Cisco Switching/Routing :: C3640-JS-M - How To Configure NAT
Aug 2, 2012
I've been trying to configure a connection which requires NAT translation but my devices are too old and seems that the configurations I tried doesn't work or I don't know how to implement it properly.Firstly, I will introduce my router to you, it is a Cisco C3640-JS-M Version 12.2(1), so I found many ways to solve my problem, but none of them are supported by it.
To continue,the connection I am trying to configure is the following one:
10.1.1.0/24(My LAN) --- (My ROUTER) --- 192.168.9.1/25 <-----> 192.168.9.126/25 --- (OTHER ROUTER) --- 172.22.1.0/24 (Their LAN)
So one host from 172.22.1.0/24 needs to connect to a server in my LAN (10.1.1.20) but they can´t use the real IP and we need to configure a NAT rule to translate traffic from them to 192.168.6.10 to 10.1.1.20, but only for this connection (there are other "WAN" interfaces.
These are my failed attempts:
interface FastEthernet0/0.302
ip nat outside
ip nat inside source static 10.1.1.20 192.168.9.10
PROBLEM: Works for this connection, but other connections are affected and no one can reach 10.1.1.20 apart from LAN and incoming traffic to F0/0.302
[code]....
But as I said before, some configurations are not supported by my device.

For an assignment in a class I am taking I created a simple network using GNS3 and set up static routing. Everything works fine, I can ping all of the hosts. One of the questions I am supposed to fill out is what happens when I use the "show ip route" and "show ip protocols" commands. When I use "show ip route" I get what seems to be the correct output. However when I use the "show ip protocols" command nothing happens. No output, no error, no nothing. It just goes right back to the prompt. This happens exactly the same on both routers in my network. incase it matters the router is c3640.
PS. would the output be non-existent because I have not set up any ip protocols. In a similar assignment I set up rip and when I used "show ip protocols" i did get what appeared to be the correct output. However I didn't write it down and when I put in the command again about an hour later after I took a break I also did not get an output until I re-entered the rip related commands.

upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

In our datacenter we have a 3750 stack with IP base image. I have enabled PBR and reloaded the switch. Show sdm prefer says i am using default template. The reason i want to use PBR is that we have 2 firewalls on the same work and want to be able to have granular control over which gateway out of the network they use but still be able to access all internal resouces accross wan and locally.
Created access list to identify traffic:
access-list 10 permit 10.2.3.59 (test workstation on vlan 3)
Created policy:
route-map TestASA permit 10
match ip address 10
set ip next-hop 10.2.0.3
Assigned policy to the user vlan3:
ip policy route-map TestASA
Results:It changed the default gateway to the above gateway but i could not access any resources on any other vlan, could not access resouces accross wan.

The layer 2 switches are connected to layer 3 Switch via trunks, and routing between layer 2 switch ports with configured SVI's on 3550. All working fine. Now I'm trying to configure routing between 2800 and 3550, I tried connecting both Straight Throught and Crossover cables to the 2800 Fa0/0 and Fa0/1 ports as well as the switchports on 3550
No switchport commands are configured however, the lights do not go on for both straight through or crossover cables. I tried connecting 1750 routers but same result. My goal is to have all the VLANS routed to the internet with configuring NAT translation the router.

If I have an ASA 5520 with an INSIDE interface, a DMZ interface and a WAN interface what would be the best way to configure NAT? If I configure nat-control and a nat (inside) 1 0.0.0.0 0.0.0.0 this will configure everything to be NAT'd when passing from the INSIDE interface out.My question is what about the devices I want to access in the DMZ from the inside for management etc? I'm guessing the ASA isn't smart enough to realise you're accessing hosts in it's DMZ interface so do you have to configure a nat 0 rule for every subnet within the DMZ you want to access or is there an easier way to do it? It's worth noting that the same devices will be accessing the OUTSIDE network and the DMZ network from the INSIDE network.

I have a customer who is on thr 192.168.254.x subnet and is using a Cisco 881 as their gateway.
They wish to create a second VLAN for the 192.168.253.x subnet.
The Cisco has Dialer0 configured for an ADSL connection.
I have partly configured the router but need some info regarding router a device on the 192.168.253.x subnet to the internet.
configure routing to the internet on the new VLAN and assist in setting up a DHCP server on that vlan. I have attached a copy of the current config.

I notice that NAT is not possible Cisco Catalyst 4500e series. Is there any other ways to configure NAT? Currently we have 2x Catalyst 6509 and we're migrating to the 4510e and there's NAT in the 6509s. I was thinking of re-using the 6509s and connect to the 2 new 4510e in a meshed trunking layout with MST (Layer 2) and OSPF/EIGRP (Layer 3) protocols turned on.

I believe I have the steps done at the IOS to config the WAN port for SSH, but I still can't connect to it. I have "logging console 7" on so I am able to see that the router is dropping my TCP session requests. I figure this is just the built-in zone-based firewall at work.
Is there a very straightforward process, via the IOS, to allow SSH inbound on the WAN port? I'm not very familiar with the IOS other than basics so while I know how to do things like "transport input ssh" and "login local" and such on the vty 0 4 line, I have no idea whatsoever on what I should do with the firewall stuff. I believce the WAN interface is already a member of the outside zone though so I imagine one just has to somehow include ssh (preferably on a non-standard port) in the exceptions on the firewall somehow.
I have been poking around for a step-by-step IOS guide for this but only find info on configuring SSH itself but not how to open the firewall to allow the connection for it through.

I have a Cisco 881 VPN Router (TX) which connects to the Concentrator at our corporate office (NY). The TX subnet is 10.16.x.x. The corporate subnet is 10.1.x.x, 10.2.x.x, 10.9.x.x.Right now, the 881 router is only used for VPN to corporate, but, I would like to use it our primary router. We have to ISP's, and I would like to allow traffic to come in on either interface to our internal LAN to a few servers.
LAN - 10.16.1.3 / 255.255.0.0 ISP1 - 175.15.110.242 / 255.255.255.240: Gateway: 175.15.110.254ISP2 - 211.106.234.114 255.255.255.240, Gateway: 211.106.234.113Required NAT / port forwarding:211.106.234.115 -> 10.16.9.104 /

I'm trying to forward ports for SQL and VNC using these commands in the CLI:
ip nat inside source static tcp 192.168.1.150 5900 interface GigabitEthernet0 5900
ip nat inside source static tcp 192.168.1.150 5800 interface GigabitEthernet0 5800
ip nat inside source static tcp 192.168.1.150 1433 interface GigabitEthernet0 1433
where 192.168.1.150 is my server (that hosts SQL server and that I want to be able to connect to remotely using VNC) and GigabitEthernet0 is my configured WAN interface.
When I try to connect from an external client I get the error: "Failed to connect to server..." Is this a firewall issue? How do I get round it? The 819 is the only router/firewall in my network.

I purchased an old cisco 831 for practical studies for a cisco certification. I purchased the console cable (serial/rj45) and a usb->serial converter cable. However when I open my terminal application (tera term) After I select the right com port (3) and make sure the connection settings are right. It will just sit idle and not show any data from the device. Was I sold a faulty device? It lights up and has three lights on.
Everytime I look at a manual or cisco video I am given the impression the terminal application will just automatically connect. But whenever I try I get nothing.

configure QoS on 3560 switch i have taken the template from cisco configuration guide since we have different QoS configuration on each model.
below is the configuration :
configure terminal
mls qos
end
mls qos map cos-dscp 0 8 16 26 32 46 48 56
no mls qos srr-queue input cos-map mls qos srr-queue input cos-map queue 1 threshold 2 1 mls qos srr-queue input cos-map queue 1 threshold 3 0
[code]....
Currently all the cisco phones are connected to this switch and configuration with only one vlan that is voice vlan .
1) what is the outcome of this configuration , i mean, what will be the expected output ? end of the day we need to prioritize the voice traffic but why other commands including threshold and buffers are mentioned with respectives queues , if I need to explain that what am i expecting out of this configuration ?
2) this is LAN QoS which i understood but again , do i need to configure policy-map along with class-map which is MQC on this switch ?
3) i have edge router where i have MQC already configured but confusion with this switch which is working as a Access switch .
4) I referred the cisco QoS document for the respetive model whereas we have policy-map configured on the same switch with class-map .
My understanding is if we have configured the LAN QoS , and mapped the CoS value with DSCP , we need not to have MQC.
