface on the 1921 that goes to the 2400. However, if I try to ping 192.168.1.1 (interface on 2400), I get "Reply From 192.168.1.236: Destination Host Unreachable" I get the same thing if I ping 8.8.8.8.Within the 1921, I can ping 192.168.1.1 and 74.125.224.72 (random google ip) successfully.

Cisco Switching/Routing :: 3750 - Tagging Traffic By IP Source And Destination?

Dec 2, 2012

I want to know if there is way to tag traffic with DCSP tags without having to do all the other requirments of QOS setup.  All i want to do is just tag traffic at different DCSP values via source and destination IPs.  We do not have a need to be priortizing traffic on out internal switches.  We just want to tag the traffic so our MPLS provider can distinguish the different types of traffic.
 
Our environments is primarily 3750s in all offices.

Cisco Switching/Routing :: 6500 VSS Architecture With Two Equal Cost Paths To A Destination?

Apr 29, 2012

I have a query on how the 6500s running in VSS mode would route the traffic over an OSPF environment where it has leant about two equal cost paths, but one via the 2nd chassis.Proposed setup - 2 6509s running in VSS. Switch-1 in VSS has a layer 3 connection (via a LES circuit) to one of a pair of Nexus 7Ks at another office. Switch-2 in the VSS has another layer 3 connection (via LES by another provider) to the other N7K at the other office. The L3 connections would use /30 ranges and allow each Nexus to form an ospf neighbour relationship with the VSS. We want to keep both offices environments separate so although we do have L2 circuits we're using these to provide L3 connectivity between sites & exchange routing info via them using ospf.

Each Nexus will advertise all the directly connected networks it knows about to the 6509s running in VSS. Thus I couldn't figure out if for example we have users/servers behind our VSS 6509s, these would need to go via their default gateway to get to a network located off the LAN, the default gw ip in VSS setup exisits on the control plane on switch-1 (in normal operation). Then to get to a network that is located off the Nexuses at the other site it would have 2 equal cost paths to it, however one of these paths would be via the VSL link and off the switch-2 chassis. I wasn't therefore sure if we'd actually ever see any transmit traffic via the 2nd L3 connection because I have a funny feeling that I've read the VSS always choses the local chassis egress rather than going via the VSL to use another port...
 
All of the above is theorectical at the moment as currently both circuits are connected to a single Nexus/6509 chassis however for improved resilence I want to move one of the circuits to be physically attached to the other Nexus & 6509 chasis at each site but I wasn't then sure how the traffic flows would be affected.

Cisco Switching/Routing :: NAT On 12.1 IOS 2600

Nov 10, 2011

- I have an older router 2600 running 12.1(4) IOS.
- There are a few clients connected to it via the frame relay connection.
- There is an IP that clients access 192.168.1.10 for example
- We need to do a NAT for this IP for one specific client only like "ip nat inside source static 192.168.1.10 1.1.1.1"
- However if I do that, that will effect other clients too
- On the interface for this client I'll be using "ip nat outside"
- Is there a way to accomplish this without effecting other customers?

Cisco Switching/Routing :: 2600 / 3550 - InterVLan Routing

Dec 2, 2011

I've been working with these two Cisco devices in my home off and on for several months now but I just can't take it anymore, I'm about to throw them away and go back to Linksys router.
 
I have a Cisco 2600 Router with only one Ethernet card in it so I have to trunk from my 3550 Switch to that device.  I'd like to have my ISP and all users plug into switch and all trunk back to the router's sub interfaces. Currently, I have started over...again, and am unable to simply get the router and switch to ping each other if I put sub-interfaces on the router.  See my configs:
 
2600 ROUTER:
Router#sho run
Building configuration...
Current configuration : 555 bytes
[code]......

3550 SWITCH:
Switch#sho run
Building configuration...
Current configuration : 2302 bytes
!
version 12.2
[code]..........
 
Port F0/24 is in VLAN 1, as are all ports but Port F0/1 which is my desktop PC. I mocked it up in Packet Tracer and it works just fine.  This is just a simple setup and I'm making sure I can ping between switch and router before I move to each next step.

Cisco WAN :: Why Is Destination An RFC1918 Address

Mar 13, 2012

Here is a snippet from "show ip cache flow", from a border router of our network; [code] To clarify, Gi0/3 faces our customers, Fa1/0 faces a transit provider. These results have come from configuring "ip flow egress" on Fa1/0, facing the transit provider. 1.2.3.4 is a static IP we have assigned a customer. I know this customer has a firewall terminating this connection so I want to understand the cache flow results on this route. Why is the destination address an RFC1918 address? Is it possible that the customers firewall is trying to connect to these addresses, the flow gets as far as this border router, and drops? I assume that to be false, and only successfully initiated flows are recorded?
 
Also, looking at those figures it's IP protocol 0x11 which is UDP (17) and source port 62023 to destination port 161. 161 is SNMP? Without asking the customer what they are doing I suppose I can never know at that level, but I'm really more interested in why these flows are showing at all, when 192.168.1.0/24 isn't in this routers FIB?

Cisco VPN :: ASA 5510 - NAT Destination Address Through VPN?

Feb 25, 2012

I am trying to perform destination NAT through a VPN tunnel.my scenario traffic coming from 172.29.11.135 needs to connect to address 192.168.1.1 from the source device traffic will have a source IP address of 172.29.11.135 destination will be 172.30.14.1 traffic will hit the asa 5510 and the traffic source will stay as 172.29.11.135 but the destination needs to change to 192.168.1.1.
 
I have tried the different types of NAT but been unsucessful with all. My VPN tunnel will connect if the destination address does not change (NAT Exemption used). This scenario is even possible on Cisco devices. I have seen discussion that NAT the source address but not the destination address.
 
example config
access-list FROM_INTERNET extended permit esp any any
access-list FROM_INTERNET extended permit ah any any
access-list FROM_INTERNET extended permit gre any any
 access-list FROM_INSIDE extended permit ip host 172.29.11.135 host 172.30.14.1
access-list VPN-TUNNEL extended permit ip host 172.29.11.135 host 192.168.1.1
 
**I have left other config statements off as the NAT config used previous has not worked and the VPN tunnel does build when using NAT exempt.

**All ACL have been applied in the inbound direction on the respective interfaces. Two static routes have been applied to the FW directing inside traffic inbound and all unknown traffic outbound. I have not defined a specific static roule for the VPN traffic allowing the default static to perform that function.

Cisco Security :: ASA 8.4.1 Destination Address NAT?

Jul 15, 2012

i have a situation where i have a deployed asa5505 running 8.4.1.The client has an existing mail server that is located on their lan and has Port Nat's configured for the normal mail ports,  25,110,993,587 etc.
 
This works fine for mail inbound and for any user popping mail off the server externally or visiting the webmail interface from outside the network.However when users inside the LAN try to connect through the ASA back inbound to the IP on the External Interface of the ASA they are unable to do so.
 
One solution i came up with is Split DNS.   and well this works it rely's on the users not changing their dns servers.I was wondering if it's possible to do some sort of NAT that rewrites traffic destined for the above ports on the external IP to the Internal LAN Ip instead.

Cisco Switching/Routing :: ERSPAN Source On Nexus 5548 And Destination On Catalyst 6500

Aug 9, 2012

I'm trying to get ERSPAN working with an ERSPAN source on a Nexus 5548 and the ERSPAN destination on a Catalyst 6500.
 
The configuration on the Nexus is as follows:
 
[...]
interface loopback0
ip address 192.168.2.133/32

[Code].....
 
If I do a netdr capture I can see ERSPAN traffic sourced from the Nexus reaching the C6500, but there doesn't appear to be anything sent out the ERSPAN destination inerface (Gi4/6) and there's nothing being received by the probe connected to that interface. I know the traffic seen with netdr is definitely the ERSPAN traffic sourced from the Nexus as I've changed the TTL and DSCP values within the monitor session on the Nexus and can see those changes reflected on the C6500 netdr capture. The attached is a screen grab of the show netdr capture started with debug netdr capture soure-ip-address 192.168.2.133.
 
When I look at the interface I see it shown as up/down (monitoring), but no output or counters clocking up. If I run a local SPAN session on the C6500 it works fine.
 
I've tried changing the destination IP address from that assigned to the C6500 Loopback interface to an IP address assigned to a physical interface, but that still doens't work.
 
The hardware in the C6500 is WS-SUP720-BASE Hw version 3.2 with WS-F6K-PFC3B Hw version 2.4. The IOS version is 12.2(33)SXI6.

Cisco Switching/Routing :: 877W - Multiple Static Routes / Same Destination Dialer0 And Vlan1?

Jun 10, 2013

Is there any way to have my Cisco 877W Router alter from using one static route to another static route when another router on the network is reporting destination host unreachable?
 
Router 1 (192.168.2.253)
Dialer0 -> ppoe to internet
Vlan1 -> local 192.168.2.0/24
 Router 2 (192.168.2.254)
Dialer0 -> ppoe to managed VPN (172.16.28.1)
Vlan1 -> local 192.168.2.0/24
 
Router 2 is connected to another network through a managed VPN and that network also has internet access. I want to be able to have two routes to the internet on Router 2. And when Router 1 internet goes down packets get routed through the VPN instead.
 
I currently have on Router 2
 
ip route 0.0.0.0 0.0.0.0 192.168.2.253
ip route 10.0.0.0 255.255.255.0 Dialer0
ip route 0.0.0.0 0.0.0.0 172.16.28.5 250
 
Which does nothing when Router 1 has its Dialer0 interface shutdown, or goes offline completely.I suspect I could reverse the setup and have everything routed through the VPN by default and then if / when Dialer0 interface goes down it would switch to using Router 2, but if the problem is in the remote network and interface Dialer0 stays up, it would probably do the same thing... nothing.All devices mentioned are Cisco 877W routers with ADSL and a bunch of fast ethernet interfaces.

Cisco Switching/Routing :: 6513 Monitor Session Source Vlan And Lost Packets At Destination

Feb 20, 2012

We have 2 6513 switches with SUP720/PFC3A and various POE modules and a 6748-GE-TX  facing our servers.  Additionally, we have a 4Gbps portchannel trunk interconnecting the switches.    We have approximately 300 Nortel IP 1140e phones in use between the two switches.For the purpose of call recording, we've attempted to mirror the voice vlan using various approaches and have been met with limited success.  We mirrored the VLAN using tx, rx, and both.  When using both we appear to get duplicate packets at the destination interface.We seem to lose packets completely going in one direction or another for a given call. Packets are lost before they get to the destination interface?

Cisco Switching/Routing :: 2600 Access To Internet Using NAT?

Jul 30, 2012

We have recently leased an internet connection in our office which comes from the service provider as radio link and BW is 2M. I have clients more than 60 that will share the connection and access internet. I have configured a Cisco 2600 router as below:

Building configuration...
 Current configuration : 988 bytes
!
version 12.2
no service single-slot-reload-enable
no service timestamps debug uptime
no service timestamps log uptime

[code].....
 
So far I have read regard NAT it degrades performance as it need to translate every data packet comes from the source and goes to internet. So a question comes in my mind is there any other way how I can share this connection among users with private ip address? Or NAT is the only method to share internet connection among users with private ip addresses?

Cisco Switching/Routing :: 2600 - Cannot Ping Outside Router

Oct 25, 2012

I am connecting a 2600 router to an ISP. Interface 0/0 is connected to the ISP using DHCP. Interface 0/1 is connected to the inside providing DHCP services to the inside. At least it should only be providing DHCP services to the inside. I also have a public static IP that is NAT to a private static IP. Everything is working except the computer on the static IP. From the router I am able to ping inside and out from each interface. I am able to ping both interfaces of the router from the computer on the static IP but I cannot ping outside the router. If I do a debug all I see a reject for the gateway of the static IP but it has “mobile IP” in the text string. Not sure what mobile IP is relating to. Networks are as follows:

0/0 DHCP 10.X.X.X
0/1 192x.x.x
Static 75.X.X.X  
no ip dhcp use vrf connected
ip dhcp excluded-address 192.X.X.1

Cisco Switching/Routing :: 2600 - Source IP Set To Public When Packet Received

Mar 27, 2012

We have Cisco IP phones behind a 2600 series router:Most of the time when the PBX receives a packet from the phone, the source IP of the packet is set to the public IP of the router (1.2.3.4) as expected. However, once in a while, we get packets (at the PBX) with the source IP set to the private IP of the phone (10.0.0.12).The router is configured by our provider, and they can't give us any explanation for this behaviour. Is it safe to assume that PAT is not configured properly at the router?

Cisco Switching/Routing :: 2600 DHCP From Service Provider Not Working

Feb 7, 2013

So I have  a 2600 that I have configured three sub interfaces on. FA0.0.1 is set for DHCP and supports VLAN 1. FA 0/0.2 for Voice, FA 0/0.3 for Data. I have this router interface plugged into FA 0/24 on my 3550 and the 3550 is configured as a dot1Q trunk (I have attached configs for RTR and SW).I have most ports configured as access VLAN 1 which is where i have my ISP connection plugged FA0/1 on the 3550. When I connect the service provider link FA0/0.1 never picks up an address. If I take my internal DHCP server and connect it to FA0/1 of the 3550 it snags an address almost immediately.In my mind this validates that my config is fine. I also took the same cable from the service provider cable modem and connected it to my laptop and the laptop is pulling DHCP.
