I am attempting to configure a Cisco 2901 router using IOS 15 to properly perform NAT/PAT translation between LAN and the internet connection.
My Configuration:
interface GigabitEthernet0/0
ip address dhcp
ip nat outside
ip virtual-reassembly
no ip route-cache
duplex auto
speed auto
no cdp enable
no mop enabled(code)
Why I cant correctly use ip sla command. I only have on my 2901 such commands: ip sla ?
key-chain Use MD5 Authentication for IP SLAs Control Messages
responder Enable IP SLAs Responder
server IPPM server configuration
There is my "sh ver"
ROM: System Bootstrap, Version 15.0(1r)M15, RELEASE SOFTWARE (fc1)
And...What should i do. if i want to create a failover with to WANs
I am trying to implement an etherchannel on a cisco 2901 (IOS 15.1). i have already created the port-channel but i cannot assign the gig interface to the channel group.
View 1 Replies View RelatedI recently installed a cisco 2901 router. The router is connected to hosts using a SG 200-50 50-Port Gigabit Smart Switch
Problem is the router internal interface keeps shutting down without notice and randomly. At that time I cannot ping the interrface from a LAN PC even though I can ping other hosts on the LAN. The ISP link is okay since I can put a static IP on my computer and access the net.
I need to break into a 2901 router to recover the passwords. Cisco's methodology for password recovery on 2900 seriews routerssays to remove the compact flash card and reboot into RMON. There is no external compact flash card on a 2901. Is there acompact flash card inside the box? Or can you use the older method of rebooting and then hitting ctl+break to boot into RMON?
View 5 Replies View Relatedi'm interested if it's possible to set the NTP server via DHCP on an 2901 Router with 15.2(2) image.
i configured the interface gigabit 0/0 as dhcp client. The DHCP Server sends to me DNS, Default GW and NTP. All is working fine, but the NTP will not be configured. i tried to add an DHCP option request, but there is no NTP (42) value. [code]
is there any way to add the value NTP (42) for the DHCP request or isnt it possible?
Does the 2901 have etherchannel capabilities? If so, how to configure it? I mean, I can type "show etherchannel 1" in it, so I would assume if I can show it, I better be able to configure it, right?What about the 2911?

View 2 Replies View RelatedI have a Cisco 2901 with the 4port gigabit ethernet switch module that I'm trying to get configured to have a seperate subnet for each port. So far I have it set up so each subnet is a vlan, then on each port I use the switchport access vlan command to tell it which subnet I want that port to be on. However, there is one port that I need to have 2 subnets on. The way I found to do that was to use switchport trunking on that port, but it doesn't seem to be working properly. how they would configure this? Right now I have vlan 101 as x.x.x.17/28 and vlan 103 as x.x.x.53/30. I think where I'm getting hung up is the proper association between the physical port and the vlan subnets.

I am attempting to configure a Cisco 2901 router using IOS 15 to properly perform NAT/PAT translation between LAN and the internet connection. I've configured DHCP pool for the local interface (GigabitEthernet0/1), which works properly. The WAN interface (GigabitEthernet0/0) is configured to obtain its own IP by DHCP from the ISP. I can work on the LAN computers and I can access the internet directly from the router (using, for example, telnet and router's ping commands). The problem is, NAT does not work properly and connection from the LAN interface does not reach the WAN interface.
View 1 Replies View RelatedI have always done my port monitoring (SPAN) on Cisco layer 3 switches with no issues. This time I am trying to do this on a Cisco 2901 router:
Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.1(4)M2, RELEASE SOFTWARE (fc1)
System image file is "flash0:c2900-universalk9-mz.SPA.151-4.M2.bin
I need to have the source port gig0/0 and destination port gig0/1. There is something about the gig port enumeration (slot/port#) that makes the command rejected. It is self explanatory:
#sh ip int brie
Interface IP-Address OK? Method Status Protocol
Embedded-Service-Engine0/0 unassigned YES NVRAM administratively down down
GigabitEthernet0/0 xxx.xxx.xxx.xxx YES NVRAM up up
GigabitEthernet0/1 unassigned YES NVRAM up up
Serial0/0/0:0 unassigned YES unset up up
[code]....
It doesn't matter what slot or port number I use, it is always rejected. The command is rejected for Both destination and source gig interfaces. I tried a wide variety of slot/port numbers. To my best understanding the complete port names are: GigabitEthernet0/0 and GigabitEthernet0/1, so why does it think there has to be another digit after 0/0 or 0/1? Does it have anything to do with the Embedded-Service-Engine0/0 being administratively down?
i have trouble to get the serial card (2nd genteration T1 card) on up/up state on a 2901 router. the SP guy who installed the rj48 at the demarc says it was tested good. For some reason, it is on up/down state no matter what i tried.

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?
View 4 Replies View RelatedIn 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.
how do i configure the new asa 5505 to be as a router as shown in the diagram note: the isps' routers placed in head office. but i cannot change the configurations of the isp's routers.

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 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.
View 1 Replies View RelatedI'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.

View 3 Replies View RelatedI 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.
